Welcome to Part 2 of the Clay Sculpting Master Series. Just a quick reminder that Part 1 focused on planning and composition, this page focuses on professional execution and structural engineering needed for master clay sculpture techniques; the constraints and methodologies required when sculpting a 'master' piece destined for industrial factory production. Part 3 looks at clay sculpture detailing and finessing, from to lace to trims, folds and foliage. It looks at how surfaces are refined, patterns and textures created, hair, faces, fabric, and flowers brought to life, and how those decisions reveal themselves in the finished collectible. The fourth guide is a run down on which tools to use for clay sculpting - basic to advanced.
The central challenge in sculpting for bone china factories is the absolute ban on internal supports. This single constraint elevates the process from art to an architectural problem that must be solved compositionally and structurally before the first mould can be taken.
Inside, we will break down the essential strategies for working without armatures for master clay sculpture techniques and follow a detailed case study of a real Compton & Woodhouse commission, tracing the 160-hour journey from initial brief to final approval.
When collectors admire a Royal Worcester figurine with outstretched arms, delicate fingers holding flowers, or elaborate flowing drapery, they are seeing the invisible result of structural engineering decisions made during the building phase. What appears effortless required careful planning and master clay sculpture techniques to achieve poses that survive both creation and factory production.
This section reveals why prestige bone china figurines are extraordinarily difficult to produce, and why understanding 'armature strategy' helps collectors evaluate quality.
The critical difference: Water-based ceramic clay destined for factory casting cannot contain permanent internal armatures. Metal (or any non-clay material) inside the piece would not be able to be cut int segments by the mould makers and would also expand and contract differently than the clay - as well as restricting the pose iterations when composing the piece.
We do not use skeletal internal armatures when sculpting a production figurine piece for bone china factory production
Unlike oil-based clays or polymer materials where wire skeletons are embedded, and a silicone mould is taken for reproduction, bone china masters must be completely "cuttable". This is because factory mould-makers slice through the piece from any direction to create production moulds. Hidden wire or rigid supports render the sculpture impossible to make slip casts from.
This constraint is why mastering bone china figurine sculpture is a rarefied skill. You must engineer stable, graceful poses without the internal skeletal support other sculptors rely on. It's architectural problem-solving disguised as art.
Although permanent armatures are forbidden by the factories, professional sculptors still build complex pieces by the use of external armatures and sometimes building parts of the sculpt separately. Solutions that translate to master clay sculpture techniques are part artistic, part logistics, part engineering solutions.
Commonly built separately, then joined:
In this example, the items that were made separately were the musical instruments, the extended arms and the stool. Note the external armature supporting the arm with the tambourine
Without permanent armatures, professionals use supports that mainly disappear before factory handover, but not always:
Just as construction uses temporary columns to hold up a structure before the permanent supports are set, a clay sculptor for bone china factory slip casting production uses a temporary post to support the heavy head. Once the featured fashion collar is applied and firm, it becomes the permanent support
Sometimes, to manage the weight of heavy sections during sculpting without an internal armature, a clever master clay sculpture techniques is to place a temporary support post. This brace is made of the same clay as the rest of the piece so it can be joined securely. I want a neat looking post, which I make with a clay extruder, because my eye can then ignore it. I can then go ahead and detail the upper sections without the head falling off and ruining the face and other details.
Once the featured collar is completed, it provides a permanent structural support, allowing the temporary post to be removed.
The best solution to structural problems is often compositional, designing poses that are inherently stable:
The edge of the cape is razor thin, giving the optical illusion of a light cape flying with movement, but the cape becomes much thicker where it is hidden, acting as an external armature to support the piece
The thinness of the flying cloak is a clever optical illusion.
Factory technicians must be able to:
To support the double figure, we went beyond the four legs, adding a structural snow mound at the rear. Simultaneously, we addressed the gap under the front skirts, carefully sculpting the form to eliminate undercuts and allow the entire piece to be moulded in a single section
Our approach on ‘I Love Emily’ (Royal Worcester) solved both structural and practical needs. The supportive snow mound at the rear stabilises the figure, while the sculpting of the front skirts elegantly fills the gap to the ground, without undercuts, a design choice that also permitted this section of the piece to be moulded in one single, efficient section.
“Can I Come Too?” for Royal Worcester, posed a classic sculpting challenge
Creating 'Can I Come Too?' for Royal Worcester, for bone china production was technically demanding. The boy's form, lacking the structural support of a more usual female figurine with a long dress, relied on only the satchel and puppy. Despite strong external armatures in place, it broke into pieces during transit back to the Worcester factory, the only time this ever occurred. Thankfully, the technician was a talented artist himself and expertly put it back together without needing my involvement. So for once, with this tricky piece, my master clay sculpture techniques let me down.
We made the "impossible" possible. This Royal Worcester figurine was the first to feature a separate lock of hair, made viable by a pioneering internal armature
Sometimes you have to invent new master clay sculpture techniques. We made the "impossible" possible with Tara (Royal Worcester). We devised a two-stage internal armature solution. The long, free-flowing lock of hair required a method to prevent slumping during the wet stage and subsequent warping during drying. This was achieved by a pioneering technique (in the modern age) using an internal armature to hold the shape during sculpting process which was not removed. It was cast for moulding with the armature still inside. Worcester added a thin internal support during production for each piece. This groundbreaking technique resulted in a sold-out edition of 7,500 proving the innovation was a success. We achieved what was once thought impractical and broke the rules to make history. We pioneered the use of an internal armature to create the first bone china figurine with a separate, free-flowing lock of hair held in the hand - a feat once deemed impossible by the Staffordshire and Worcester bone china factories.
Understanding building strategy reveals quality markers collectors can evaluate:
Of course, there is is no hollowing requirement for bone china slip casting production, but those making one off pieces to subsequently fire will need to be hollowed before firing. Solid clay sections thicker than about half an inch will likely explode during firing as trapped moisture converts to steam. Professional figurine work for factory production does not need to requires no hollowing.
Amateur clay sculptures need strategic hollowing if they are to be fired. You can see the amazingly talented Philippe Faraut showing you blow by blow how to remove complex and embedded internal armatures and hollow a finely finished sculpture here: (note the relaxing music soundtrack to make the process seem less difficult).
The technique is to cut into sections, hollow out the clay, then rejoin. You cannot allow to clay to be too wet or too dry. You need to find the 'Goldilocks zone'.
What collectors see: graceful, effortless poses that appear to defy gravity.
What actually happened: careful choreography of separately-built parts, temporary supports extracted at precise moisture stages, strategic hollowing, and compositional engineering, all executed within the constraint of zero permanent internal armature.
Where Art Meets Engineering. Each seemingly weightless pose is a carefully engineered structure, built piece by piece to achieve its graceful balance
This hidden discipline of building in parts and using only armature usage, separates prestige factory work from hobby sculpture and is one of the key master clay sculpture techniques. It's why bone china figurines from Royal Worcester, Coalport, and Royal Doulton command premiums; the technical mastery required is genuine, rare, and impossible to fake.
For sculptors: Building in parts and the use of external armatures is not a shortcut; it's professional methodology enabling poses and details impossible through single-mass construction. Master this, and you master the medium.
For collectors: That an apparently simple, complete, flowing, prestige figurine represents engineering solutions most sculptors never learn. The more you understand the constraints, the more you appreciate the achievement.
The culmination of all the previous stages of master clay sculpture techniques - preparation, proportional planning, compositional verification, and structural engineering, occurs when the master sculptor begins work on a definitive factory commission. This section details the professional workflow by tracing the creation of a piece designed for Compton & Woodhouse from start to finish.
A commission for a double angel figurine for the Compton & Woodhouse Music Box collection. Left: Original Illustration. Right: The Finished Commission
Compton & Woodhouse were exploring manufacturing certain bone china ranges in the Far East for economy. One range was their Music Box editions. They sourced a factory and had illustrators there create a concept drawing for a 'Two Angels On a Cloud' design.
The factory claimed they could handle the sculpting as well. Compton commissioned it, but the result fell far below their standards – the Far East clay modellers understood cutesy caricature and could work really fast, but not the refined elegance Compton were after. Compton rejected the sculpture and came to me to create the master sculpture properly. So the Far East factory had all the master clay sculpture techniques (probably more than me), but not the required artistic vision.
This is where real factory production standards become visible: not every sculptor understands the technical requirements, systematic approach, and refinement level that prestige bone china demands.
Compton & Woodhouse commissioned a double angel figurine for their Music Box collection; two celestial figures in flowing robes, wings extended, capturing a moment of divine connection and love. The brief specified approximate 8-inch final height (post-firing), elegant rather than dramatic, suitable for their collector demographic seeking spiritual themes with classical refinement.
Timeline: Four weeks to deliver production-ready master
This project demonstrates every principle from previous sections: preparation, proportion, composition, building in parts; all converging in one real commission under actual deadline pressure. This is a great case study to show all the required master clay sculpture techniques.
---Before touching clay, I gathered references: Renaissance angel paintings, wing anatomy studies, fabric drape examples, fabric reference photographs of my daughter in long flowing robes from every angle. Using the shrinkage calculation from Section 3, I determined the master must be sculpted at approximately 10 inches to fire down to the specified 8 inches after drying and firing shrinkage.
Rough compositional sketches explored how two figures could share space without crowding. The solution: subtle lean toward each other, wings angled to create negative space (though wings would be separately manufactured slabware), one figure slightly forward to establish depth.
Day 1-3 - References gathered before clay sculpting work begins
I began by plonking down a mass of raw clay to get a sense of the height and scale I was working with.
You have to start somewhere
A lump of clay is intimidating; cold, wet, clumsy, slow, annoying, inert, slippery ugly mud that isn't helping at all. In the first instance, it's the enemy. I have to visualise the clay going from adversary to ally. This is where the "hook" comes in.
Following one of the most important of the master clay sculpture techniques - (never detail what isn't composed correctly), I began with a lump of cold clay, roughing out in my mind where both figures would be interconnected and integrated, essentially planning both the position and scale of the angels and their base.
With my anchored lump of clay on the bat, I measured and marked off heights: where the top of the head, shoulders, hips, knees would be. On this angel figurine, I knew the top of the lump was precisely where the waists of the angels would be.
How did I know? I measured (a recurring theme in my own master clay sculpture techniques).
Scale guide drawn to match the sculpture's proportions. I measure constantly, referring with dividers to my drawn scale guide (like a pin-man on paper)
At this stage, the piece looks crude, barely recognisable. That's correct. I'm establishing:
One of the most important master clay sculpture techniques for me, not often talk about, is the 'The Hook'. The "hook" is my name for the starting point within the sculpture, the place that stops it being just a daunting lump and becomes something my imagination can work with. It's a kind of psychological trick to get me over that 'hump'.
I know where the waists of the angels are going to go; in line with the top of the central heart
For the two angels, the visualisation or "hook" was the central heart shape around which I would build the design. Once this heart shape was roughed out, I started feeling the shape of the dresses around each side. At this point it's all about feeling your way; making little positive visualisations.
I could now begin to see how the lovely flowing robes could be developed from the shapes in the clay either side of the heart
It may not look like much in the photo, but for me I could suddenly see how the lovely flowing robes would develop from the shapes either side of the heart. Each sculpture has a visual hook which gets the piece going. See how I build this sculpt around the central heart. The piece was no longer just stubborn ugly clay, it had started to morph into a sculpture.
The hook is the thing that begins the conversion from enemy to ally.
Using the hook and imagination, I can now "see" the design and continue the conversion. I know where things go because I've measured and marked.
Now it's time to add the parts that should be there: let's start with two female upper-body torsos.
This phase embodies the "compositional refinement" stage:
I worked the torsos off-sculpt (see Section 7) and added them either side of the heart
Being systematic and precise at this early stage simply paves the way for later artistic interpretation. It saves all the time-wasting of changing a model because the proportions are wrong. True creativity is always the bedfellow of precision.
In that same vein, I now placed the heads I'd been working on as separate parts.
I have worked on the heads and faces separately and now I am adding them to the heart
These torsos and heads were by no means finished, but they were a good starting point to work on the overall composition. Both angels roughed out, forms beginning to appear. No wings, those would be made as slabware and cast completely separately, then joined in production. But proportions, faces, and gestures begin to get established.
Time to make the hair for the two angels. I decided one would have straight hair, the other wavy. The straight hair is more straightforward; the wavy hair required a special technique I discovered through trial and error - something I call "wet clay sculpting."
There's one technique (not that well known) which involves working much softer and more pliable clay onto your piece for certain jobs: ladies with lots of flowing hair, frills, dress folds.
I find this technique is where ceramic clay comes into its own, although it can also be done by heating up oil-based clays like plasteline.
Simply push and pull the pliable clay into desired position
Note the square hollow in the hair - a fixing for production to add wings. The four wings I'll make completely separately; they will never be applied to the angels during the sculpting stage and will be sculpted separately.
As the wet clay I applied for the hair gradually dries, it shrinks back to create interesting shape details. When the clay has merged back to the same consistency and these previously wet, soft additions are now workable with a tool, I can now work this into lovely delicate flowing details.
There may be some splits and cracking to attend to, but I simply press a tool into the crack to consolidate, then fill.
---Now the essential elements are in place and definitely the right scale. It's at last time to get into composition proper.
Having done the hard grunt work, we're now allowed to get a bit arty. If you're anything like me, this is the bit you've been waiting for. It reminds me of doing interior design once the structure of the house is built. The difference is... you build the house too!
This is party time. Time for exuberance and self-expression. For example, I love doing hair. I use lots of very wet clay and fold it in with tools and brushes, then let it dry for a day or two while I work on something else.
In this instance, I had to figure out what was happening at the back. I wasn't sure what I was going to do here (clouds or fabric). I didn't have any references, a major problem for the part of my brain that feels naked without references. I felt a sweeping train maybe needed to go onto the back of this figurine (better than couds).
With no reference guide from C&W for the back of the sculpt, I had to do my own thing (clouds or fabric - maybe floaty cloud-like fabric
So I just improvised by rolling out a slab of clay and mucked around with it for not very long, and was reasonably pleased with what came out, so had the wisdom to stop.
Sometimes you need to know when not to over-work something. The folds on an angel's cloak out of sight on the back of a sculpture could have many different solutions, so don't sweat it too much.
The shape of a female arm (quite a complex yet specific series of planes) needs to be worked on until it's totally right, no matter how long that takes; BUT not yet. When the time comes in the detailing segment later. Meantime, the angels can have approximate arms, and the skill of positive visualisation can do the rest for now.
So this part can be fun. Who needs food or sleep? Humans can work for really long periods when in this frame of mind. This is when the donkey work is done, and it can be done quite quickly at this stage because the foundations have been laid correctly.
Composition flowing; all major elements in place but still rough
Before any cleaning, smoothing or fine detail begins, the piece must pass the critical checkpoints of master clay sculpture techniques:
I had a meeting with the commissioning art director and once agreed we photographed the piece from all angles and sent images to Compton & Woodhouse's head of design for approval before proceeding. Note: there is lots of money and shareholder interest in the success of projects like this which may reach reasonably high volumes (in the millions of pounds).
This moment is crucial. Once detail begins, major compositional changes become extremely difficult. Getting approval here prevents wasted effort later.
One of the most important takeaways from this type of commission: I DID NOT START DETAILING UNTIL I KNEW I WAS NOT GOING TO CHANGE ANYTHING.
Before I put any detailing on any model, I always get the client's product development team to OK everything about the composition. If they then want to fine-tune anything about the composition after I've done detailing and it has to be redone, they get charged an extra fee. We are doing art, but we are also in business – and this is a transaction.
So as discussed, detailing only begins in earnest once the overall composition is finalised.
The very last thing I want to happen is to carefully place lots of intricate time-consuming details only to have to scrape them all away because there's something to change within the composition.
I ask friends, colleagues, and, obviously, the product development team, I trust to give a fresh eye. Don't punch them if they say something is wrong; embrace them and their comments. Something inside was likely already telling you the same, but you weren't quite listening.
By "composition," I mean how the piece flows. Are there any awkward angles? Are the arms in the right position?
Following principles from Section 9 (fine detailing), the detailing work comes after every compositional and structural decision is locked in. I need to balance:
Each face will take approximately 6-8 hours from rough volumes to refined features.
Expressions refined - serene but individualFabric folds received hierarchy of detail for master clay sculpture techniques:
There is a great time lapse video of sculptor, Jon Burns showing how he applies folds. This is worth a watch to get an insight of the practical side of laying on and shaping clay.
Fabric folds refined with hierarchical detail from large to smallThe last days involved systematic verification:
Minor adjustments made: a fabric edge softened here, a feature redefined there. Professional work is 95% right, then refined to 100% through patient final review.
I can look at the finished angel sculpt now and be critical. Unfortunately, it's too late; I got my fee and moved on.
This piece sold well for Compton & Woodhouse and unlike the Far East factory attempt at this commission, was exactly what the product development team wantedAn important principle of master clay sculpture techniques for factory production is that the wings were made as completely separate pieces from slabware (rolled-out slabs of clay). They were kept separate from the main sculpture, as they would have needed internal armature to stay attached during the sculpting process and transit—impossible for bone china production requirements.
The square hollows visible in the hair are production fixings where wings would be attached during manufacturing assembly, not during the sculpture stage.
The finished master was carefully packed and delivered to Compton & Woodhouse's production facility. From this point, factory mould-makers would:
The master itself is cut up and destroyed during mould block/case-making but the permanent reference is obtained by creating an exact replica of the original master sculpture from the first pour of the master mould for quality control throughout the production run.
Total: ~160 hours over 4 weeks
This matches the professional workflow percentages of my master clay sculpture techniques:
What this timeline doesn't show: The years of practice enabling each stage. A beginner attempting this same piece might need 400-600 hours and still struggle with the structural challenges and technical requirements.
Once in production, this design proved:
This commission wasn't special because it was perfect, it was typical professional work: systematic preparation, disciplined composition, intelligent problem-solving (the separate wings solution), deadline management, and factory collaboration.
When examining the finished bone china double angel in a collector's cabinet, nothing visible suggests:
What collectors do see, and respond to instinctively, is:
This is why understanding the master sculpture creation process matters for collectors: It reveals the invisible foundation of visible value.
Page 2 has focused on the dual challenges of structural engineering (creating dynamic poses without internal armatures) and the professional workflow required to create a production-ready master sculpture for the factory. We covered the necessity of part-building, temporary supports, and the critical approval process to prevent costly changes.
The master sculpt is now complete and delivered. Attention turns to the final refinement that separates adequate work from collectible excellence, the high-level techniques used to create photo-realistic facial expressions, intricate fabric texture, and delicate accessory details.
What does the experience of a 160-hour factory commission ultimately teach us? It strips away all romantic notions of sculpting, leaving behind an uncompromising demand for structural integrity and sheer, disciplined endurance. The lessons synthesized in this guide, from the initial welding of external armature supports to the final factory production of the case study, reveals that the true job of a pro modeler is often built on steps no collector will ever see.
The Timeline Reality shows that 160 hours is not an estimate; it is the minimum entry fee for professional-grade execution. It proves that the difference between an art studio model and a factory master may just be the capacity to maintain meticulous focus over months, constantly fighting the clock while upholding material standards.
For the collector, this process delivers a singular insight: the value of a piece is directly correlated with the sculptor’s commitment to these non-negotiable structural and time-intensive phases. You are not buying clay; or even gorgeous glistening, romantic bone china, you are buying the hundreds of hours of discipline it took to bring this flawless structure to life thanks to, not only the modeler, but the artisan team at the factory too - bringing with them the knowledge passed down over centuries .
