Slip-cast and press molds, designed in your browser
Any shape in clay. The mold, done for you.
Shape a piece with the design tools, trace it from a photo or sketch, or bring your own 3D model. Claywright checks it will release, places the split, natches and spare, sizes it for shrinkage, and gives you case molds to 3D print and pour plaster into.
Runs in any modern browser. No install, no account needed to try it.
The whole studio, built around the mold.
Making a slip mold by hand takes a weekend of cottle boards and clay walls. Claywright does the geometry, then stays useful from the glaze bucket to the kiln log.
Slip-cast molds
2, 3, 4 or 5 pieces, square or round
Natches, spare and base split placed for you. Four-sided molds release deep lobes and textures. Printable cases with clip flanges, sized and split for your printer's bed, or silicone block-and-case kits for production runs.
Press molds
Handles, humps, slumps and sprigs
Open plaster molds for handles in pairs, plates and bowls, and sprig decorations from any pattern or photo. Any clay body works.
Double walls
Insulated cups, cast in one go
A plaster core inside the mold makes two walls with air between, fused at the rim, with the vent hole in the foot.
Photo to profile
Turn a thrown piece into a mold
Photograph one of your pieces side on, or snap a sketch. Claywright traces the edge into a profile you can tweak, then make a mold from.
Casting
Drain time that knows your plaster
How long to leave the slip in for the wall you want, allowing for plaster thickness and how many casts the mold has done today.
Glazes
Chemistry, limits and Australian materials
Unity formula and cone limits for every recipe. Swap US materials for what Walker, Keane and Clayworks stock. Line and triaxial blends, a test tile library and bucket labels with QR codes.
Firing
Schedules, cones and cost
Edit a schedule, see the cone it reaches and what it costs, export it for a Raspberry Pi kiln controller, and keep a kiln log.
Making
Ribs, slab patterns and rollers
A throwing rib cut to your profile, slab templates on A4, the clay to wedge, a shrinkage ruler, stamps and texture rollers.
Studio
Pricing, inventory and logs
True cost and wholesale price per piece, materials that count down when you mix, a mold log, and projects you can reopen.

Questions
Anything else: write to the address in the footer.
Do I need a 3D printer?
For the printable case molds, yes: any filament printer that prints PLA. Parts bigger than your bed are split automatically. Without one, you can still design, use every glaze, firing and studio tool, and soon order printed case kits posted to you. Register your interest.
What is a case mold?
A mold of the mold. You pour plaster into the printed case to make each plaster piece, then keep the case to make the next set when the plaster wears out.
Does it allow for shrinkage?
Yes. Pick your clay body or enter its shrinkage, and everything you export is scaled up so the fired piece comes out the size you designed.
What if my shape won't release?
The release check colours anything that would hook the plaster in red before you generate. Turn the split, add a base piece or go to four sides until it's green.
Can I import my own model?
Yes, STL or OBJ. Claywright repairs the mesh, adds a pour sprue and air vents where they're needed, and you can place them by hand.
Where is my work saved?
In your browser during the beta. Accounts that sync projects across devices arrive with Pro.
Are the glaze figures safe to rely on?
They're calculations to compare and adjust recipes, not safety tests. Food-surface glazes still need a leach test, and a test tile decides what a glaze really does.
Can I get a refund?
Yes, within 14 days, no questions asked.
