Rather than L4807 being just another cone 6 whiteware casting slip recipe it is a pattern of the flexibility potters could have in making their own bodies. This deflocculates easily and casts with incredible speed.
Typical slips made from ball clay and talc (or mixes of common feldspars, clays and quartz) take 20 minutes to get the needed thickness (in our circumstances and assuming a new dry mold). But this one pours out in 12 minutes. We are used to extracting pieces in 30-60 minutes, with this clay I can demold in 10 minutes. In this case the secret is the recipe: It employs OptiKast Kaolin and KT#1-4 ball clay, both are large particled clay's targeted at slip casting.

How would you like to be able to create a parametric CAD model of a teapot lid? Then 3D print a case mold and pour a multi-piece plaster working mold? Imagine easily making multiple-size one-off molds to accommodate any teapot you throw!
This is perfect for M370 or Polar Ice (both have throwing and casting versions). Or, how would you like to be able to formulate a casting slip having the same appearance and degree of maturity as the throwing body you use? More information coming soon (based on the L4807 casting body).
Next, imagine casting the handles, rims and spouts also. Information on how to draw and print them also coming soon.
