Molding en noyau. Mixing of sand
Once you have reheated your sand, that is the plaster, the stone alum and the brick, and once you have finely filtered them through a cloth sieve, # mix them the following way: take four measures of plaster, two measures of bricks, and one measure of stone alum. Mix them all together with the hands, so that one may not discern one [ingredient] from the other. Once your sand is ready, you need to kill the animal that you wish to mold in this way.

except for the stone alum which should be ground in a mortar.
