I have already entered the recipe into my account at insight-live.com, assigned it a code number and printed a mix ticket for the total I want. I have a scale that tares to zero after adding each material. The slotted dust hood sucks the dust away as I add each. When I pour the dust into the water in the pail, a lot of dust is generated and this hood is even more important. Normally I used a big enough bag that I can seal the top and shake the mix together before adding it to the water.
Leave it mixing long enough under a mixer to thoroughly wet the surfaces of all the particles.This is a powerful mixer that can put a lot of energy into the slurry and it only takes a few minutes for it to be silky smooth.
This table weighs 400 lbs dry and it can remove the water in an hour. If you need to make a plaster table you can find photos here on how to do it.
Using a rubber tool I make cut lines. Even before the center sections are ready I am able to peel them up and turn them over (as has been done on the far right). About half an hour after that it is possible to wedge them.
I combine sections into manageable sized pieces and put them back down to stiffen more. Finally I layer them and repeat a cycle of cutting across the layers and slamming the mass down onto the table each time. Ten cycles of this produces a thousand layers. After a final wedging the clay is ready-to-use, as good as produced in a vacuum de-airing pugmill!
Throw the clay and feel how smooth and plastic it is!
