Can you mix all this powder into that little water?


Tuesday 15th July 2014

This is 568cc of water and 1400 grams of Polar Ice porcelain casting clay. Amazingly enough it is possible to get all that powder into that little bit of water and still have a very fluid slurry for casting. The volume will increase to only 1065cc. How is this possible? That water has 13 grams of Darvan 7 deflocculant in it, it causes the clay particles to repel each other such that you can make a liquid with only little more water than is in a throwing clay! All it takes is 15 minutes under a good power propeller mixer (in a bigger container of course).
