I can mix all this powder into that little bit of water to make a casting slip. How?

Friday 21st November 2014

This is 8.4L of water (in the bottom of that pail) and a 20kg bag of Polar Ice porcelain casting clay. Amazingly, 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 2/3 of this 5-gallon pail. How is this possible? That water has 100 grams of insight-live.com/material/260">Darvan 7 deflocculant in it, it causes the clay particles to repel each other such that I can make a liquid with only a little more water than is in a throwing clay! All it takes is a few minutes under a good power propeller mixer.
