This was great. I Just (minutes ago!) order a syphon and strainer so I could try to make my first Sig batch! I like your quick and easy way!! Thank you for sharing. Oh! what if you want to make it a color Sig. When would you add a colorant? and you don't have to worry about a hydrometer?
As a deflocculant, Darvan 7 weakens the electrical attraction between clay particles and thus acts as a thinning agent in slips and as a general dispersing agent for clay bodies and glazes. It is mainly used to enhance the fluidity of casting slips and maintain or slow the shrinkage rate. It binds to the larger pieces of the ball clay and sinks them so that you are left with the ultra fine particles on top.
