dense slip for spikes quantity darvan 811 or sodium Silicate
Posted 04 December 2012 - 09:19 PM
I want to be able to make spikes as large as possible by squeezing them with slip (I suppose dense could be nice).
I would like to do the slip from the clay (cone 04) I am using, I have darvan 811 and sodium Silicate (to reduce water content-shrinkage/crackings) but I don't know what quantity should I use, the formulas I find are for too big batches.
Is there some possibility to do about 2 pounds of slip?

I would take a very thick, sludgy, non-fluid slip, like almost thick enough to form into a shape, and deflocculate it by eye. Mix equal parts water and deflocculant and and add it a couple drops at a time to your sludge until you get the viscosity you need.
