Terra Cotta Casting Slip is a popular red casting body which produces quality, smooth ware.
It is non-vitreous, meaning it will absorb over 7% of its weight in water when submerged, and is therefore only for indoor use.
It can be used in all kinds of molds.
As a general guideline, 50 lbs of dry slip mixes with about 3 gallons of water to make about 5 gallons of slip.
To get the viscosity and specific gravity that you want, you will have to make the solution in the best ratio that works for you.
This slip fires up to cone 06-04.
