This is the original Cone 5 stoneware casting slip. Fires well in both gas and electric kilns. For a semi-vitreous, hard ware, Moroccan Sand makes a reliable stoneware slip that can be case in all standard molds.
Used for slip casting into plaster molds. 1 gallon and 5 gallon containers have premixed slip, ready for you to use (although minor adjustments may be necessary). 50# bags of dry slip requires mixing with water and deflocculants such as soda ash, sodium silicate or dispersal/Darvan to get proper results. Mixing formulas vary. See Laguna's web site for mixing information.
As a general guideline, 50 lbs of dry slip mixes with about 3 gallons of water to make about 5 gallons of slip. However, slip needs to be mixed to achieve the desired viscosity and the specific gravity. Here is some slip-making instructions from Laguna.
