Description
Fine grained low plasticity cone 10 melting silty clay. Ravenscrag Slip is a blend, its principal ingredient is mined from a large deposit near Ravenscrag, Saskatchewan, Canada. It was originally developed as an almost-complete base cone 10 glaze (it is feasible to use 'as is' on either green or bisque fired ware, to achieve a light colored silky matte surface). The material can be viewed as a 'plastic feldspar' that provides good melting and excellent slurry properties in a light colored material. In educational and beginning pottery settings it is an ideal starting-point for material-blending style glaze development and experimentation with colors, opacifiers, variegators and matting agents.
