AMACO ST Stone Rust is a smooth, active stone-textured glaze that breaks and flows to accentuate texture much like Vintage "mottled" pottery.
These glazes have a smooth, unique stone-like surface when fired over a mature Cone 04 bisque. The ST glaze series flows a little in the firing, settling in the crevices and towards the bottom of a vertical surface. Therefore, when applied over a textured surface they will produce antique-like variations or a weathered and worn out look on the higher relief areas of the piece.
Because they move slightly, care should be taken to taper down the glaze application towards the bottom of the piece so that the piece will not stick to the kiln shelf during firing.
