Cone 6: Sandstone is a matte, vanilla-coloured glaze that contains small and medium-sized brown crystals. The variation of glaze depends on application. As the crystals melt, a variety of blue and purple shades appear.
Cone 10: Colour darkens. Glossy blue/purples become more prominent.
TIP: SW-172 Macadamia is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-172 Macadamia with a third coat of SW-176 Sandstone.
