| The copper matt glaze produces a range of colors, including lusters and opalescence, and is very receptive to post-fire reduction. Apply a thin coat of glaze then wipe off with a dry towel to achieve a matt, speckled surface. Use in combination with the white crackle glaze for a mottled effect. |
