Duncan Crackle Glazes

These special effects glazes are among the easiest to use and they create some of the most dazzling effects. Crackle glazes create random hairline cracks with interesting patterns.   They allow some clay colour to show through the glaze.  They are non-toxic but not recommended for dinnerware (as the fine cracks can harbour food particles and bacteria)

During the firing process, the gloss glazes develop fine, spider-web cracks in the glaze surface.

Emphasize the crackles with an acrylic colour or stain. Duncan Crackle Glazes are available in Clear Crackle and 3 additional colors.  All glazes are translucent and may be used over underglaze e.g Duncan Concepts or EZ Strokes.
