Duncan Crackles Glaze

Remember when “cracking” was a bad thing? Sidewalks, windows, cups … That’s a thing of the past, thanks to Duncan Crackles Glazes! These specially formulated glazes create cracks similar to crazing when fired, resulting in a distinctive aged, antique look.
For extra depth, highlight the cracks created in the firing by antiquing the piece with ink or acrylic paint.
