A range of quality powdered earthenware glazes. Glazes marked (LS) contain a low-solubility lead frit. For ware in contact with food or drink we would recommend using glazes marked (L) which denotes 'Leadless'. For glaze preparation advice please see the main powdered glaze category header here.
Powdered glazes, once mixed with water according to the recommended guidance, are suitable for dipping, pouring or spraying onto the piece. They are not suitable for brushing-on without addition of a glaze binder such as Pehatine. If brush-application is intended, we would recommend you select one of our ready-mixed brush-on glazes instead.
Transparent glazes must be applied thinly and fired/cooled on a fast schedule to avoid ‘milkiness’ and/or crazing in the fired result.
Artistic/special effect glazes usually require a generous application to achieve the desired effect. Please note the individual product descriptions for product-specific guidance. Some special effect glazes can melt/flow considerably during firing so please take all necessary precautions, especially with regard to protecting your kiln furniture (stilting, batt wash etc.).
