These unusual and interesting glazes give best results when applied thickly and fired on flat surfaces. Results will vary on vertical surfaces and thinner application. Glazes marked LS contain a low-solubility lead frit. For ware in contact with food or drink we would recommend using glazes marked L (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.
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.).
