High-fire glazes, such as this, should be used on high-fire clay (meant to be fired to cone 8-10).
To apply: Always mix first before each use! Then brush or dip onto bisque-fired pottery (pottery that has been fired to cone 08 - 06).
If brushing, apply three layers, alternating the direction of the brush strokes with each layer to create a smooth finish. Let dry completely between each coat (until it completely loses its sheen), but do not over-dry or the glaze may crawl.
If dipping, dip and hold in the glaze, then remove from the glaze and shake off the excess. The amount of time you hold the piece in the glaze will dictate the thickness of the coat. We recommend 1 dip. A second layer can be applied, but more layers can result in the glaze running off the pot. Let dry until it loses its sheen between each coat if you are adding additional coats. Fire to cone 8-10.
If the consistency seems thick, first mix thoroughly. If it still seems thick, add water SPARINGLY to thin it down. If too thin, leave the container open to let some of the moisture evaporate.
Note that mixing glazes together or applying one on top of the other may cause the glazes to react differently than you expect. We recommend that you always test a new glaze combination and clay/glaze combination to see how it performs.

Questions & Answers

Hello! For this specific dry mix, how much water exactly should be added per lb? Thank you.
We don't have specific ratios of water to mix for each individual dry mix, but as a general outline, we recommend 5-8 oz depending on if you're brushing or dipping. Start with the minimum amount of water, mixing well to ensure there are no clumps. If the mix is too thin, please let is sit over night to allow all the raw materials to absorb the water. If the glaze is too thick, you can let the mixture sit overnight and slowly add the remaining water the next dy.
