Cobalt Crystalline Herb Stripper Bowl
My cobalt crystalline herb stripper bowl was wheel thrown and hand built from high-fire stoneware. The innovative and beautiful piece can be viewed in action on my Instagram. The crystalline glaze is safe for use with herbs, but is not generally food safe. Please do not use the bowl for preparing or serving sauces or other foods. There is a small area in the bowl which is unglazed (please see in photo). This won’t affect the use of the bowl.
There are many steps to making crystalline glazed ceramics so it is incredibly time consuming, but I hope you’ll agree that the results are worth the effort! I make every crystalline glaze in the studio right before every glaze firing, as the glazes don’t ‘keep’ well. The components need to be measured precisely to the fraction of a gram and applied carefully in numerous, thick coats. Every piece has a single-use, hand built ‘riser’ and ‘glaze catcher’ dish made to fit it perfectly for the glaze firing. This is necessary as the high gloss, two-dimensional crystals need a glaze that flows a lot to develop, and all that flowing glaze has to go somewhere. After the glaze firing, the pieces are removed from the risers and catchers by a number of methods and then the razor edged base needs to be sanded, using 5 different grit sanders until it’s baby-bottom smooth. My crystalline pieces are glaze fired to 1300 degrees celcius over 16.5 hours. They are dishwasher safe, but I recommend to hand wash them to preserve their beauty.
