Periwinkle Crystalline XL Mug

My periwinkle crystalline xl mug was wheel thrown from high fire stoneware. I have discovered that this stoneware is sensitive to thermal shock and is not suitable for boiling water. It can be used for hot but not boiling liquid, so I’ve reduced the price.

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! 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, 2 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.
