Squared Vase With Single Roses and buying a Shino Glaze

This squared vase was hand built and shaped with a Surform tool. It's made from white porcelain clay and fired high to cone 10 and soda glazed. There is a clear glaze on the inside. I've cut out sections of the bottom for giving it a lighter look. I've painted with colored slips single roses on each side. I think it will make a great vase for a bouquet flowers.
