I love texture and while I typically hand build textured mugs, I also love the symmetry of thrown work. So I experimented with throwing a handle-less mug & when it was soft leather hard and just after trimming, I put a cardboard cylinder inside and carefully rolled it over a textured mat.
The outside is glazed in a turquoise matte glaze, while the inside and the outside rim is glazed in a turquoise gloss. Where the 2 glazes overlap, is a green boundary line.
The clay is a speckled stoneware and sadly, the overlap of the 2 glazes caused crazing on the outside. The pieces I did with the same technique and glazes using B-mix (a white, unspeckled stoneware) fit better.
