The answer: With precision! This squat cylinder was quite an accomplishment. First of all, it takes an exacting skill to shape a pot like this – with such acute angles. But, what really gets me going is the fact that the stripes have been applied using such mathematical exactitude – it has been done off the wheel; it has been done by using tape (this is commonly known as a tape resist), in which a glaze has been applied, followed by taping up the area NOT to be glazed a second time; the tape work has to be placed at an equal distance to the next tape resist area (you will see that THAT has been accomplished exactly!) Then the second glaze is applied. … I do not know what happens next. I presume the tape is removed to reveal the two glazes – then the pot is fired. However they managed it I stand amazed at the finished result. Wonderful! The only question remaining (and the question that has burned so deeply within me … for a long time) … is – WHO made this? The mark underneath might help a bit - but as you can see the glaze has run into the mark. I bought it in France so it could be a French potter, but I have a sneaking feeling that it is not - anyone have any ideas? I posted it on the other pottery forums but came up with a blank!
