Interesting.
So Michael Harris must have invented this colourway, but in a sprial formation, for Tortioseshell at IoWSG, independently of his work at Mdina, and much earlier.
Does anybody know when the bullet bowls stopped being made?
I had thought they were all early, at least only up until about the mid-70s, not as late as '78, but I'm happy to be corrected.
I'm asking, because I have an Earthtones Bullet bowl, with an unsual sideways zig-zag pattern, surely taken from the Zig-zags used as surface decoration
I'm not convinced.
