It does appear to be a bit of a mystery, Ronnie. I can see why you went for it - it does appear to fit in with Ysart styles, they made this shape of bowl too, as I'm sure you know.
(For others, Salvador Ysart trained/worked at Schneider before coming to Scotland with his sons.)
It doesn't look like any of the Nazeing-style of stuff, (which often has an almost crizzle effect in it) that is often described as "Scottish Glass" which is a different mystery all on its own. This does not belong with that.
This is something good. I just don't know what.
