Oops, forgot to drop by and say thanks, Chris & Leni, for your input.

Leni, your red no. 1 vase - is it quite thick compared to the other vase? Mine's quite thick-walled, and you can see the clear casing right up to the rim.
I was just wondering if this was a feature of this pattern, or if mine's just a freak of nature...

I do quite like it, as it doesn't fade to orange on the bulging parts, as with the thinner vases. It's a nice consistant rich ruby.
