I've just received this little dish - sold as a paperweight - which is signed on the base 'J MacDonald 2003' (or that's what it looks like to me!)
It's an interesting effect, with swirls of orange and purple in clear glass, pressed into a ribbed mould.
Can anyone tell me anything about 'J MacDonald'? I've 'Googled', but didn't find anyone I thought likely to be her / him.
