Thanks for your replies, all, sorry for the delay. Stella, I never lidded this creature, should have though as I'm sure it'l bite:shocked2:Yes, it is from a candle fo supplier where I buy most of my fo from. It is called Antique lace. When it was first poured, I knew something was wrong as the one side looked a bit honeycombed. The one pic is after first burn and the other after the second. It looks like there are living creatures in it and the brown just appeared, there is no colour added and the tin is not rusty, it is alluminium and new. Me thinks it is most definately the fo. I sent the pics to the fo supplier and asked for an explanation, but to date all is quiet.............:tiptoe:
