Hello - sorry about being a complete beginner.

I have a heart shape made from art clay, fired by using a torch, which was not a very good replica - so I thought perhaps I could "repair" it by using art clay paste on it, and then "re-firing" it, also with a torch.

This has not turned out very well! So how would anyone else do it? Should I have used soldering items, such as safety pickle, and pallions?

I would very much appreciate any help here.

Thank you.
