I have only used the tin once for the time being, to bake bread on leaven.
The advantages:
- no need to use baking paper, the bread does not stick and is easy to take out
- the mould will probably last, unlike steel, which is finally starting to rust
- easy to clean - in the dishwasher
Minus:
-so far, one small one - the form holds the shape poorly, so the bread grows wide in the middle. However, I do not think this has much effect on its quality.
