How long do I have to heat metal
The time it takes for a metal to become pliable varies with the type of metal and its thickness. Some metals can be heated in as little as 30 minutes, while others require several hours or even days to complete the process
To make sure your metal is ready for use, look for small bubbles that form when you heat it. These are indicators that the metal has reached its working temperature. You should also check the color of your metal by holding a piece up to a light source; if it's white or gray, it's ready for use; if it's blue or black, it's not yet done heating up enough to be flexible.
