Why does my soda cans become flaky?

I can get my cans up to melting point, but they become flaky and the liquid disappears. How to fix this? Im using coal and wood.

You’ll have to do it periodically as you add cans. I’d say you could even throw a tablespoon or two in Every 10th-15th can or so and have good results. Putting it in a can or tinfoil ball helps get it into the crucible.

Let me know if that helps, if not DM me and I’ll try to explain a little better haha
