I had heard that it wasn't meant for wood. The problem is getting embers right up against the aluminum wall that cause the sides to melt. This seems especially true when your doing something more substantial than boiling water.

I am going to make a penny stove to setup inside it as a when burning wood is not allowed.

If this works well enough, I will probably bite the bullet on something better that burns wood. Without getting into the aluminum debate, I feel that the only thing aluminum has going for it is that it is light. I do know it does not like to interact with stainless
