This happended a while ago and I have since learned that the molten zinc is not hot enough to burn out the hot glue but I just ran into these old photos that I liked. I think the hot glue make these great shapes that are fairly organic. This hot glue tree was coated in plaster before the attempt. I think that maybe if I did a pre burn out in a oven this might eventually work as the glue melts at 400 degres but just does not vaporize like the foam does.
Long before there was pen that can draw in the air
