I actually don’t know. I want to try it out and see what happens. Will it change color or like melt away? And by burning I mean putting the engraved side over a flame like a lighter or stove fire.
I would assume it would turn black. However, there is a chance it will turn orange/red, because when you engrave metal at too hot of a temo, it causes the engravings to be orange rather than white.
you can find wood burners at a local art/hobby store. I have done it before. Tmbr has the eh which was lazer engraved which burning can give it that effect. It darkens the wood in the places you bring the burner over. The burner is kind of like a hot pencil.
