I want to burn plastic for molding and experimental stuff. But I need to know which plastics are safe to burn and which are meltable. I know there is 1,2,3,4,5,6 and 7 but what are they really called and which are safe to burn and also meltable. Thanks in advanced.
All plastics will release poisonous fumes when burnt. The way the industry does it is by heating it up very slowly to a precise temperature where it starts to turn into a liquid, not a gas. I've used acrylic before to make some cases. Its a hard plastic and can be heated with machines to bend and shape to ones desire. It is always a good idea to use a respirator or be in a well ventilated area because the plastic will give off fumes
