melting hdpe plastic health concerns?
I want to do some vacuum forging (from another instructables) and i was thinking about melting milk jugs for it. if i heated them with a blowtorch would it emit bad fumes into the air, as long as i didint burn it? I would do it outside and im 13 so i dont want to mess myself up. if it does make fumes, would a respirator with a fine filter stop them?
