Explanation:

we are talking in units of degrees F, then your HDPE/LDPE will start melting at ~275 F (depends on grade and type). Fumes from melting are not especially bad, but this process needs to be well ventilated anyway. The fumes can cause irritation (according to DOW Chemical).

Explanation:

What are some of the dangers in trying to melt HPDE or LDPE? I'm trying to make carvable/machinable wax.

I'd like to make my own carvable/machinable wax. Bricks of the stuff are sort of expensive. The recipe I've seen on a few DIY sites suggests that you mix about 5-10% LDPE or HDPE with parrafin and you're get a very hard wax suitable for carving and machining.

And, you know, that sounds great. I've got like 20 lbs of paraffin lying around, and HPDE/LDPE is just a matter of collecting old food containers.

It's the whole "melting plastic in a controlled fashion using home equipment" part that I'm worried about.

What are some of the dangers, here? Obviously molten wax and plastic are plenty dangerous all by themselves, with plenty of potential for bad burns. But should I be worried about toxicity?

Eitherway, "The Plan" is

Get some kind of deep fryer or similar device that has temperature control.

Kitchen thermometer
