Step 2: Melting Bags
Set your deep fryer to 300*F and monitor the temperature with the thermometer. Make sure you continue to stir the wax because we do not want any hot spots that could cause the wax to ignite.
Once you hit 300*, begin adding the plastic bags, one at a time. It helps to cut them into strips so that they wont ball up, but I don’t have any data to support a specific way just yet. The more your stir this mixture, the faster the bags will dissolve (Just don't get too crazy, you could introduce a lot of air into the wax). Continue adding bags until they won’t dissolve any more. Most of the plastic should have dissolved, leaving just a few chunks left. With LDPE this is usually a 25% mixture, whereas HDPE bags are around 15%. Stay patient, this process can take a while.
