This is how I do it. I use the bigger production pot.
If you wipe down the inside of the pot with scent before you start it will help with the clean up afterwards, sorta acts like a non-stick surface.
1. Heat plastic up in the microwave and while the last 30 seconds of heating the plastic, plug the pot in on the lowest setting, (this gives the pot a chance to heat up but not to hot to scorch the plastic)
2. Pour the plastic in the pot and increase the heat by 1 setting every minute till it gets to setting 6 or 7 (you definitely need a candy thermometer to regulate the heat, there is a hole that goes between the outside and inside of the pot, slide the thermometer in that hole)
3. After the temp hits around 300 I add my flakes then pour away.
With the bigger production pot the pour spout hole is bigger (3/16)
so it will not clog up with bigger flake I have used .062 flakes with no problems.
Hope this helps
