Step 1: Materials and Preparation
Make sure you remember that all materials you use for this project must be safe for baking at 450 degrees. Prepare your piece by removing all gluey lids or stickers, or rubbery gaskets, or anything else that's gooey and not allowed in the powder oven. Then clean it with soapy water, and let it dry thoroughly.
You'll probably want to work with several (3-8?) pieces when you first start because there's a learning curve to the process and it also saves time to work in batches. Further, if you're going to LASER or paint your coated pieces later, you'll need extra pieces for test strips and continued runs. You DON'T need to work only with jars: any kind of glass should work as long as the foil will attract the powder through the glass and you can work with the pieces throughout the process of coating and moving in and out of the oven.
What you'll need:
> Several Glass pieces between 4" and 20" in diameter. (rough estimates. it just has to fit your machines and be movable.)
> Hot soapy water and sponge or rag to clean materials.
> Powder coating materials, supplies, equipment, including powder oven.
> Heat resistant tape- Have about 5-30 feet for a project because you want to use it liberally.
> Aluminum foil. have at least a quarter of a roll to a whole roll for each project just so you don't run out.
> Conductive work-holding device, either hanging or resting, able to be transported to the oven and back.
> Gloves to transport the hot materials
> A clean rack or surface to cool the materials once out of the oven.
> optional: Wrapping paper or something to transport your piece out of the shop after you've coated it.
