Using Thermoplastic in Jewelry Making
by Kylie Jones
Thermoplastic is a very versatile material that is a great addition to your toolbox. It is a plastic that softens and becomes pliable when heated and hardens with a fairly smooth finish when it cools. It can be used to hold elements like rings and other settings so you can work on them more easily. It can be used to make handles for tools that fit perfectly into your hand. It can be molded and shaped and then remolded again.
Instructions
You can buy thermoplastic in different ways, the most common are small beads (Jett Sett) and sticks (Thermo Loc). The products are different, the beads are heated in water and the sticks are heated with a heat gun or microwave or other heat source. I use the beads and simply add them to hot water, let it stand, the beads start to melt together and become translucent and pliable.

It is hot when you pull it out, it can be carefully moulded into whatever shape you need. You can keep dipping it in the hot water to soften the plastic until you have the desired shape. To recycle just pop it back into hot water and it will become pliable again.

Each product will have information on the best temperature and method to soften the product. Thermoplastic does get hot so you need to be careful handling it. I use a spoon and a glass jar that I only use for this product and not for food. If you are making handles or steel tools and are using thermoplastic softened in water be careful to dry the tools thoroughly to prevent rust.
