Forms: Thermoplastic comes mainly as small beads (like Jett Sett) or sticks (like Thermo Loc).
Heating: Beads soften in hot water until they melt and become translucent/pliable. Sticks are heated with a heat gun, microwave, or other heat sources.
Usage: Once softened, you can shape thermoplastic however you want. Keep dipping it in hot water to soften it more as needed.
Recycling: Pop it back into hot water and it becomes pliable again for reuse.
Safety: It gets hot! Use tools like spoons and dedicated containers to handle it safely, and avoid mixing these containers with food. Also, if using thermoplastic on metal tools, dry them thoroughly afterward to prevent rust.
The pictures you mentioned sound like great examples especially using thermoplastic to secure a bracelet on a dowel for stone setting, or making custom handles for bezel rockers.
Have you tried making any custom handles or fixing tools with thermoplastic yet?
