Bottle caps come in a wide range of colors and make beautiful items. Melting temperature is +- 190 degrees Celsius. Melting and pressing were done in a homemade heat press. A good idea for a home business (a fume hood is essential). Don't try this without familiarizing yourself with the melting properties of plastic; it's dangerous to your health!
