First is a heat source to melt your plastic. Perhaps the easiest way to start will be a microwave. Use a pyrex cup to heat the plastic in. There are lots of threads on this here on this forum and a search will give more detailed answers on various aspects of the pouring hobby. Just be warned before you start that you will get addicted and will not save money as there will always be a new mold you "need". Working only with remelts only will soon be limiting as well and you will start buying virgin plastisol, coloring, glitter and various additives. Don't hesitate to ask questions as this can shorten the learning curve. Good luck.
