You can always nuke the plastic to a semi cooked state and pour into the pot to speed the cooking time up. Pots do take longer to heat plastic, but less likely to burn. Once the plastic reaches 350 degrees, turn down the thermostat and record your temp until you're at 330-340. This is when I add my glitter. With cooler plastic, the glitter is less likely to curl or lose it's color. Some glitters do this, some don't, some purples are known for this. This can be applied to microwave cooking too. As you remove plastic from the pot, watch your temperature of the plastic. You have less volume and the heating element doesn't have to work as hard and could eventually burn the plastic. After you've been doing it awhile, you can watch the consistency of the plastic and tell, or if it's constantly smoking after the cooking stage and you have removed a lot of plastic; it might be too hot. As stated before by HT, get a stirring system. It will help keep the plastic cool, it should help to keep glitter and salt suspended evenly throughout plastic and the bait making process. Meaning you should not have a lot of glitter/salt in one bait vs another bait, they should be fairly close in weight.
