eFish, I use an Electric Burner (probably not a Hot Plate, aka Electric Skillet) with a Stainless Steel 1-quart Saucepan/Pot with a thick bottom. My Electric Burner is basicly 25% of an electric stove/stove top, coil-style element. If I was on a PC I'd go to Amazon and post links of the pieces I use. I can have a new Burner and Pot, exactly as I have now, shipped to my door for about $41 and change, from Amazon.
I bought a Hot Plate for this thing once...it hit the lawn the 1st time I turned it on.
In my trusty Pot on the Burner, I toss in my cut-up scraps, stabilizer, softener if any...any colorant and HDA goes in after melting...I let it heat up then I start pushing the mass with the stirrer. If I had a camcorder I'd video my method. Microwave has no place on my bench.
It may have been Justin9 that turned my attention to a Pot 'n Burner...I think he uses a Cast Iron Pot. I fought through many Issues when I started, and I started with a microwave...I've been there, too...and what I know now, is why I advocate what I advocate...man, Yawl need to try this.
It's simple, cheap, safe, space-saver, holds heat very well, easily adds more heat to a cooling mix, avoids heat spikes possible with microwaves...lots of Pro's.
