I use a lot of wax and honey in my soaps, I save the cappings wax for soap. As far as extracting, I was taught long ago to shake the frames over newspaper if it isn't capped - if it doesn't splatter on the newspaper, it's good to go. So far I've had no problems with it. No refractor, but I do have a nice Maxant extractor in the cellar, when hubby buys, he buys big!
