HI I use a roaster and the only tip I have is to cut your slab of wax into smaller pieces. OH and check the temp. these things are not real accutate. I have to set mine at 230 to get wax that is 200. Personally I love mine I put 2 slabs of wax in it at a time. It does take awhile to melt the first time. However, after you have melted it once. The remelt goes fairly quick. Goood Luck, Tammy
