hey bw. about the double boiler method. that's what i use. i guess i like the way i can control it, but i also "reprocess" it a few time, to try and separate scrap out. each time it is melted the wax will settle in layers. i use a tall/narrow can, use something you don't mind trowing away or using for just that purpose. if you strian it with a cheese cloth, you should wet the cloth. i remember the first time, i was cleaning wax wax from all over the kitchen. the book "beekeeping for dummy's", has a few suggestions. john vivan's "beekeeping", tells about processing wax more. he even has info on making your own foundation press.
