I love home fragrances, which is why I make my own scented candles. During this past holiday season, I got curious about ancient scents, such as frankincense and Myrrh (arguably a bit ironic as I am Jewish.) To indulge my curiosity I got some of these (the natural resins), a burner and some charcoal discs. (You use these by placing some of the resin on the heated disc.). I have learned a few things that fascinate me; 1)The method of use (see above) 2) There is evidence of their use, dating back to ancient Egypt. 3) There are more than 2 dozen types of frankincense, coming from different species of tree. Does anyone else here have any experience with these? Do you have favorite suppliers or varieties of F & M?
