I got the white electric tart warmers from BC and I have a problem. I first noticed a note in each box that talked about how to use it for EO's, with water and then a few drops of EO floated on top. I tested the temp with as much wax as I could get into the thing and it went over 200F, something like 215F if I remember right. I dont really feel like selling them for tarts because I think this is too high of a temp for ANY kind of tart. Side note, the bath and body store in the mall where my show is has a oil burner with a tealight and the burner had tons of smoke from the oils being too hot. I guess they have the oils to use in them now, I smelled cinnamon... burnt cinnamon. LOL Anywho, I have a few light bulb tart melters that keep the temp at 160F which I like much better than over 200F. Any ideas on what you think is the perfect temp for a tart melter? Hey, I just thought of something, someone was talking about a deal where a candle melt pool should not be over 175? on a 4 hour burn..? Sounds like maybe that would be a nice temp for wax to stay at.
