I usually use Golden Wax Melt for my wax tarts, but this time I just wanted to try something different. The paraffin is a very hard wax to use. I ended up using my knife to carve off the amount I needed to test it. Well you do not need very much fragrance to make the melts , that is a plus. The cold and hot throw is good too. The only con is that the fragrance scent is mild after that and eventually disappears. I would give it maybe 8 hours. I am used to my melts' scents lasting a few days. I prefer the Golden.and will stick with it.
