Hi kmommy, remember me? it's been a long time since I've been here and there's lots of new people around but it's good to see some familiar 'faces'!!! anyways, after all these years I also have done some tests on blends and they are just so easy compared to the 100% soy like always! of course being too conscious but a little p will not hurt right? So based on a lb of wax, I add only 2% or 14oz + 2oz, just very little enough to make it smooth and still creamy. (i that the right percentage?? not sure!!lol!!) As for sooting, it still soots anyway due to some oils, there really is no such thing as soot free, but of course it will not blacken your walls like pure P! as for the 135, yeah, I must agree it is very disappointing, that has always been the problem with that wax!!! hth... ~marie:)
