Okay I’m at a serious loss here, no matter what I do and what temp I use to melt my base, it develops a film and turns out rubbery EVERY time. I’ve done 30 second bursts in the microwave, 30 second bursts on half power, a double boiler, a double boiler on the lowest heat setting, I’ve reduced my additives to practically nothing, and no matter what, by the time it’s able to fully melt, there’s a film on top and the end product is just way too firm and rubbery. What on earth is the problem, and how do I fix it??
