I wasn't able to get Oxygen to blend in J50. That's probably the fourth FO from as many suppliers that's given me that problem. I don't blame anyone for it. Every FO isn't going to work my wax, or any other wax. It might not blend, it might turn the wax an ugly color, it might not throw... That's the reason for testing. If an FO doesn't work out for me in candles, I try to find another use for it, or sell it.
