Since your hard oils are only Coconut and Palm and they melting point of each is 76F and 95F and freshly made lye solution is around 180F-200F, I can only assume that you mixed ALL your oils together and then poured in your lye solution. Not only would that had dropped the temperature of your lye solution, but that heat is being applied to ALL of your oils equally. Next time, JUST measure out your Coconut and Palm Oils, then add your freshly made lye solution and STIR. Your oils should be melted in no time at all. THEN add your soft oils. Check out videos by Jen w/A&N's Suds-N-Such & BeScented and recently videos by Julie w/Ophelia's Soapery; both are using HTM, though Julie recently switched to Cocoa Butter wafers. Jen will stick blend towards the end of the melt, Julie pretty much just hand stirs. I've tried it a couple of times and I use Coconut and Palm Oils, Cocoa and Shea Butter. I freely admit that I shred my Cocoa Butter (I use my vintage Salad Master) to cut down on melting time, but it's still the ingredient that takes the longest to melt.
