Edison wax formula

[kropton]

Hi
I still trying make a hard edison blank cylinder.
I added carnauba to beeswax - cylinders are good hardness but cracking during the molding

Does this formula is good :
25% stearic acid
25% Ozocerite [can I replace it by parafine ]
50% beeswax

Is Chuck and I the only Edison wax formula experts in this forum?? Making a good recording wax is a very complicated thing, there is no simpleness about it. If it was simple all those on this group would be sucessful at making there own blanks. I have authored detailed articles on wax formulations in the trade journal "In The Groove" One on a formulation I use, on on Edison experiments, and another on Columbia records. 100 parts stearic 25 parts ceresin or parriffin, and 25 parts carnuaba is a good wax for testing purposes, and this formulation is from 1888 for the white perfected records. Actual metllic soap used to make production brown wax, is dangerous to make, i have had some horrible burns. Heat stearic to 360F and make a seperate solution of aluminum dissolved in caustic water, add to the stearic, let it cook until all bubbles stop coming up, it takes a minimum of two hours for this to happen, it may take as much as a whole day, if you are making hundreds of pounds. When this is stopped add ceresin wax, or parrifin, and heat about a half an hour at 450 degrees, until a soy sauce brown. It may catch on fire at this point. let this wax cool overnight, and mold the next day. trim and shave blanks the dau after molding, and then let set for 30 dalys to cure, and finish shave. I will let you figure out the proportions, it takes hundreds of experiments to arrive at the right amounts, and things must be within a hudreth of a gram.
