Rendered some mutton kidney leaf fat. Ended up with nice pure white firm tallow. I made up some experimental B.P. lubes I hope to try out this Spring. I didn't come up with this one..1880 formula from S&W & Maynard Co. 3 parts tallow 1 part beeswax. This is a nice smooth lube about like SPG in hardness..readly absorbs into skin when rubbed between fingers. Next, using same ratio as above, I added 1 part castor oil..this is even softer..and greaser, yet shows no tendency for oil to bleed..I thought this would make a good grease cookie. I might try adding 1 part anhydrous lanolin to this one. Had always wanted to try Bayberry wax..U.S. army used it in 1873. This is an extreemly hard and brittle greenish colored wax. I used a razor sharp wood chisel to cut chunks off wax block..and ended up with more fine powder and particles than chunks..the stuff is that brittle. When I first started working with it I figured only a small amount would be needed on account of it's hardness..but H.M. Pope was using it 1-1 with beeswax. I was using a beeswax base, anhydrous lanolin & castor oil. I soon found I could also use equal amounts of bay & beeswax. The bay wax didn't really impart any noticible hardness..but it did make the mix VERY smooth in texture. I ended up making samples of tallow, beesewax, baywax, anhydrous lanolin and castor oil...one with all ingredients..others in combination of one or more..all however contained tallow, beeswax & baywax. Trying out all these combinations should keep me from getting bored for at least a year!
