One of the keys to rendering bear fat, especially if you don't do it in water, is LOW heat, the lowest possible. Once rendered and stored in jars or containers, liquid oil will separate from the white grease. The lower the heat used in melting the fat, the more liquid oil produced. It is this oil that makes such an excellent patch lube that stays soft even in cold temps. I wouldn't mix with beeswax for use in blackpowder muzzleloaders, use it straight. ...Where I DO mix it with beeswax is for use as a leather treatment and waterproofing. It is a very useful substance!
