I'd just whack a bar in half and add three level measuring tablespoons of ester, shave the Ivory with a knife and heat it 'till it liquifies and pour it into a cool container. I didn't want to fry it so mine had a big patch of foam left floating in it when I poured it out. Be careful, it goes liquid quite suddenly and the temp looks like it will skyrocket as the soap completes its phase change, not sure the K2 can take much more than absolutely necessary to melt the soap. The foamy patch didn't amount ot much when it cooled and I just kneaded the grease into a big ball when it reached room temp.
This does take a toll on components. I wore out a match-prepped lot of 200 .30-'06 cases last year screwing with this, and it takes a lot of shooting to wear them out with 2k fps loads. Now I'm looking at a hundred .30-30 cases that are starting to get sloppy primer pockets and a few tight necks. Might have to buy a gas check tool before too much longer, I cracked into the last thousand about a week ago, thought I had more but turns out that other box was full of .35s. Maybe that will be a good excuse to bed the buttstock on my .35 Remington and start playing with it, got a really sweet 45 2.1-designed boolit mould for it made by BABore with that huge, honkin' single square lube groove, it's been a really good test of lube jettison qualities in the past.
