Since I have everything out to weigh, I just multiply by however many batches I want to make up. Ex... 4 x each ingredient. I melt my hard butters or oils first and then add my liquid oils to that in a large container with a lid. Then I measure 4 x my water add 1 tsp. TD per pound of oils and 4 pinches of silk and stir well. Measure 4 x the lye and add to water in a pitcher and transfer to bottle with a screw on lid when cool. To make a batch, just stir master batch and measure out for 1 batch of oils. Shake lye water and measure for 1 batch. If I know the FO behaves and doesn't discolor I add it to the oils. If it is going to discolor, I take out for the swirls and then add FO to the main batch. I saw a video where the person barely mixed (about half the time I did) and poured out for the swirls. She had plenty of time to play. This explains everything about the molds and liners: http://www.craftserver.com/forums/showpost.php?p=772936&postcount=34 http://www.craftserver.com/forums/showpost.php?p=772937&postcount=35
