I made a column swirl soap in a silicone slab mold yesterday and today I wanted to show you how I cut slabs. If you’re lucky enough to have a slab mold with lines or dividers then that makes it easier. But if you don’t…it can be a bit of a challenge. Here’s how I do it.
I first trim the edges by running a knife along them.
I like to use a Fiskars 3″ x 18″ see through ruler when I cut soap. You can find them in the sewing/cutting section of most craft stores. I use the ruler to make a cutting grid to make cutting easier.
My soap slab is about 12″ x 8″ and I want to cut 2″ x 2″ pieces. Lay the ruler on an edge of the soap so that it measures out 2″ and score the soap with the tip of a knife. Keep doing it all of the way down the slab in one direction and then the other.
Once you score the first line…move the ruler up to where the two inch mark is on top of your first score and score another mark two inches from the first one.
Once you score up one way…score up the other way.
Once scored…cut it using a knife. I like to drag the tip of the knife through the soap instead of using a chopping motion.
