Cutting, Testing, & Stamping Soap

Trying to decide on the size and shape of each bar of soap has been a back and forth process for me.  I initially wanted a tall, wide bar with a slightly textured top.  I recently changed my mind.  I think the tall bars are harder to hold.  So I’m now cutting fatter bars that are all at least 4 ounces in weight after curing.

After my soap has gone through the gel phase and returned to room temperature (about 18 hours), I remove the soap from my silicone molds and prepare to cut, bevel, and test the batch.  I also stamp any bars with my logo that do not contain botanicals (like peppermint leaves, etc).  I took some photos today while cutting my Rosemary Mint and Plain-Unscented soaps and thought I’d talk about each step just a bit.

I use a single wire soap cutter that I found on Etsy (Bud Haffner – Bud’s Woodshop).  I really like this soap cutter and the ability to adjust for size.  Especially since my tops are not uniform, I usually vary the thickness of each bar to keep the weight over 5 ounces.  As long as I keep the wire really tight and don’t have a lot of air bubbles from my hand mixer, I get a nice smooth cut.  It’s easy to clean and very easy to replace the wires.

After each bar is cut, I bevel every side with a plain old vegetable peeler.  I even bevel the edges on the contoured tops (I really hate sharp edges on my soap).

At this point, I go ahead and do a quick pH test on several bars.  I use two different kinds of pH strips (both strips measure between 1 and 14).

The last thing I do before putting the bars on the curing rack is stamp them with my logo.

I had a beautiful stamp made by Lasercutz in England (for a really good price, too).  My logo is fairly dainty, so I had no idea how it would look stamped into the soap.  I couldn’t be happier. The stamp itself is very easy to use.  I’ve tried stamping at different phases of the 3 to 4 week cure, but right after the bars are cut seems to be the best time for me.  I get a nice deep impression with no soap lifting or sticking to the stamp.

Thanks again to my Mom for painting such a beautiful and unique logo for my soap company.  I love how it looks stamped into my soaps.

Thanks for stopping by!
