|My pencil-line Eucalyptus Clove soap|
I was new to all of this pencil line stuff until recently. I had seen it done, but had never tried it myself. What is a "pencil line"? See the thin brown line between the two layers of my soap? That's a pencil line. Such lines are made by dusting a layer of mica, cocoa powder, poppy seeds, ground spices, ground coffee, charcoal powder, etc., in between soap pours. When the bars are cut, the line runs through the width of the soap, looking like it was drawn with a pencil.
One of my mom's favorite soaps is scented with a blend of eucalyptus and clove essential oils. When my folks came to visit last month, I gave her the last of my Eucalyptus Clove soap. Knowing how much she likes it, I made some more since I was plumb out. I figured it would also be a good time to try out the pencil line.
Because this was my first time playing with this technique, I kept things simple and did not color my soap or try to do anything too artsy so I could focus just on the pencil line. I thought about using ground cloves for my line, but decided against it, worried that it might be too scratchy or possibly a skin irritant. So I used some Cappuccino mica instead.
I made my batch of soap as usual and brought it to a medium-thick trace. I poured about half of the soap into my mold and then scooped a bit of mica into a tea infuser. (Any small sieve will also work.) To make the pencil line, I gently tapped the side of the infuser while moving it over the soap, creating a thin layer of mica. (Take care not to make too thick of a layer - the soap can separate if too much mica or powder is used. You just want to barely cover the surface of the soap.)

By the time I was done fooling around with the mica, the remaining soap in my mixing bowl had set up quite a bit and was thick. The first layer was poured at a fairly heavy trace, so I felt confident it could support the next layer. I poured the second layer over the back of a spoon so that the soap wouldn't break through the first layer, disturbing my mica line.

A few days later, it was time to cut. Here's a tip for cutting soaps with a pencil line - turn the soap onto its side and then cut it. If you cut top-to-bottom, you'll drag your line through the soap. Cutting the soap on its side keeps the line nice and crisp. And also wipe your blade clean after every cut. (This tip also works if you've got something like calendula, oatmeal, seeds, jojoba beads or whatever sprinkled on top of your soap. Ever cut your soap and had the stuff on your decorated tops drag through the soap, making grooves? Try the side-cut to avoid that.)
So, I took the soap out of the mold so I could line it up with the edge of the mold and the cutting notches. I used my cutter to mark where to cut and then did my best to make a straight slice with a chef's knife. I am the worst at freehand cutting, but I did okay with my notches marked off. The bars aren't as uniform as I would like, but they're not bad.
And how thrilled was I that the soap didn't separate when I cut it? Very, that's how. I worried I was a bit heavy-handed with the mica in parts, but I guess I did all right.
The pencil line technique is definitely something I want to play with again. I want to experiment with bringing the line higher up the soap. And while I like how straight my line turned out, I rather enjoy some of the soaps I've seen with imperfect pencil lines - lines that slope a bit or have a couple of small ridges in them. Perhaps I need to work some texture into the soap layer before dusting the line to achieve that effect.
Do you like pencil lines? Ever made one? What are some of your tips? Do you like perfectly straight lines, or do you like lines with a bit more character?
