Tutorial: Using Mica to Stamp Cold Process Soap (+ a New Custom Soap Stamp!)

You know how much I love my custom soap stamps! They are a great way to add a unique flare to cold process soap and incorporate your branding into your naked (unpackaged) soap!

Can it get any better?

Of course! You can give it a real touch of luxury by using mica to stamp cold process soap. It creates a glittery or shimmery impression! Here’s a quick photo tutorial on how to do just that…

Using Mica to Stamp Cold Process Soap

PREP WORK: Make sure your stamp is nice and clean. Use a toothbrush to scrub out any soap bits! Sprinkle out some mica on piece of paper. You want a nice flat surface with a thin layer of mica, so that the mica does not get into the crevices of the stamp.

GET STARTED: Place your stamp directly onto the mica, and press. Think of it like using a rubber stamp with ink on paper. You want to place the face of the stamp directly down on the mica, and get a nice coating on the face. Take care that you aren’t getting mica in the crevices of the stamp!

Check the distribution of the mica on the face of the stamp, and tap any excess off.

STEADY NOW: Place the stamp on the face of your bar of soap, being careful not to move the stamp once it comes in contact with the soap. If you move it around too much, you’ll have a lot of mica to clean up!

Once you have your stamp placed, use a rubber mallet to get a nice clean impression.

MAKE IT PRETTY: There is always a little bit of excess mica that flutters out from the stamp onto the rest of the bar of soap. You can clean it up really easy!

Spray the face of the bar of soap with rubbing alcohol or distilled water, and use a microfiber cloth to gently wipe off the bar. You want to barely touch the cloth to the soap. Or you can use a cotton swab! Another option is to spray the cloth and wipe the face of the soap, instead of spraying the bar itself.

Spritz the soap with rubbing alcohol or distilled water to remove excess mica.

SHIMMERY BEAUTY: Once you’ve gotten it all cleaned up, your soap is ready to cure. Voila! Shimmery and beautiful stamped soaps!

Did you notice anything about the stamp?

Oh, yes, I got a new one!

One of my previous students Tara told the fabulous owner at Jet Stamps about my obsession with cold process soap stamps. (Thank you, Tara!!) I sent Brett my logo for Gratitude Soapery and he whipped up a stamp super fast and got it in the mail.

BONUS: Jet Stamps is in Asheville, North Carolina so I had it in two days flat.

It arrived well packaged. I was totally itching to put it to work, but alas, I was a little busy with Central Soapers Workshop.

I finally had time to play with it this week! As you can see, it works great!

I didn’t have any issues with sticking. (Some stamps have too much of an angle on the engraving, so it sticks in the soap…) I would have liked if the engraving was a tiny bit deeper (and when I communicated that to Brett, he’s on it to make those changes for soapers!), but I still got a nice impression.

The soap in this tutorial was about 36 hours old. I also used it on a soap that was about a week and a half old, and while harder to stamp (like any stamp would be), I still managed a clean impression. The stamp feels sturdy and cleans up well with a toothbrush, like my others.

A little bit about the fab guy behind Jet Stamps…

Brett originally got his start using his milling machine for his wife’s jewelry, and other random projects. He then started doing clay stamps (he’s involved with Empty Bowls, by providing his stamps at near cost for pottery made for the project), and is now happy to offer his services to soap makers.

(Plus, he makes some really cool topographic art with his milling machine.)

Disclosure: I did receive my stamp as a gift from Brett. However, my decision to blog about it and the opinions provided are my own. I love supporting other makers, especially those who have a quality product and are making a difference through their biz. Y’all know I don’t hold back when it comes to opinions though! 😉

  1. Your soap and stamp look awesome, thanks so much for sharing! I’m in the market for a new stamp…will have to look Brett up! Thanks again!

  2. Yay!! I am so happy you shared this tutorial, it really helps me with my stamping. I was thinking the same thing about my stamp. I loved it but wanted the impression to be deeper, so thank you for sharing your thoughts with him 🙂 Also, I was impressed with Brett’s customer service. He was very quick to respond to my emails, and I can’t believe how fast I got my stamp! Thanks Kenna for all you do!

  3. I recently purchased my first custom stamp and it was from Brett! Awesome stamp, works great, looks great and Brett’s customer service was excellent. I would recommend him to any other soapers looking for stamps! 🙂

  4. KENDRA, YOU NEED TO CHANGE YOUR PHOTO. IT IS CLEAR IN THE PICTURE THAT YOUR DENTAL WORK IS FUCKED ON THE LEFT SIDE OF YOUR FACE. IT’S KIND OF A CREEPY PICTURE.

  5. Hey Kenna! I actually live in NC and I am looking to purchase a stamp from Jet, but I am not sure which stamp would be the right fit all of my soaps range in weight from 5-6 oz. 1 inch thickness and about 3- 3 1/2 inches accross. I really like the stamp size you have what would you recommend?
    Thanks!

    1. My stamps are mostly 1″ or less tall, and up to 3″ wide. 🙂 Brett @ Jet Stamps can also help you decide what you need for the stamp to work properly with soap, I did a bit more testing for him on using the stamps in soapmaking to make sure he’s putting out the best product he can. He’s a very awesome guy!
