Project

Heart-Shaped Soap

Stamped soaps, inspired by candy conversation hearts, are great gifts for friends.

Introduction

We used a 2-inch cookie cutter (1 inch high) and 2 1/2 pounds of glycerin soap-sold at crafts stores-to make 16 hearts.

Put in cellophane bags tied with tags; adorn with glitter.

Materials

  • Nonstick 9-inch square pan
  • Heart-shape cookie cutter
  • Glass measuring cup
  • Glycerin soap
  • Bench scraper
  • Soap colorant or food coloring
  • Spray bottle filled with rubbing alcohol
  • Cutting board
  • Needlenose pliers
  • 1/8-inch metal letter stamps
  • Masking tape

Steps

  1. Step 1

    Depending on your equipment, yields may vary. To determine how much glycerin you'll need, fill pan with water to 1/4 inch below height of cookie cutter; pour water into measuring cup. Record amount; discard water.

  2. Step 2

    Cut soap into small pieces with bench scraper; fill measuring cup. Microwave on medium heat until melted; stir. Add soap and heat until you've reached the water amount. Add colorant; stir. Pour liquid into pan. Spray with alcohol to eliminate bubbles.

  3. Step 3

    Let harden at room temperature, 2 hours. Freeze 10 minutes.

  4. Step 4

    Turn upside down onto cutting board. Create soaps with cookie cutter; pull cutter out with pliers if it sticks. Tape stamps together to form words, and imprint on soap, applying light, even pressure.

    Be sure you do not use Ivory soap (even leftovers) in the microwave! It puffs up to about 100 times the size of the piece you put in there. This is the only soap that does this. I use it in science experiments.
    Thanks all for your helpful comments.

    Hey Martha. This is an excellent idea. I will be making these as favors for my daughter’s spa party.

  • 25 Oct, 2012

    I just love those soaps ,for the past 20 years ,I give them away for any special occasions,even Halloween !
    The only hard time I had ,was to find THE high quality fragrances but I did: EXOTICFRAGRAMCES.COM ,over 1500 fragrances oil to choose from and great to make scented lotions .My favorite is "Spanish lemon verbena ".
    Happy soap making !

    Alcohol is great for removing bubbles. And it's about the only thing that will hold layers of soap together, if you choose to make a layered soap. The best fragrances I've come across are from www.wholesalesuppliesplus.com. However, you can find almost any fragrance you want on-line if you just google fragrance oils and the scent you want.

    An old nylon knee-high is great for polishing your soaps.

  • 21 Jan, 2012

    If you buy soap colorants ( I purchase the majority of mine from www.goplanetearth.com), there are colorants that will make glycerin soap opaque and colorants that will keep them jewel-tone and clear. It all depends on the type you buy.

  • 21 Jan, 2012

    I purchase most of my oils from www.thesage.com. There are lots of wholesalers out there, but I think their prices are the most reasonable. Also, if your soap turned to paste, you probably heated it for too long. 30-second bursts, one at a time. I've been making melt and pour creations for several years, and have finally gotten good through lots of trial and error!

  • 21 Jan, 2012

    Next time, try a silicone pan! Also, for the best melt and pour soaps, try www.goplanetearth.com, or www. wholesalesuppliesplus.com. More reasonably priced and much better quality. I always try to get the ultra-clear glycerin soaps.

  • 13 Aug, 2011

    I bought the glycerin soap from Michaels, and I made these lovely soaps. But when I used it to wash my hands, it made my hands feel weird. Like for normal hand soaps, it moisturizes your skin, leaving it feeling nice and clean. But these didn't so I just tossed them into the garbage. :(

    I'm not sure if I'm purchasing the wrong type or what. Can someone please help me!

  • 4 Feb, 2011

    To remedy sticking in the pan, spray it first with cooking oil. It will not alter or harm the soap at all and the soap should come right out with ease.

  • 27 Feb, 2010

    Help! I couldn't get mine out of the pan except through immense digging with a knife.

  • 7 Feb, 2010

    I would love to see all your Great questions answered!!!! I have the same thoughts.:)

  • 26 Jan, 2010

    I have a muffin pan for heart shaped muffins-do you think I could just mold them instead of cutting them out ?

  • 20 Jan, 2010

    Couldn't you skip cutting them out buy putting them in a silicone heart pan?

  • 8 Feb, 2009

    So we (two boys

  • 5 Feb, 2009

    Where have people purchased soybean oil and or palm oil when they make soaps?

  • 3 Feb, 2009

    Oh, and I forgot, I polish my soaps with a clean t-shirt to remove fingerprints.

  • 3 Feb, 2009

    Soap fragrances and colors can be found at most craft shops. Walmart discontinued theirs about the time I started making soap, of course. There are oodles of online suppliers, too. If you use oils from your kitchen be aware that vanilla extract will turn your soaps brown and mint extracts and oils will burn tender skin. Food coloring will stain skin and washclothes, but will usually wash away.

    Years ago I had an elderly friend that used to save all the small pieces from bars of soap. When she got a gallon jar full, she would melt them down and pour them into molds. She aged them for a few weeks to harden them so that they wouldn't "wash" away.

    To everyone who is as tired of MUMTAZ as I am: please report those types of postings for what they are: SPAM. I report them as inappropriate every time I see one. If you do too, maybe we can curb it from showing up on Martha's message boards.

  • 2 Feb, 2009

    this is a great gift idea this coming hearts day. It is easy to make with the help of the video. thanks. I will make it and give it to my friends.

  • 2 Feb, 2009

    That looks like a fun thing to do with the kids.

  • 2 Feb, 2009

    mumtaz - give it a rest. You can find the letters at Michaels, JoAnns and Hobby Lobby. And probably at most large craft stores, as well as online. You can spray the cookie cutters with Pam to help them slide out of the soap easier. I love the idea of using alphabet pasta - I will give that one a try. You can use any old soap, and the little soaps you get at motels. They melt easily in the microwave, just watch it, and you can mix them together.

  • 2 Feb, 2009

    where can I find the little typographer's tools to print on the soaps?

  • 2 Feb, 2009

    To make it solid in color, Martha must have used white glycerine instead of clear.

  • 2 Feb, 2009

    This looks so adorable--I've made soaps with my kids before and we just used regular food coloring from the grocery store and it worked great! We also melted the glycerine in the microwave. Can't wait to try this one!

  • 2 Feb, 2009

    Where can you find the letter stamps?

    Also what did Martha put in her glycerin to make hers solid in color?

  • 2 Feb, 2009

    I don't know that body spray would work - the alcohol may make it not bind correctly. I'd try it on a small sample.

  • 2 Feb, 2009

    This sounds like what I want to make the Grandchildren for Valentines Day! Great idea,thankyou,

  • 20 Jan, 2009

    I sometimes make soap. You can buy fragrances in craft stores that are made to go in soap. You may be able to use the calgon if you just add a few drops to the mixture of dye and soap. It is like the dye, you just pour it in.

  • 19 Jan, 2009

    I am wondering how to put a fragrance in these, does it matter what I use? I want to use a Calgon body spray....

  • 11 Jan, 2009

    I wish to make these darling heart soaps for all my friends, and i don't want to go out and buy glycerin. Does anybody know if you can use bars of soap from hotels and name brands, or will there be chemicals in that soap that can react badly in the heat of the microwave???

  • 14 Feb, 2008

    i used alphabet pasta for messages on mini hearts and it worked really well.

  • 9 Feb, 2008

    How do you get rid of the fingerprints on the soap after it cools?

    Instead of a cookie cutter, try a heart-shaped silicone cupcake pan. The sides aren't vertical like a cookie cutter, but the slight flare is attractive and they are much easier to remove.

  • 7 Feb, 2008

    I've been using alcohol in a spray bottle to get rid of soap bubbles (and hand disinfection) for the last 15 years!!! It works GREAT!!! Especially to get rid of bubbles in bottles you're trying to rinse out and hand washing your clothes in the sink. Try it, it works like a charm!!!

  • 7 Feb, 2008

    Try looking in the leather crafts section at Michaels.

  • 7 Feb, 2008

    Where can I find metal stamps?

  • 1 Feb, 2008

    metal stamps - i am getting the .25 inch though. the 1/8 inch seems too small for the size of soaps that I am making
