Rainbow Hearts Melt & Pour on Soap Queen TV

Filed Under: Melt & Pour Soap

RainbowFinalwithMold_700px
This Rainbow Heart Melt and Pour soap will make you smile with plenty of sparkle, color and hearts. Inspired by a previous Soap Queen tutorial of the same name, the design has been updated to include more hearts and color in each bar. Pink Grapefruit Fragrance Oil gives the project a bright and happy scent.

This melt and pour soap includes six vibrantly colored heart embeds created with the Mini Heart Silicone Column Mold. Color blocks are used to give each heart a different rainbow hue. To help the layers and embeds adhere, having a bottle of 99% isopropyl alcohol nearby is crucial. Spraying rubbing alcohol in between and after pouring layers helps the soap stick together, and disperses any bubbles on top.

  1. Hello, I have a general question, not specific to this listing if you don’t mind. I’ve recently become addicted to soap making and have taught myself everything just from your site- I think I own close to all the items you have for sale now lol. My question is, I’ve noticed a “sweating” or s fuzzy layer come off my soap after using Micas to color- is there a trick? Am I using too much? Are there certain bases that work better with mica? I look forward to hearing Back, thanks! XoXo

    • Hi Wendy!

      Sounds like your bases are sweating, or forming glycerin dew. Melt and pour bases have additional glycerin added during the manufacturing process. That helps draw moisture to the skin, but also draws moisture to the bars. This is especially the case in humid climates. To prevent it, we recommend wrapping the soap tightly with plastic wrap and using a heat gun to shrink it on tightly. It also helps to store the bars in a cool, dry place. 🙂

  2. Hi. I’d like to make this soap but I don’t have the 10′ mold Anne Marie suggest in the video. However, I do have a 12′ loaf from you guys. How would i tweak the recipe to achieve the same results?

    • Hi Eboney!

      Both the 10″ Silicone Loaf Mold and the 12″ Tall Silicone Loaf Mold hold about 50 ounces, so you won’t need to adjust the recipe amounts! However, you may not be able to fit all three heart embeds in one layer. Because the mold is more narrow, you may want to do just two hearts per layer, or stack the third one on top. You can also do more layers with fewer embeds. So, you can do three layers with two embeds each. I would recommend testing the embeds in the mold before pouring any soap. That way you can see how to arrange them so they fit best. 🙂

    • Thanks Rebecca! This soap does feel really great on the skin. Have fun giving it a try. 🙂

  4. Hi can I use the Shea melt and pour for this instead of the ordinary white melt and pour?
    Many Thanks

  5. I’ve made this one twice! The first time turned out great, the second time I deviated a little to make it a little different, but I ended up liking the original the best! I decided to use the Coconut Mango fragrance and it smells amazing, I am tempted to try it again with Juicy Couture, I’m not sure yet. I really love some of these intricate loaf molds, I want to try the geometric mold next (my package with Kelly Green Mica and Yuzu Cybilla Fragrance just arrived today). Thank you all for the wonderful ideas, tips and tricks!

  6. I made this soap last weekend, and it most definitely requires patience if you don’t have six of the heart molds. My actual loaf ran into some problems though, and maybe you can help me trouble shoot. 🙂 My layers stuck together beautifully but what I did run into were little air pockets where the heart embeds met the white MP base. So, around some of the hearts there were little unsightly holes. I’m thinking maybe the white base cooled too much when I poured? The bars are still cute and usable, but I was striving for perfection! 🙂 Also, as a reminder, it may be important to mention that the heart embeds should not be placed directly up against the sides of the loaf mold…that is, leave a little space between the side of the mold and the embeds. Or, alternatively, once you’ve poured, gently pull the sides of the loaf to allow the white soap base to settle in around the embeds, so you don’t have an embed sticking out the side of your soap loaf.
    Overall, this recipe is clearly super adorable, but it is just slightly tricky. I appreciated the challenge. :))

    • Hi Nicole!

      You’re right, it’s definitely a more advanced recipe…and it requires some patience :). I think your hunch is correct; it sounds like your base was a little too cool when poured, which caused it to be a thick consistency. When the base is thick, air bubbles cannot rise to the top. I would recommend increasing the temperature by a very small amount and see if that helps. And you make a great point! Having a little space between the embeds and the side of the mold is important :).

  7. I’ve made this recipe twice and it has turned out adorable both times. The first time however it broke apart between all the layers. My second time I used a lot more 99% rubbing alcohol (can you use too much?) and let the layers harden for longer and poured at a couple degrees warmer and this seemed to help. My second batch I actually made 2 loaves for Valentines for my daughter’s class and the clear portion with the hearts came off of about 3-4 bars. I am curious if there is any other advice you can give me to help improve my 3rd batch?

    • Hi Amanda!

      I’m sorry those layers separated on you! There are a couple tricks that can help them adhere nicely.

      We recommend spritzing with 99% isopropyl alcohol right before the second layer is poured. If the alcohol is spritzed too early, it can evaporate. You want your layer covered with alcohol, but not completely soaked. Learn more about working with layers in this video: https://www.youtube.com/watch?v=5oyh1Bf3Gxo

      Read more about 99% isopropyl alcohol here: http://www.soapqueen.com/bramble-berry-news/sunday-night-spotlight-99-isopropyl-alcohol/

      Another way to help the layers stick is a nice sharp knife. I’ve found my layers separated on me when I used a dull knife, even with alcohol. I like using a sharp kitchen knife with a smooth blade.

      For the soap now, you can “glue” those layers back together with melt and pour! To do so, melt 1-2 ounces of clear soap on 5 second bursts. When it’s melted, brush a light layer on and gently press the separated soap on top. Let that harden for 1-2 hours. That should help your soap stick together. 🙂

  8. Hi,

    I am trying to purchase the Rainbow Hearts Melt and Pour Kit on Brambleberry but the Pink Grapefruit Fragrance Oil and Isopropyl Alcohol can’t be shipped to my country. In regards to the Alcohol, I can find it here but the Fragrance Oil is hard to find. Do you have any suggestions where I can get it from?

    I found this from another site but I don’t know if it will do.

    Thanks

  10. Thank you so much for the tutorial. I made this project yesterday with my round mold as I don’t have the heart yet and the top clear layer separated. It’s the second time this has happened even though I spritzed. Judging by the previous comments I guess I am not spritzing enough. I put mine in the fridge to cool. Would that make any difference?

    • Hi Dianne!

      You’re welcome, so glad you like the tutorial! When you put your soap in the refrigerator, it can cause the layers to dry at different rates. That can cause them to separate. We recommend letting that soap dry at room temperature so those layers stay together. 🙂

  11. Hello,

    I just made this soap and it looks lovely. So pretty! I was wondering if you can help me with layering. Maybe I spray too little alcohol but I have noticed when embedding and layering that in spots you can see the separation. I have poured at the stated temperature so the only thing I can think of is that I need more alcohol but I am not sure. Any tips in this area would be appreciated.

    Thank you,
    Debra

  12. Can I use Goat milk melt and pour instead of the white base? This so pretty, I love the hearts they look like glass.

  13. Do you have any tips for making just one layer of the melt and pour hearts and using them to decorate the top of a loaf of CP soap? I am wondering hiw well they would stay in place.

    Thanks so much for all your great recipes and soaping inspiration!

    • Hi Laurel!

      We love the way two layers look, but this soap would look awesome with just one layer! To help those embeds stick, I would recommend pouring a layer of white soap in the bottom of the mold. Then, let that harden. Spritz your hearts with alcohol and pour the second layer on top. Because the heart embeds are cut to fit in tightly, they should stay in place.

      Because you will have fewer hearts in the soap, you will need more white soap. It may help to make quite a bit so you have enough to fill the mold. Then, you can put the hearts and clear layer on top. 🙂

      -Kelsey with Bramble Berry

  14. I was kind of shocked that A-M didn’t spray the first layer before pouring the second layer. She only sprayed the hearts. I thought the layers would split if it wasn’t sprayed first. Did you guys have any problems with the soap you made in that regard?
