How to Make a Mason Jar Mold

260,710 Views
Ever wish you had a way to make a mold of your favorite things? Say... a mason jar? I've combined 3 ingredient to make these one of a kind mold you can use for anything! Here's how to make them:
Please note - do NOT use this DIY to make molds used for food or items you will ingest.
Time: 3 Hours Cost: $25 Difficulty: Easy
First, combine water and dish soap. I used a 1:10 ratio, favoring dish soap.
Next, squeeze a tube of 100% silicone caulk into the bowl. I had to get every ounce of this out of the tube to be able to have enough for my mold.
Then mix together the silicone until it becomes less sticky. This took about 5 minutes. Be sure to wear a glove as this is NOT chemical free. If you choose to not use a glove, you may experience a chemical reaction on your skin.
Once your silicone is less sticky, grab a smaller container (that you are willing to part with) and transfer the silicone over. Be sure to get most of the water off before transferring it.
Grab your positive (the object you'd like to make your mold out of) and place it into the silicone, pushing down to get it stuck. Let this dry in a safe spot for a few hours until totally dry and solid.
When the mold is hardened, pull the positive from the mold. It may be suctioned so be careful not to pull to hard. Now, you're ready to start using it!
First. I decided to make wax melts. You can find a tutorial here on how to make them: https://www.hometalk.com/27372627/essential-oil-melts
They came out so cute and such a good gift!
I also made cute hand soaps!
And an amazing tie-dye crayon! The possibilities are seriously endless. Once the mold is made, you can use it over and over again. Not to mention, these are PERFECT for stocking stuffers.

    This is interesting. Saw one that uses silicone caulk and baking soda. Will have to experiment with both recipes.

      Also have heard of using silicone and corn starch for molding and diy cellphone cases.

      I'm making $80 an hour working from home. I was shocked when my neighbour told me she was averaging $120 but I see how it works now. I feel so much freedom now that I'm my own boss. This is what I do... http://www.Jobzon3.com

    In answer to the question, the picture show a small amount of water, then a large amount of soap, then all of the silicone caulk. Right? This idea would be great to use to make candles, but don't forget the fragrance should be included when you add the wick!!....then put two of the molds together!! Wow!! Cute gift!!

    Unfortunate she doesn't give us the ratios although if I understand what I watched the water and soap are a 1 to 10 ratio at a just wing it amount. Kind of cool though that with a bit of playing around I can make a mold of any glass object and make soaps for gifts with the grand kids.

      She is talking about the silicone. A reaction to the silicone, if you don't use gloves, when you are mixing it with the soap and water. Not what you put in the mold.
