PREP: Line your 9 bar Baltic Birch Mold with plastic. Your soap won’t actually be touching the plastic so it doesn’t have to be perfect but we want it covered just in case. Place the border pieces in the mold to secure the plastic.
PLAN: I like to plan ahead when possible. Place the dividers into the mold and start adding your rocks into the separate cavities. Figure out what will fit and look best. Carefully take out the rocks and try to keep them in the same order so you can work quickly when it’s time to mold the rocks.
ONE: Put on your vinyl gloves and mix up enough Flexy Fast to cover the entire bottom of the 9 bar soap mold with at least an inch of thickness. I mixed a large grapefruit size of the white and a kumquat size of the pink. Mix well with your hands just like taffy until you have a bubble gum pink color.
TIP: If you have never used Flexy Fast, watch this episode of Soap Queen TV. It will break down the basics for you in a step by step video tutorial. And yes, you’ll be able to use the Flexy Fast mold over and over again.
TWO: It’s time to work fast. Spread out the Flexy Fast on the bottom of your mold making sure to get it the corners. Place the dividers right into the putty. Then quickly press your river rocks into the putty in each individual cavity. Let the putty sit for 30 minutes to set up.
THREE: Once the putty has hardened, release the river rocks from the putty. I found it easier to take out the dividers too, just put them back in when you’re done.
FOUR: To make the rocks, melt down three different containers of melt and pour soap base so you have three different colors for your soap. I didn’t fragrance the rocks, but you can if you want to.
Container one: 2 oz of Aloe Melt and Pour with Liquid Green and Liquid Black
Container two: 2 oz of Aloe Melt and Pour mixed with Liquid Blue and Liquid Black
Container three: 2 oz of Shea Melt and Pour mixed with Liquid Black
Then use droppers to fill up the rocky imprints in the Flexy Fast. Notice I did several colors per rock. If you’re doing layers, remember to spritz with rubbing alcohol so the layers adhere. Have fun with it and remember they don’t have to be perfect. They’re supposed to be rocks!
FIVE: While your rocks are cooling it’s time to get started on the base. I love how my color turned out. I melted 36 oz of Aloe Melt and Pour with 2 oz of Shea Melt and Pour. This gives a unique cloudy effect without being totally opaque. Then I added a couple of drops of diluted Brilliant Blue LabColor. Finally, add 1 ounce of Kentish Rain Fragrance Oil and mix well. Once the soap has cooled to 125 degrees, spritz the rocks with rubbing alcohol and pour the final layer.
SIX: To unmold the soap, gently turn the mold upside down. Lift the mold off of the soap and remove the plastic. Then carefully lift the Flexy Fast from the soap and pull the sides of the mold away from the soap. Then admit it…these soaps ROCK!

Oh definitely – it gets hard quick. That does make it a bit tricky to work with but we think it’s worth it =)
I love using the flexy fast molding putty. But I just learned that when they say 3-5 minute pot life, they mean it! I mixed up a bit more than my hands could handle; but I still love the putty.

I’m not finished read this yet, but it’s so fabulous ‘n I’ll back again when I was finished my job 😀
These are amazing! you are sooooo clever Anne-Marie!
These are really, really fabulous. So creative, and they are beautiful!
Oh man, these are the bestest, cutest ever – what a great idea, and to think I was considering getting a really, really expensive “gem” mould for my my crystal soaps – you have given me a really great idea. Have you heard about that reusable/ remeltable silicone stuff you can melt in your microwave, that turns it into liquid and then you can pour it ove the thing you want to mould?. You guys should look into that as well – I can see you coming up with endless possibilities with that. You are so clever Anne-Marie!
Oh My Gosh! This is an incredible project. I thought by the title it was going to be gem rocks (which I love also) but these are really fantastic. You did it again!

Definitely! It would be a shame if the rock mold wasn’t reusable – but it is! =)
I love using it. I can make molds on the fly whenever I want. It really adds to my versatility as a soap artist.
The mold itself took about 15-20 minutes to make but since I can use it over and over again, it didn’t seem like a huge time investment over the long term.
Aw thanks. We were pretty excited when the soap got unmolded …
The Flexy Fast is sooooo versatile. You’re going to find all kinds of things you can mold with it =)

Love it!! I tried it your way and then I tried it by making a few molds of a couple different twigs with my Flexy Fast putty. Added them to my “stones” and suddenly I have “Sticks & Stones” soap. How cute is that?!?
What a fabulous soap…for nature types, zen types, kids, you name it! I can see it packaged up with cute little sayings like “you rock my world” or “you are a rock star”. LOL!
woww! very nice… thank you.

This is the coolest idea ever. My boys would love to do this.
Very cool…I too wonder if the rock mold would be reuseable?
Wow! All I can say is……WOW!!!
