I just bought this 6-cavity mold to try my hand at making soap stones. Can anyone tell me how many ounces of oils it takes to fill it? I'm guessing it's about a 1-pounder, but not sure.
Soap stone mold quantity?

Find out how much water in ounces fills 1 of those cavities and then multiply that by 6 to find out the volume in ounces to fill all 6 of those cavities. Take that number and multiply by 1.8. Take that number and then multiply by .4. This will give you the weight in ounces for the amount of oils you would need in your recipe to fill that mold. If you are working in grams just take that final number and multiply by 28.35.
For instance if it takes 3oz of water to fill one of those cavities then you are taking 3 x 6 = 18
Then it would be 18 x 1.8 which is 32.4
Then it would be 32.4 x .4 which is 12.96
12.96oz of oils for your recipe to fill that mold or 367grams - Remember that this final number is by WEIGHT and not volume.
The above is just an example of the calculations. To get the correct answer you have to get that first number by filling one of the cavities with water.
Also, where did you get that mold?

Thanks, @SoapDaddy70 . I was being a bit lazy trying to avoid doing all that math
, but your numbers work for me, so you did it!I bought the mold on Amazon: Amazon.com: Emousport 6 Cavity Stone Shape Silicone Cake Mold Baking Moulds Pastry Decorating Molds Tools for Soap, Muffin, Brownie, Mousse: Home & Kitchen

I actually have that mold. I find that 23 total ounces (fats and liquids) fill it nicely. That translates to about a pound of oils, more or less, depending upon your fats used and water discount.

I wouldnt be surprised if most of the beautiful ones you are seeing were made with melt and pour. Individual molds are harder to get cold process soap batter to gel so you would most likely get a matte softer type of look rather than those super shiny pics you have in your original post.
An in the pot swirl would work nicely. I've also used this method, and the soaps turn out beautifully
That's a great video, @dibbles -- those are beautiful!
@SoapDaddy70 , I've watched quite a few videos, all of cold process soap stones. I like the matte finish. Makes a soap that looks like it's been washed in a moving river.
Lots of lovely variations. I'm eager to give this a go soon!

Agreed. Both with Dibbles and SoapDaddy. The gorgeous soap stones that look like quartz are M&P but as Dibbles' post shows, ITP makes gorgeous stones. That's generally what I do.
One word of warning--it doesn't matter what soap recipe or fragrance I use, the soap stones get TERRIBLE soda ash. So bad that I need to rinse them off to even see the swirls. Next time I use the molds, I'm going to spray them with
alcohol as soon as I unmold them.
The soaps that look like quartz are off the Amazon site so I didn't pay them any attention. The results from ITP videos are gorgeous and more of what I'll be aiming for.
Thanks, @Carly B for the warning about soda ash. One of the videos talked about that as well. She commented that the cavities she overfilled a bit had no ash because that made a better seal against the air. I'll try your suggestion about spraying with alcohol.
Getting ready for a market this weekend, so I'm hoping I can get to the stone project soon after that!

I was wondering something similar, those things are shiny! I suspected some marketing trickery personally. If its M&P, heck doesn't all M&P start off the same way as any other soap+PG, glycerin, etc? I'm sure we can do it without buying a base.
