I’ve had a ton of interest in the liners and wanted to show you how to use them if you purchased them.
They fit both 3″ PVC pipes and 3″ mailing tubes up to about 10″ tall.
I’ve had several people ask me how much soap their molds will hold. Here is the formula to use to figure this out.
3.14 x r x r x h x .4
where,
r = radius (center of your mold to the outside)
h = height
So if you have a piece of PVC pipe that is 3″ wide by 9″ tall you would figure 3.14 x 1.5 x 1.5 x 9 x .4 = 25.434.
We’ll round down to 25. This number equals the amount of oils in your recipe.
So back to lining the molds! Simply insert the liner into the mold. You might have to stick your hand down the inside to push it all the way down to the bottom.
The mail tubes are easy. You simply fold over the extra part of the liner sticking out.
The PVC requires one more step. Since the PVC is much thicker than the mail tube you’ll have to cut two slits in order to fold the liner over.
Fold over the sides and tape down.
One you fill either tube with soap pull up on the sides of the plastic to smooth out the wrinkles that might have formed.
Wait 24 hours and unmold!
If you would like to order liners they are 25 for $11.00. Click here!

Been thinking about making a batch of soap in PVC, but wasn’t sure how to figure out the soap amount – THANK YOU for the formula!!
I love these liners! Made my first attempt at PVC soaping a breeze! Only wished I’d known about this method before I spent hundreds of dollars on wooden molds. 😉
I’m so glad you like them, Leslie!!! 🙂
You can also blow into the mold once you place the liner inside to help smoothe out the lines before you pour the soap. Thanks for posting this Amanda 🙂 shout out to my soap teacher (my class was taught at gl candle supply in 2009). Happy soaping!!
Moya! How are you! Thanks for stopping by! 🙂
