MOLD VOLUME
Figuring out you Volume for your mold.Pi (3.14) x Radius x Radius x Length x .4 = OZ. SO, in a 3" PVC mold the Radius is 1.5"If you use lbs. in Soap calc. Take your oz. and divide by 16. 16oz in a lb. So, let us say my mold is 13" tall. Here is the mathPI (3.14) x 1.5 x1.5 x 13 x.4 = 36.738oz. Want lbs. 36.738/16 = 2.296lbs. Round up or under.
GELLING YOUR MOLD
After you pour you need to gel. If you did not line your mold, gel, or water discount you will have to wait days to unmold.This is the key of getting the loaf out of the tube. If your mold will fit in your oven upright, use it. Put oven to 170, put plastic wrap over the top and shut off, Don’t over heat in oven, I like to use buckets with heating pads. I place my mold inside, turn on heating pad and cover with another bucket. I watch for gel and do not let it get to hot or you will get tunnels.
REMOVING FROM A PVC MOLD
Once cooled, you can place inside the if freezer it will not break loose. 1 hour. I drop the mold on a hard surface to break loose. If it is still stuck but moves some, I use soup can push inside MOLD to pop it out. If soap it is still frozen, wait for it to thaw before you cut.
