How much MP soap will my mold hold?

[Shelbyw]

My question is how do I determine how much Melt & Pour soap will my mold hold.

My thanks for any help!

If it is a mold that does not leak you can fill it with water and weigh. With m&p it is really no great big deal if you over estimate, after-all you can melt the excess down and use again
