I,m about to mix up some FWFL and reading through the different posts on the subject,my question is, the size block of beeswax is thought to be about 7 or 8 oz.Now is that by weight or melted volume.I have a block of wax that measures 2 3/4 x 5 1/4 x 1" and weighs 5 oz.I,m thinking that the amount of beeswax is approx the same considering the slight dimension difference,but why the weight difference. I did not check it's melted volume.I will be ordering some bee wax from randyrat very soon so I may wait to use his wax.Mine is fresh from a hobby bee keeper.I don't know if that would make a difference through
