Method for calculating the volume of silicone required.
Before smearing the the box with Petrolium Jelly (Vaseline)
Mock up the mould box.
Then place some rice or dried beans or anything sililar but clean in the box spreading it out evenly at the level you require it, which should be minimum 10mm above the plug.
Then place this in a measuring beaker/jug.
If it comes to 100ml add 45% and this will be the volume of silicone required by weight.
N.B. Water has an SG of 1 and Mould Max 60 has an SG of 1.45
