Today I removed the fibreglass form the clay, tidied it up (with an oscillating saw - an excellent piece of kit) and poured some of the silicone into the mould. The workshop shut at a very inconvenient time, so I have to pour the rest of the silicone tomorrow, which is only a time issue.

Learnings:

• Vaseline is a far superior release agent in comparison to lacquer and mac-wax when used between fibreglass and clay.
• On cavity moulds keep the in-between clay to gauge the amount of silicon you'll need, as apparently they weigh a similar amount.
• Never start a pour when the workshop is about to close.
