The soap mixture once made will have
to be poured into a mould or moulds depending on what you want.
They come in various materials and
sizes so have a think about the shape of the bar of soap you want to produce
i.e. round, square etc.
The most important thing to remember
is, once you have poured the mixture into the mould it will set and you will
have to take it out. If it is in a silicone type mould you will be able to turn
it out easily but if it is in a rigid mould like wood it will be impossible to
turn out unless you have lined it – think about lining a cake tin.
Types of moulds
Wooden – will have to be lined
Wooden with silicone liner
Silicone – no liner required
Cardboard box – will have to be lined
PVC piping cut into lengths. Cap off
one end with plastic or card. Stand in a bucket just in case the capped off end
doesn’t hold and pour in soap mixture. Once set, cut another piece of plastic
or heavy duty card slightly smaller than the end of the pipe. Push the soap
through – it is difficult and you might need another pair of hands to help.
Sometimes, popping the pipe into the freezer for a couple of hours and letting
a bit of moisture form eases the soap out.
