Using a mould
Found objects: Items such as antique buttons make
great moulds. Be sure not to mould copyrighted items.
However, if a design is changed significantly then
it is not infringing copyright. We recommend not
using anything that has a copyright to avoid any
issue.
Original art
Your own original art is the most rewarding for
making moulds. You can create a prototype in polymer
clay. This allows you to work slowly and experiment
along the way. Alternatively you can make a mould
of a fired piece of PMC.
Two part mould compound
This two part mould compound remains flexible and
requires no release agent when used with PMC.
Making moulds
- Take an equal amount of the two different
coloured mould compounds.
- Rapidly and aggressively knead to two
together until they become a uniform colour.
- Roll the mixed compound into a ball and
then a cone shape.
- Place the compound onto a piece of paper
and push the object as far as is necessary.
Push the compound up around the edges of
the object. (Do not cover it completely
as you won’t be able to get it out.)
- Allow this to set for 15-60 minutes.
A finished mould will not dent when you
push it with your fingernail.
- To test if the mould is ready simply
try to gently peel the compound off the
object. If ready the mould compound will
come away easily without leaving a residue.
- When set remove your original and the
mould will be ready to use.
