This tutorial page
shows the basic procedure for casting objects in moulds, in this case we
are casting a transparent blue doorknob from the latex mould made in the

To ensure your mould doesn't fall over during the casting process,
secure your mould to a base, using Plasticene
Carefully pour out required amount of resin to completely fill the mould
(allow small amount extra, better to be too much than not enough).
Mix the pigment thoroughly into the resin (if you are filling the resin
with powders this is the stage to add them).
After carefully measuring the correct amount of catalyst (1 to 2%) stir
into resin completely, minimum workshop temperature 16ºC.
SLOWLY pour catalysed resin mixture into the mould (remember to do this
as slowly as possible to reduce the risk of introducing unwanted air
into the casting.
Allow casting to cure (approx 4 hours in normal room temperature 25º C).
Pure resin castings can be quite brittle so take care when affixing
them, using an epoxy adhesive or similar.
Resin part filled with mineral powder is opaque but can still be
pigmented and is tougher, with care it can be drilled and tapped if
Note: Achieving a glass clear surface using latex moulds can be quite
difficult, best results are achieved when the resin is filled with
mineral powders etc.
