THE AMATEUR WAX MANUAL
- Heat resistant kitchen gloves
- Heat gun / Hair dryer
- Spoons / Sticks
- Brown glossy packaging tape
Heat up the amateur wax (capa) in a pot using an old oven set at 100°C. This will help it melt faster, since the melting
point is at 60°C. To melt small amounts you can also pour very hot water over the granuals. Once the capa is liquid
you can add pigments to give it a color. Food pigments also work and keep the mixture non-toxic.
Take a bucket with cold water and make your hands wet, this will keep the capa from sticking to your hands. Take a bit
of hot capa out of the pot and be careful to not burn your hands, it can be very hot. Place your hands in the cold water
with the capa and mould it until it becomes hard. This helps to understand the transition from liquid to solid and the
different temperatures in between. As it cools down it changes from transparent to opaque.
Using a spoon or stick you can also take some hot capa out of the pot and drip it on to anything, e.g. on metal capa
will cool down faster and release easily.
There are also types of glossy brown packaging tape to which capa doesn’t stick. The more rough and pourous the
surface, the better it will stick.
Pouring the hot capa into a mould is also an option as long as you can release it.
Using a heat gun allows you to reheat, melt, add and take away pieces. You can change the texture of the surface
from rough to slick or make drippings. Also use it to connect two hard pieces of capa by melting both of the connecting
When joining different materials together, surrounding the joint with capa will make the connection super strong. For
additional strength you can drill a hole through the material near the connection to give the capa a better hold.
There are different grades of capa available. 6400 is a good all-around grade for free pouring, moulding in a form,
moulding by hand, splashing, etc, with good structural properties.
