 This
process can be a lot of fun and very rewarding.
I use algiform because it is an easy material to mix, it picks-up
great skin detail, and sets fast (about 5-8 minutes).
If you are making a face mold for the first time, make sure you
have a helping hand, that the model is comfortable and informed
of all the steps of the process. Gather all your materials and
do not begin applying the algiform until everyone and everything
is ready.
Once you start, make speed of application and the comfort of
the model the highest priority. The whole process should be done
in about 15-20 minutes.
Make sure the model has a clear breathing passage. Straws
wrapped in cotton can be carefully inserted in the nose. I usually
cut them in half so I don't hit them accidentally as I apply the
molding material. A tube between the lips can also be used for
breathing, but it will distort the mouth. If you are careful you
can work around the nose without blocking it.
Use warm water to mix the algiform (the paste will be more pleasant
for the model)
Use warm water for the plaster "mother mold" to accelerate
the setting time.
Do not trap any hair in the algiform or the plaster (use a thin
coat of vaseline for eyebrows). You do not need to add vaseline
to the eyelashes. If your mold is to cover the head, you should
cover the hair with a swim cap, and use a heavy coat of vaseline
on any hair that is going to be covered by the mold.
Algiform has a very short shelf life. It will dry out and become
very brittle within a day, so you should pour the cast
within a few hours of the completion of the mold. Wrapping
the Algiform in a wet towel and inside a ziploc bag will extend
its usefulness but not by much. |
