After talking about
mandrel we're going to talk
about
bead release.
Do you still remember, that there are different
materials use for mandrels? Depends on them,
there are also different ways to get the
mandrelout of the bead again. The cassava stalks would
be burned out during the fusing process in kiln.
Messing mandrels would be solved in acid
solutions. And stainless steel? So, now you
might already guess, why we need bead release.
It prevent the bead to stick on the
mandrelforever (well, most of the time at least ;)).
This one is stuck though - boohooo!!!
My own fault btw ;)You've got to know the characteristics of your
bead release. Depends on what kind of bead
you want to make, you might need another
bead release (some of them is sturdier than
the other) and make thicker or thinner
coating. Normally if you take the mandrel out
of the solution quickly, it will make a thicker
coating and vice versa. I speak from my own
experience ;) The stuck bead should be made
on a
mandrel with thicker, easy to loose coating,
but I didn't pay attention, as I was too excited
with my idea and wanted to try it right away.
My most used bead releases. As you can
see at the photo, it's a matter of point of
view, how you name it - do you want
to release the mandrel of the bead or
the bead of the mandrel? ;) The main ingredient of most bead releases is
kaolin, as it has to be resistant to the high
temperature of the flame. You dip the
mandrelinto the bead release, take it out and let it dry.
Another way is to flame-dry, but I don't like it,
since the coating is not as sturdy as the air-dried
ones. So, I always prepare them in forward and
only do the flame-dry, if I ran out of the
air-dried ones :)

Stay tuned! The next
B-word will come for
