Oval Tab Tutorial

base not shown |
Lay down your initial footprint approximately 1mm shy of the edges
of the cavity on both sides. You can check the size by either bringing
the mandrel down to the base of the
tool
for
reference,
or the
handle
portion of the tool up under your mandrel. It is better to estimate smaller
at first because you can always add more to the footprint. Once it's
on, you cannot take it off.

If you've followed our tip about determining
how
much glass you need for the cavity, you will know about how much
glass to wind onto your mandrel. The picture shows the suggested shape
before pressing.
It is almost round, but slightly tapered to the ends. If you have pointy
ends, that is not a problem, as long as they don't extend past the cavity
edges.
Do not press when soupy and fully molten. Wait until your glass starts
to slightly 'form a skin' (don't wait too long or you won't be able to
press). Allow your glass to begin to settle into the bottom of the tool so
it doesn't slide around too much when you begin to press. |

While centered over the cavity as
shown above, press straight down
while
steadying
the
tool against the back wall and left pole of the mold.
The pressing motion will take care of the pointy ends. You might notice
that the cooling of the glass from being in contact with the tools will
cause the surface to pull in slightly.

As you can see above, there are chill marks that show up more due
to the nice flat surface. It is well worth the little extra time it takes
to fire polish them away! If
you
like crisper
edges,
be sure
to
keep your flame on the faces of the bead, not the edges.
You can see that it does that neat bowing in that is due the the smooth
flat surface too. It gives them such a sensual feel! |
