mold set up for the “reversed” plate
You will find in depth instructions for the
perfect “Reverse Fusing” on Page 2 of
this tutorial.
As you can see, most of the
luminescent coating has fired off. On
some of the pieces I added a small
piece of clear to show you what would
happen if you covered it with clear.
Evidently one piece of glass can give
you many different design options.
Enjoy experimenting!
This is the mold set up
for the “Fire Site Up”
plate. The handles are
raised with two smaller
pieces of KLB 1/2” high,
6” long and 1.5” wide.
The curved side is now
towards the mold/shelf.

Wissmach Glass Tutorial
Luminescent Glass!
In today’s project I will demonstrate how Wissmach
Luminescent Glass™ behaves in different firing
situation. Our preferred method is the reversed fusing.
I have to admit, since we can full fuse and slump in one
firing when using Kaiser Lee Board™, the luminescent
coating stays on very reliably in this type of firing.
Here is the KL-board mold set up for the
“reversed” plate. I used a carved board and added
two building blocks to each side. The building
blocks are carved down on an angle which will
create the curved up “handle” for the plate.

The luminescent coating does not act like a release
(only irid and dichro coating do not stick to KLB)
therefore we recommend either shelf paper or kiln
wash powder. Since we are working with a relief, I
prefer Thinfire™ paper over Papyrus™ paper.
Release
Bullseye Thinfire Paper™
Cut a piece of Clear (COE 96) Glass the size
of the mold (18” x 9”) and a piece of Thinfire™
paper the same size as your clear glass. Now
cut several pieces of Wissmach Luminescent™
in the same COE (96). Place the paper on the
mold and then place your luminescent pieces,
luminescent side down, on to the paper.
When you are happy with your design place the
clear glass on top and fire your plate. I fused
my plate at 1425 °F (770°C).
Luminescent side down on to the paper and covered with clear!
This is a sample of the black
luminescent fired coated side
up with a little square of clear
in the center. In darker colors
the luminescent coating
seems to stay better. The
clear glass cover in the center
is a good sample on how the
luminescent vanishes when
covered with clear glass or
any other colored glass..

While reversed fusing will give
you the best sparkle for your
money, I also love to use the
lighter transparent colors. I fire
them luminescent side toward
the mold or shelf and it will
shimmer through to the top.
