Still another Float Glass Question

[Valerie]

I did not do anything wrong...as such.
I dumpster dove a nice piece of 1/4" float.
Cut out 1/8" fiber paper pine trees ect.
spritzed on some borax and slumped.
500 dph to 1200 hold 20min
afap to 1450 hold 20 min then annealed
when I opened the kiln it was perfect..sorta
It was crystal clear!!! where is the beautiful pale green
I associate with fused float?? now I guess I will sandbalst
the front and slump for the matte finish Drat!
I want that pretty pale green color

it may not be standard float, but something else, like starfire.

The green color depends on the glass and mostly on the thickness. Most of the pieces I've done from 1/4 inch float only show color on the edges.

Thicker sections and edges will give you more color and another trick is to give the back a texture to help scatter light.

I recently fused some 1 inch square bars of float and they have a kilnwash finish on 3 sides. They glow GREEN in the right light. If sun shines on an end they really glow, about 10 inches ling.

Taking the glass out of flat usually accentuates the "greenness" It sounds like you got a colorless float like Starfire or Optiwhite...

I guess when you dive for stuff
you get what you get
1 more question...it is a rectagular shape
that I want to slump in a circular mold
less than 1/4" hangs over the edge on all 4 corners
if I ramp up then slump below 1200, will
the center drop enough so that the corners
don't grab over the edge?? gonna sandblast
and want the tm matte finish

it will almost probably be ok, but no guarantees. btw: failure could crush your mold if it's not steel. damhikt
