"Is there anything special
I have to do to fire striker glass? Can I mix striker and non-striker in
the same kiln or piece?"
Strikers generally need a two-hour soak at slumping
temperatures, about 660C. This heat soak
helps ensure full development of the colour. If the soak is not long enough,
the colour may not achieve the target colour at all, or be paler than
anticipated.
The rate of advance to the heat soak is not critical. But it does need to be the appropriate rate
for the thickness and nature of the assembly of glass being fired.
If you were to have too short a heat soak, you can fire
again to help mature underdeveloped colours.
This will, of course, change the profile of the finished piece.
Strikers are compatible within their manufacturer’s own
range. So, they can be combined in the same piece as any other of the glass in
the fusing compatible range. That means
that they can be fired in the same kiln load as non strikers.
The two-hour soak at slumping temperature will not harm the later
stages of firing, but it might lead to use of a slightly lower temperature tack
fusing than without the long heat soak.
That is because of the heat work put into the glass at the lower
temperature. Only observation will tell
you how much less temperature is required.
It may be possible that only a little less time at the forming
temperature is required. Again, only
observation will tell you that.
Strikers require a heat soak to mature the final
colour. These striking glasses are
compatible with the rest of the fusing range from a single manufacturer. Glass
from different manufacturers must be tested for compatibility before combined
into a project.
Thanks for that, did not totally realize
