Striking Temperature

Postby franking1818 » Thu Dec 28, 2017 7:11 am

At what temperature do strikers change? Is it different for specific colors? Today I'm interested in lacy white, but I have others and will want to know at what temperature each strikes if they have individual striking temperatures.

Does lacy white remain translucent or does it become more opal?

Hi,

Lacy White 000143 was designed for stained glass application, and, outside of fusing compatibility, we don't grade it for fused color. It is a translucent white sheet with catspaw patterning. When it strikes, it can fire to a translucent while, or a fairly opaque white--our quality assurance team does not grade it down based on the striking color, just the compatibility.

Is there a particular temperature at which glass strikes (if it is a striker)?

Info from Bonnie:

Strikers develop color at different temperatures (and with different heatwork). Our video Heatwork & Color: Sheet Glass handles the basics about strikers with visuals for different categories including Cadmium-Seleniums, Golds & Whites. Page 2 of Catalog 11 also provides information including 3 styles fired from 1150-1480°F. In general, target color range for a given style, is achieved at a full fuse and color development is often evident at lower temperatures (1375-1450).

About Lacy White, we do have a sample that shows very little opalization when fired 400°F/hour to 1250 for :10. Much of the texture & catspaw patterning is intact. Full fuse is a somewhat uneven, translucent white.


The link to the video is here: http://www.bullseyeglass.com/education/ ... s-162.html

The link to Catalog 12, which includes the same article Bonnie mentions, is here: http://www.bullseyeglass.com/images/sto ... 2_full.pdf

Bottom line, is, we don't have a reference guide to every individual striker's temperature. Personally testing for your application and kiln is key.
