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 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.
