It depends on the glaze. I know this will take some heat (grin -- pun
intended) but I would suggest you do use a pyrometer. We have found that 25 - 50
degrees can make a big difference in how the glaze turns out. Also we have found
that the "alligator" type glazes do better with shorter reduction rather than
longer. We've found that shredded office papers get markedly better results for
us than newspaper.
You can't be certain of what temp you're getting to unless you use a
pyrometer. In fact I would suggest you use two. They just replaced the probe on the
studio pyrometer, so we did a firing with that one and a known pyrometer. The
new probe reads 25 degrees higher.
