This air adjustment is important for reduction firings. For 20 years, I have
fired 2 updrafts: an Alpine and an Olsen. I find those Alpine burner tips
have been important in focusing the flame. The air intake on those burners
controls the quality of the flame--that is, reduction. On the burners that
are under the Olsen is an air adjustment that screws up and down. Leaving
3/16" open the whole time is best for my kiln. This greatly affects the
atmosphere going into the kiln. I can only get copper reds when I am careful
to have this air adjustment just "so". Bonita in San Francisco
