I recently moved to Alpine Texas, elevation 4,600, and have had some
problems getting reds in cone 9-10 reduction firing. I understand that
the elevation may affect the atmosphere in the kiln, less oxygen in the
air, but will it be that significant. Any suggestions would be
appreciated. I am using an old Alpine updraft kiln with forced air
burners. Would appreciate comments, remarks or warnings from others in
equal elevation or higher.
Thanks

Doug,
You didn't say what else has changed with your move. Did you bring the kiln
with you? If not, were you using forced air before? How much of an elevation
change are we talking about? 4600ft isn't exactly nosebleed territory. Even
natural gas can change composition with a geographical move. Have you
switched gases? Did you change material suppliers? The water you mix glazes
with is now different also. What I'm trying to point out is the fact a lot of
things beside the elevation has changed for you. Give us some more info and
one of may be able to help....
