Yep, I¹ll fess up to learning about Advancer shelves through trial and
Came in one morning to find the shelves stacked against the wall dripping
with condensation.
Called Smith-Sharpe, talked with Donna (those who have met her in the past
know all about that experience), she said wipe them off and fire away.
I did as instructed, no problem!
Best dry spot to store these shelves is inside the kiln!
