Title: Poplar Stains
Post by: dustineverett242 on March 30, 2012, 09:56:09 AM

Does anyone have any tips on drying poplar? Surface mold seems to be continuing to form during the drying process in the kilns. Is there a season that affects the forming of surface mold? Thank you.

What temperature are you running it up to??

how's your airflow??  Poplar readily gives up it's moisture and loves lots of air  :)  We see more stain/mold in the hot, sticky summer, but we'll see that stain before it ever reaches the kiln.  I would be looking at air velocity with uniformity being the key.  You sure don't want any dead spots in the kiln.

#1 could be low or inconsistent airflow #2 depression is too low not allowing the charge to vent enough  #3 if there is mold only in some of the packs (do you have moisture being re-introduced into the kiln due to a steam leak
