Sitka EMC

[Richard Moody]

Sooner or later there may be demonstrable empirical difference
between artificial drying and natural drying of sound board
material.  I bet I  can sell more "natural seasoned" boards  than
"forced dried" boards.   Anybody hiring that has sb material over
seven years old? ---rm

Before going in oven the EMC was 8.5%. It required 7 hours in the
oven between 220 F and 250 F (much longer than I thought would be
required). As of an hour ago, the sample had been out of the oven
for 29 hours - it is in my shop at 72 F and 46% RH. The MC has
only risen to 2.45%.
