Testing Pouch Sealants
By John A. Tuttle

Hi All, While the 'aging process' of the project still continues,
I thought it interesting enough to report one thing I've noticed over
the past two months.  I did not expect that dry heat would have such
a negative effect on the pouches.  Regardless of the sealant that is on
the leather, the leather (for lack of a better term) 'shrinks'.

To a degree, this was somewhat expected because of the decrease in the
moisture content.  But what's even more interesting is that the sealants
that actually seal the leather better are the ones that have the greatest
amount of shrinkage.  The test pouch that wasn't sealed has the least
amount of shrinkage.

What this tells me is that the shrinkage might have more to do with the
sealant than it does the leather.  On the other side of the coin, it
doesn't seem that extreme cold has much of an effect on the leather (or
the sealant) at all.  But, I won't know that for certain until I run
the leakage tests after the aging process is finished.
