Re: [ATM] Gugolz pitch [SEC=UNCLASSIFIED]

["Fisher Nick" <Nick.Fisher@dotars.gov.au>]

> Basically, there was a hollow made in the side of a small hill and
logs were stacked and tilted about 20 degrees. Beneath the lower end,
there was a bucket that would presumably collect the pitch that would
run down the length of the log. I think it took a pretty long time,
perhaps a few months or more.

The wood was actually heated by fire as well: when wood is heated in an
oxygen free environment the resin/pitch runs out and leaves behind
charcoal.
