What is the statute of limitations on a thread?
Picking up on one from 9 years ago:
Has anyone had experience with calcium carbide
furnaces? I see on a thread from 1998 (see below)
that we may have an acetylene
gas furnace as mentioned below. We're working on a
late nineteenth-century site an came down on a layer
of crazy brick red dust with white wormy inclusions.
We heard from local informants that there may have
been a carbide furnace located on the site. If anyone
has had experience excavating one of these features
please let me know!
