PITTSBURGH CLAY POT COMPANY

The manufacture of glass melting pots is a process requiring
 the most painstaking care and minute attention
to details. Years of experience are required to properly
select, combine and prepare the clays used in their manufacture,
 as well as to acquire the skill necessary to build
pots which will withstand the high temperatures and extremely
 trying working conditions incident to the manufacture
 of glass.
The Pittsburgh Clay Pot Company was organized in
1879, and therefore has had more than 40 years’ experience
