PITTSBURGH CLAY POT COMPANY 
The manufacture of glass melting pots is a process re- 
quiring 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 manu- 
facture, as well as to acquire the skill necessary to build 
pots which will withstand the high temperatures and ex-

facture of glass. 
The Pittsburgh Clay Pot Company was organized in 
1879, and therefore has had more than 40 years’ experience
