Hard To Find Glass Block

Pittsburgh Corning Corporation manufactured Pittsburgh Corning Glass Block products since 1937 and was the only domestic manufacturer in North America.  The comprehensive variety of patterns, styles, and sizes they offered were designed to work together in any project as a total system.  The company first started with the DECORA® and ARGUS® being the first glass blocks to roll off the production line in the Port Alleghany plant.  In 1958, Pittsburgh Corning's first rectangular glass blocks were introduced along with color coatings becoming available for glass blocks.  By the late 1970s they indicated an intention to discontinue their glass block production, but reconsidered at the request of prominent architects.  The 1980s brought a resurgance of glass block use especially in residential applications.  Due to popular demand for glass block in homes, Pittsburgh Corning released the Hedron Glass Block.  The Hedron glass block allowed for glass block walls to come perpendicular to each other at a 90 degree angle.  This block became commonly used to created glass block shower walls or partition walls.  By the end of the 80s, Pittsburgh Corning had introduced its first EndBlock.
