Glass Industry Affiliations

The HHH Tempering Resources team maintains membership with the following glass-industry organizations:



After celebrating 20 years of service to the glass manufacturing industry, HHH Tempering Resources completed a planned leadership transition in early 2015.

During the transition period, previous majority owners Leon and Rick Silverstein moved ownership to an employee group of glass industry veterans and outside investors. A group of principal employees that includes: Mike Synon, Terry Hessom and HHH founders, John Haws and Keith Hunt, formed the new leadership team. As part of this planned organizational evolution, the Silverstein’s stepped down.  The current HHH team expressed appreciation for Silversteins’ 20 years of leadership throughout the transition.

In 2019, Salem Distributing Company, Inc. acquired HHH Tempering Resources, Inc. which is now a wholly owned subsidiary of Salem. Mike Synon, HHH President/CEO, as well as the rest of the HHH technical and leadership teams, will stay intact.
