Harold Mc Master - Glasstech

Glasstech

In 1971, with partners Norman Nitschke and Frank Larimer, McMaster started another glass company, Glasstech, which he sold in 1987 for $100 million. Glasstech was not an overnight success; in fact, they filed for bankruptcy protection more than once. However, McMaster, was "recognized as the world's leading authority on tempering glass, that is, compressing glass to add tensile strength" and Glasstech essentially created the market for tempered glass, receiving not only the sticker price, but also a royalty on glass produced, for machines that produce 80% of the world’s automotive glass.
