Finding the Right Recipe: Borosilicate Glass  Finding the Right
Recipe: Borosilicate Glass  Otto Schott, the pioneering German
glass chemist, made a glass that could reliably do something
that didn’t seem possible: endure sudden, uneven temperature
shifts without shattering. The key, Schott discovered in 1882,
was to have a critical amount of the element boron in the glass
recipe. Schott’s new durable, heat-resistant borosilicate glass
was an immediate commercial success.  Building on Schott’s work,
Corning chemist W. C. Taylor found the right recipe to make an
even more temperature-tolerant borosilicate glass. With it,
railway signal lanterns didn’t shatter in sleet or freezing
rain. By 1915, Taylor and chemist Eugene Sullivan had
transformed borosilicate glass into an exotic new product--
Pyrex® glass cookware. It captured America’s imagination. Soon,
in kitchens all over the country, people were cooking in glass.
Schott’s and Corning’s work launched the era of modern glass
chemistry research. Today, there
