Cabinet Hardware: Hand-blown knobs
The Old House Web
Trevor Braatz is the creator of these knobs for the small, family-run business. Knobs are produced from Borosilicate glass, better known as "Pyrex." In the past few years, Borosilicate glass has been produced in a variety of colors, and the material has gained favor with glass artists. Braatz says his knobs are stronger than other glass and have superior clarity and vivid colors.
