- "James G. Pennycuick, vice-president and general superintendent
of the Prismatic Glass Company, of Toronto, Ont., has located in
Chicago with headquarters at 170 Lake Street, where samples of the
prismatic glass are being shown to the trade. The glass is smooth
on its outer surface, but has semi-prisms on its inner surface. A
cross-section would look like the teeth of a saw. The glass polarizes
the sun's rays and diffuses a white light, making it very servicable
for dark rooms and basements. It also destroys the glare of the sun.
One of Chicago's new skyscrapers is to be fitted up with the prismatic
glass." —Paint, Oil and Drug Review, Volume 22,
