Crookes was appointed president

[Munnaf124578]

In 1913 Crookes created a 100% ultraviolet and 90% infrared blocking lens made from cerium-containing glass, but only lightly tinted. They were an unwanted by-product of Crookes's research to find a lens glass formulation that would protect glassworkers from cataracts. Crookes tested over 300 formulations, each numbered and labelled. Crookes Glass 246 was the recommended tint for glassmakers. The best-known Crookes tints are A (withdrawn because of its uranium content), A1, B and B2, which absorb all ultraviolet below 350 nm while darkening visual light. Crookes samples were made by Whitefriars, London, stained glass makers and Chance Brothers, Birmingham.Sweet Potato Pie is a Thanksgiving classic.
