Back in June (some 140 days ago) I placed three antique bottles in an ultraviolet (UV) light chamber I fashioned from an extra trash bin in my garage. The idea was to turn the bottles purple.
Not just any old bottle will
turn purple. The bottles need to have
been manufactured somewhere between the 1880s and the 1920s. Clear bottles from that era were manufactured
with manganese dioxide in the glass. When exposed to UV light, the manganese
dioxide turns the glass purple.
Yesterday afternoon, I fished
the bottles from the light chamber to check progress. They have definitely blushed to a deeper shade
of purple. I captured a couple images
of the bottles and then placed them back in the chamber again. I am going let the bottles “roast” in the
light chamber for a while more.
