Historical Tidbit: Beer Bottles and Sea Glass, pt 3

According to Pure Sea Glass, red is one of the rarest colors to find, and it often comes from fifty year old broken beer bottles:

One of the most coveted colors of beer bottles and sea glass is a deep red shade formerly produced by Anchor Hocking for Schlitz called “Royal Ruby.” Bottles of Royal Ruby were made in the 1950s and again in 1963. The Anchor Hocking Glass Company made these now rare red bottles by oxidizing copper to a precisely controlled state within the glass batch.

If you run across one of these red bottles at a garage sale or antique market, it may be well worth collecting!
