Hi, I found this bottle with a B in a circle and and 8 on the bottom of the bottle. I think it may be a Brockway, but I need help with the year and what is was used for. Thanks.

B in a circle: Brockway Glass Company “B in a circle” mark on bottles: Brockway Glass Company, Brockway, Pennsylvania (1907-1988)

This mark was adopted by Brockway Glass Company in 1925 and used on tremendous numbers of bottles, up until circa 1988.

The “B in a circle” mark is usually seen on the base, and seems to have been placed in the center of the base on most earlier bottles (I don’t have a timeline to indicate HOW early), but by the late 1970s, if not earlier, the “B” was typically placed near the top, as in the 12:00 position on a clock (See pics below of late 1970s-early 1980s bottles). However, keep in mind that this typical placement of the mark is not 100% consistent, and some bottles made by Brockway might not conform to this general rule (Glass Bottle Marks 2017).

Related images, maybe yours? These do not seem to be an exact match but maybe the right type of bottle with incorrect matching dates to your bottle.

As for the use of the bottle - think Hot sauce or Tabasco
