Question: How can you tell how old a brown bottle is?

In a 3-piece mold, a seam often runs horizontally around the shoulder of the bottle with opposing seams on the neck. To some extent, the height of the mold seam on the bottle can indicate age. However, there are plenty of exceptions to any kind of “thermometer” rule (ie. the higher the seam goes, the newer the bottle.)

How do you date old brown glass bottles?

The seams on a bottle are indicators of how it was made and also indicate its age, says the Society for Historical Archaeology. If a vertical seam ends below the lip and the bottle has no horizontal seams, the bottle was most likely hand-blown into a mold.

Are old brown bottles worth anything?

The Age of the Bottle While not all old bottles are valuable, an older bottle is more likely to be worth more than a newer one. Seams and pontil marks are two of the ways you can determine a bottles age. The pontil mark is the mark at the bottom of the bottle where it was attached to the glass blowers pontil rod.
