Bottle dating machine
By Michael Veach Photos by Justin Thompson There is a lot of interest in collecting old ‘dusty’ bottles of whiskey.
These bottles had a seam that ran up the neck of the bottle.
Unfortunately, this made the neck a weak point in the glass and the bottles with long necks tended to break easily.
In the 1890s a three piece mold was developed with the neck being the third piece.
The seam in the glass runs up to the shoulder of the bottle and disappears.
The first clue for dating these bottles is bottle itself.
