From 1870 to 1930, many unique shapes and colors were used to
distinguish poison bottles so they looked completely different than any
food or medicine bottle.
Bright colors like cobalt blue and emerald green were typically used.
They were often embossed with the words "POISON" or "NOT TO BE TAKEN".
A unique shape was needed so our ancestors would know what one feeled
like when groping around in the medicine cabinet during the dark middle
of the night.
Poisons were often had quilted patterns like diamonds or hobnails.
They often had vertical or horizontal ribbing.
Some had unique shapes like a skull or coffin, which are very rare.
Clear colors are also rare since most poisons were green or blue.
