Brown / black bottle marked '6 TO THE GALLON' on base
We found a glass bottle under our house very old house while fixing the wooden floors. The earliest records we have of the house is 1858, but we are not sure how old it really is.
The bottle is brown (can be black as well) and it is marked with the words ' 6 TO THE GALLON ' on the base of the bottle. See two photos of the bottle attached
Can anyone help us figure out the age of this bottle, maybe even the origin / what it was used for?
Our house is in South Africa.
It would be so interesting to try and figure out where this bottle fits into the story of our house and help uncover some of the history.
