Would this be a old jar

I got one just like it that has turned purple.

You could hang it out in direct sunlight until it turns purple.

Just curious if any of you know why it turns purple. What's in the composition of the glass to make it do that. Thanks.

If the jar has a gray tint, it will turn purple. Clear glass won't. You will wait years for it to turn in the sunlight. A quicker, overnight way is to use a ultra violet light. Don't look at the light, it will burn your eyes.

Don't do this. Artificially coloring any glass will only degrade any possible collector value or price.

How valuable is a plain ketchup bottle, or a common medicine bottle, or an un-embossed whiskey bottle. The bottles I color have no value at all.

Another thought. Telegraphs used Leyden Jars before we had dry cell batteries. Flat top and similar shoulder.

Circa 1910 food jar, machine-made.

I like what Charlie wrote about it... Maybe a wax sealer jar, but the glass doesnt quite have the right age to it. Probably machine made food jar

Back in the day - they used to use (circa WWI), most jars were greenish when made. The makers of jars used Manganese Dioxide to clarify the glass, and turn it clear. Worked great. Except, at some point, when thrown in the trash and sunlight hit it for a length of time, the Manganese dioxide turned purple. Thus, you have a purple jar. Manganese + sunlight = purple glass jars. Kinda neat, actually.

By the looks of it you have an old wax seal canning jar. I think I see I a pontil scar so it's pretty early 1840s-1860s very nice find. But the picture isn't very clear.
