Featured Glass bottle-18th century?

Hi all,got this cool antique dark olive green (almost brown) bottle for the equivalent of about $2. Image search suggests it’s possibly a porter or whiskey (or maybe beer bottle) What do you think? Any way to tell if it’s either 18th or 19th century? (Just for interest sake) It stands about 20cm tall. Thanks

 

reminds me of a Harvey's Sherry bottle..

 

This may help, lots of information ...

That link won't open for me so if anyone else is having trouble with it, here is another site to try.

I’m not good at dating bottles but I’d think late 19th or early ish 20th. This is a great site I found for identifying bottle lips. https://secure-sha.org/bottle/finishes.htm

 

hold it up to a good light source (sun, ceiling lamp etc) and let us know what the colour looks like

some of the early black (dark)glass bottles are just really thick coloured glass

if not seeing colour sideways, try straight on at the base or lip (at an angle)

 

It looks to be mid 19th c. Collected bottles years ago, had over 300.

 

Good site for information. Thank you

 

Thanks for the reply en link. Some interesting reading. Really several things to consider and look at when trying to determine age.

 

Appreciate the reply and help. Over 300,that’s good enough for me. That settles it then.. Thanks

 

Thanks for the tip. I did do this (just for interest sake) just looks like very thick olive green glass.
