Question: How can you tell if a glass bottle is vintage?

Check the bottom of the bottle for what is known as a pontil mark. This will be a ring or area of rough glass from where a supporting rod held the bottle during glass blowing and definitively dates the glass as being vintage.

What are the numbers on the bottom of glass bottles?

Many bottles have numbers on the base. These marks can be used to identify a mold in a glass factory. A number of the same molds would be serially numbered, such as 1 to 12.

How do you tell the difference between cut glass and pressed glass?

Cut glass will have sharper detail with a more defined pattern, whereas pressed glass will be smoother and worn to the touch. Look for mold marks. Cut glass will not have any mold marks and most pressed pieces do unless they are upper end pieces where someone took the time to remove them.
