One approach to helping beginner identify their old bottles involves show them the bases of old bottles.

From the standpoint of most collectors of antique bottles, the name and location of the company the bottle was made for, and the name of the product that was originally contained in the bottle (one or both of which may be embossed on the bottle) is often considered to be of more interest or importance than the glass factory where the bottle was actually manufactured.
However, this site is geared with more emphasis on the actual themselves.

To aid beginning collectors and those interested in bottles I have developed a number of bottle time lines.One of the most frequently asked questions about old bottles is, 'How old is this bottle?'
