for assigning date ranges) especially on marks of pre-1900 bottles. In the great majority of cases, bottles with only numbers on the base are difficult, if not impossible, to attribute to a specific glass maker.For the most part, I have not attempted to list fine distinctions for marks that are found both with and without periods.

These variations in punctuation were common and probably reflected the whim of the mold engraver, thus having little or no importance (i.e. Some numbers served as date codes, or as some other type of internal code used by the factory.Online dating is now widely accepted as a valid, convenient & fun way of meeting like-minded people.New Zealanders using have found meeting people online is more convenient and comfortable than through 'normal' offline channels such as bars and parties.On earlier flasks, fruit jars, and soda bottles, and especially examples produced in the mid-nineteenth century period (1840s-1860s), the full factory name or initials may be embossed across the front.This list primarily includes marks that represent the actual glass company that made the container.THOUSANDS of bottles carry only a number on the base (or heel), and this information (in most cases) does not help ID the source or age………….nearly all glass factories used mold numbers on their containers at one time or another.
