These bottles, with the shorter neck and higher kicked-base, date from between c. After , bottles slowly became taller and thinner, resembling the more modern wine bottle by the middle of the 18th century.

A New Method for Dating Ancient Glass
One can find quite a bit of information on my web site and across the Internet about dating bottles based on whether the mold seam goes up and over the lip or if the bottle has a ‘pontil’ on the base. Even given these descriptions beginning often mistake a machine made Owen ring on the base of a bottle with a pontil. Specifics on what a pontil looks like or how to tell the age based on the mold seam can be found in Bottle Basics. While these two characteristics are often a strong clue to age, readers will be further helped by developing an understanding how the various categories of bottles changed over time.

Glass was highly valued across the Roman Empire, particularly a colorless, transparent version that resembled rock crystal. But the source of this coveted material — known as Alexandrian glass — has long remained a mystery. Now, by studying trace quantities of the element hafnium within the glass, researchers have shown that this prized commodity really did originate in ancient Egypt. It was during the time of the Roman Empire that drinks and food were served in glass vessels for the first time on a large scale, said Patrick Degryse, an archaeometrist at KU Leuven in Belgium, who was not involved in the new study.
Glass was also used in windows and mosaics. All that glass had to come from somewhere.

Dating antique bottles requires knowledge of the evolution of bottle technology and the ability to research manufacturers and bottling companies. Although glass bottles have been made for a few thousand years, it was not until the 19th century that bottle use became common, coinciding with the industrial revolution. By the midth century, embossed lettering and marking on bottle bodies and bases, denoting manufacturers and products, made more precise dating possible.

We had a great question last week on whether there were any efforts to date window glass. As you might know, there were two usual ways to produce window glass by hand which were used until the early s — crown glass and cylinder glass. In general, crown glass was used in older construction, with cylinder glass becoming more prominent during the Victorian era as larger windows with fewer individual panes became desirable.

Curator’s Corner. Between 0 and c. With the exception of returnable-refillable beer and soda bottles, most of this glass was not supposed to survive its single use. Possibly the company thought more of its products because every bottle was marked with a factory and date number on the bottom. Michael Owens learned glass making in Wheeling. He subsequently invented a series of bottle making machines which his company sold to other bottle makers, besides using them in their own factories.

Fission track dating is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium -bearing minerals and glasses. The method involves using the number of fission events produced from the spontaneous decay of uranium in common accessory minerals to date the time of rock cooling below closure temperature. Fission tracks are sensitive to heat, and therefore the technique is useful at unraveling the thermal evolution of rocks and minerals.
Most current research using fission tracks is aimed at: a understanding the evolution of mountain belts; b determining the source or provenance of sediments; c studying the thermal evolution of basins ; d determining the age of poorly dated strata ; and e dating and provenance determination of archeological artifacts. Unlike other isotopic dating methods, the ” daughter ” in fission track dating is an effect in the crystal rather than a daughter isotope.
Uranium undergoes spontaneous fission decay at a known rate, and it is the only isotope with a decay rate that is relevant to the significant production of natural fission tracks; other isotopes have fission decay rates too slow to be of consequence. The fragments emitted by this fission process leave trails of damage fossil tracks or ion tracks in the crystal structure of the mineral that contains the uranium. The process of track production is essentially the same by which swift heavy ions produce ion tracks.
Chemical etching of polished internal surfaces of these minerals reveals spontaneous fission tracks, and the track density can be determined. Because etched tracks are relatively large in the range 1 to 15 micrometres , counting can be done by optical microscopy , although other imaging techniques are used. The density of fossil tracks correlates with the cooling age of the sample and with uranium content, which needs to be determined independently.
