This unfortunately limits the utility of the closure adding much refinement to the dating of a bottle that these closures are found on.

There have been many kinds of closures for bottles, ever since glass and pottery have been used for container materials.

Though thousands of closure designs were patented, and many hundreds used, just a handful achieved widespread popularity based on inherent simplicity and effectiveness.

The major closure types are what is covered on this page.

Thus, the incentive to develop varying closures was limited as cork sufficed for virtually all of the bottled products of the time.

Some of those newly discovered had their closures intact.Others, like the Lightning closure, was invented in the 1870s and is still in use today.Closures can also often assist in determining what type of bottle one has, i.e., what the bottle was most likely used for if (e.g., liquor, soda) it is not otherwise obvious.With that said we move on to the closures most commonly found on bottles made during the era covered by this website - the 19th through mid 20th centuries.The first is the ubiquitous cork closure, the use of which was at least partially pioneered by Dom Perignon.
