A glass stopper is often called a "ground glass joint" (or "joint taper"), and a cork stopper is called simply a "cork". Stoppers used for wine bottles are referred to as "corks", even when made from another material. [citation needed] A common every-day example of a stopper is the cork of a wine bottle.
Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.
Glass is a relatively heavy packing material and wine bottles use quite thick glass, so the tare weight of a full wine bottle is a relatively high proportion of its gross weight. The average weight of an empty 750 mL wine bottle is 500 g (and can range from 300 to 900 g), which makes the glass 40% of the total weight of the full bottle. [27]
When an aluminum or plastic bottle cap has an integral band, it is usually connected by thin bridges. They can be molded along with the cap or slit afterwards. [1] When unscrewing the cap, the frangible ring breaks: the ring can separate from the cap, and two separate pieces remain, the sealing piece and the leftover ring; or the broken ring can form a "pigtail" still attached to the cap.
Common cap sizes include 33-430 (33mm), 38-430 (38mm), and GL 45 (45mm). Caps range in size from narrow mouthed to wide mouthed and often a glass or plastic funnel is needed to properly fill a reagent bottle from a larger or equal sized container's mouth. Reagent bottle caps are commonly said to be "autoclavable".

A Champagne sword. Wine bottle openers are required to open wine bottles that are stoppered with a cork.They are slowly being supplanted by the screwcap closure. There are many different inceptions of the wine bottle opener ranging from the simple corkscrew, the screwpull lever, to complicated carbon dioxide driven openers.
