Jar
A jar is a rigid, cylindrical or slightly conical container, typically made of glass, ceramic, or plastic, with a wide mouth or opening that can be closed with a lid, screw cap, lug cap, cork stopper, roll-on cap, crimp-on cap, press-on cap, plastic shrink, heat sealed lidding film, an inner seal, a tamper-evident band, or other suitable means. The English word "jar" originates from the Arabic word jarra, which means an earthen pot or vessel.[1][2]
Background
Jars can be used to hold solids too large to be removed from, or liquids too viscous to be poured through a bottle's neck; these may be foods, cosmetics, medications, or chemicals.[3] Glass jars—among which the most popular is the mason jar—can be used for storing and preserving items as diverse as jam, pickled gherkin, other pickles, marmalade, sun-dried tomatoes, olives, jalapeño peppers, chutneys, pickled eggs, honey, and many others.[citation needed]
Types
- Bell jar – typically used in scientific laboratories to produce a vacuum; also used in Victorian times for display purposes
- Cookie jar – typically ceramic or glass, common in the United States, Canada, and United Kingdom
- Killing jar – used to kill captured insects
- Leyden jar – a historical electrical capacitor
- Specimen jar – an instrument used in anatomy to preserve specimens
- Apothecary jar – historically for storage of medicines; made of ceramics or more typically in modern centuries, clear glass. Typically cylindrical or with rotationally symmetric decorative curves, sometimes with a glass disc foot separated from the main body. Modern glass versions are also used for artistic display of the contents.
- Modern glass food storage jars come in a variety of shapes, all of which have a circular opening on top for screwing on a lid
- [4]
- Economy round or wide mouth jars – tall but rotund cylinder slightly rounded at the top and bottom, relatively wide with a wide mouth, commonly used for sauces like a mayonnaise
- Paragon jars – tall and narrow cylinder, commonly used for pickled foods like olives
- French square or Victorian jars – roughly a small cube
- Spice jars – small cylinder or rectangular cuboid
- Hexagon or hex jars – regular hexagonal prism
- Mason jars – moderately tall cylinder typically used in home canning, sealed with a metal lid
- Kilner jar – similar to a Mason jar but sealed with rubber
- Straight-sided jars – cylinders with no neck. Squat straight-sided jars are suitable for creams which can be scooped out.
- Ancient ceramic types include
- Amphora – large, but typically holding under 50 L
- Pithos – very large, typically the size of a person and holding hundreds of liters
- canopic jar
Utility
Jars are sterilised by putting them in a pressure cooker with boiling water or an oven for a number of minutes. Glass jars are considered microwavable.[5]
Some regions[where?] have a legally mandated deposit refundable upon return of the jar to its retailer, after which the jar is recycled according to the SPI recycling code for the material.[6]
