A Weck jar is a glass jar used in home canning to preserve food. It has a rubber gasket with a glass lid.
A Weck jar is a glass jar used in home canning to preserve food. It has a rubber gasket with a glass lid.
The jars were invented and patented by Rudolph Rempel. Johann Carl Weck purchased the patent from Rempel, and in 1900 Weck and his best salesman George Van Eyck founded the J. WECK Company in Germany. In 1902, Weck left the company, Van Eyck continued to improve the design and function of the jar, and started exporting the jars outside of Germany. He trademarked the name WECK and his strawberry logo is still used today. [1]
The glass jars come in a variety of shapes and sizes, have rubber seals, glass lids, and stainless steel clips.
Food is processed in Weck jars using the water bath canning technique, not a pressure canner. During the canning process the lids are secured by the clips which must be removed once the processing is complete and the jars have cooled. A correctly sealed jar is indicated when the tab of the rubber seal points downward. New rubber seals should be used each time food is processed.
Pressure cooking is the process of cooking food with the use of high pressure steam and water or a water-based liquid, inside a sealed vessel called a pressure cooker; the high pressure limits boiling and creates higher temperatures not possible at lower pressures which allow food to be cooked much faster than at normal pressure.
Canning is a method of food preservation in which food is processed and sealed in an airtight container. Canning provides a shelf life that typically ranges from one to five years, although under specific circumstances, it can be much longer. A freeze-dried canned product, such as canned dried lentils, could last as long as 30 years in an edible state.
A drink can is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic drinks, fruit juices, teas, herbal teas, energy drinks, etc. Drink cans are made of aluminum or tin-plated steel. Worldwide production for all drink cans is approximately 370 billion cans per year.
A bottle cap or bottle top is a closure for the top opening of a bottle. A cap is sometimes colorfully decorated with the logo of the brand of contents. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass; plastic caps are commonly made from polyethylene or polypropylene, while metal caps are usually either steel or aluminum. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle.
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.
A blender is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances. A stationary blender consists of a blender container with a rotating metal or plastic blade at the bottom, powered by an electric motor that is in the base. Some powerful models can also crush ice and other frozen foods. The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container.
A stopper, bung, or cork is a cylindrical or conical closure used to seal a container, such as a bottle, tube, or barrel.
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish.
Tamper-evident describes a device or process that makes unauthorized access to the protected object easily detected. Seals, markings, or other techniques may be tamper indicating.
Apple butter is a highly concentrated form of apple sauce produced by long, slow cooking of apples with apple juice or water to a point where the sugar in the apples caramelizes, turning the apple butter a deep brown. The concentration of sugar gives apple butter a much longer shelf life as a preserve than apple sauce.
A Mason jar, also known as a canning jar, preserves jar or fruit jar, is a glass jar used in home canning to preserve food. It was named after American tinsmith John Landis Mason, who patented it in 1858. The jar's mouth has a screw thread on its outer perimeter to accept a metal ring or "band". The band, when screwed down, presses a separate stamped steel disc-shaped lid against the jar's rim.
Ball Corporation is an American company headquartered in Westminster, Colorado. It is best known for its early production of glass jars, lids, and related products used for home canning. Since its founding in Buffalo, New York, in 1880, when it was known as the Wooden Jacket Can Company, the Ball company has expanded and diversified into other business ventures, including aerospace technology. It eventually became the world's largest manufacturer of recyclable metal beverage and food containers.
Glass milk bottles are glass bottles used for milk. They are reusable and returnable – used mainly for doorstep delivery of fresh milk by milkmen. Once customers have finished the milk, empty bottles are expected to be rinsed and left on the doorstep for collection, or rinsed bottles may be returned to a participating retail store. Bottle sizes vary depending on region, but common sizes include pint, quart or litre.
A Kilner jar is a rubber-sealed, glass jar used for preserving (bottling) food. It was first produced in 1900 by John Kilner & Co., Yorkshire, England.
John Landis Mason was an American tinsmith and the patentee of the metal screw-on lid for antique fruit jars commonly known as Mason jars. Many such jars were printed with the line "Mason's Patent Nov 30th 1858". He also invented the first screw top salt shaker in 1858.
Ground glass joints are used in laboratories to quickly and easily fit leak-tight apparatus together from interchangeable commonly available parts. For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints may be rapidly fitted together to reflux a reaction mixture. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or rubber bungs and glass tubes as joints, which took time to prepare as well.
Home canning or bottling, also known colloquially as putting up or processing, is the process of preserving foods, in particular, fruits, vegetables, and meats, by packing them into glass jars and then heating the jars to create a vacuum seal and kill the organisms that would create spoilage.
The Fowler's Vacola jar is a molded glass jar used in canning for food preservation. It is the most popular home canning system in Australia.
A jar opener is a kitchen device which is used to open glass or plastic jars. A jar is sealed by either (a) a screw-off rubberised lid or (b) a lid placed on the opening of the jar with a rubber sealing-ring between. Screw-off lids are usually made of metal with a thin rubber sealing layer, whereas lift-off lids mostly consist of glass.
A flip-top, swing-top, lightning toggle, or Quillfeldt stopper is a type of bail closure frequently used for bottles containing carbonated beverages, such as beer or mineral water. The mouth of the bottle is sealed by a stopper, usually made of porcelain or plastic, fitted with a rubber gasket and held in place by a permanently attached wire bail. The bottle can be opened and resealed repeatedly without the use of a bottle opener, with the wires acting in the same way as a latch clamp. The flip-top was the dominant method of sealing beer and mineral water bottles prior to the invention of the crown cork.
