LUTE (a packing ring of rubber for fruit jars)
LUTE
A common type of rubber seal for a jar is a gasket or O-ring. It helps create an airtight seal to keep the contents fresh and prevent leaks.
When the rubber sheet on a bell jar is pulled down, it creates a vacuum seal between the bell jar and the surface it is placed on. This vacuum seal allows for the removal of air from within the bell jar when connected to a vacuum pump, creating a vacuum environment inside the jar.
A Mason or canning jar.
Fog is a cloud that is formed when particulates in the air have attached to moisture thus making fog. You can make your own fog at home. Get a big glass jar, and a rubber seal that will fit over the opening. Fill the jar about half full with water, light a match and let it burn a bit inside the jar (just enough so you have a bit of smoke), seal the jar with your rubber seal. Now, you need to pump the seal for a bit and fog will form inside the jar.
I am fairly certain it is called the mouth.
THe seal on a mason jar is totally airtight. This seal keeps foods preserved inside the jars.
The jar has no particular name, but resembles an early type of mason jar, having a wide body and a narrower neck.
The jar is boiled so that it makes a tight seal in the jar.
Yes. Just put all the DRY ingredients into a mason jar and seal the mason jar. Open the jar, add water, and cook.
Cut up rubber drawer liner.
Scraping the inside of the jar with a rubber spatula is the most thorough way I've found so far.
