It is not safe to reuse commercial canning jars for home canning. The glass in home canning jars is thicker than in commercial jars and they are created specifically to work with 2-piece lids. It is also not advisable to use very old canning jars.
Food in Jars is my go to website for canning recipes. I would recommend her Tomato jam recipe - I can't live without it now! Her corn salsa recipe is also especially good.
A jar lifter is used to remove jars from the canning vessel so to prevent you burning your hands.
You shouldn't use the older canning jars for several reasons. They may "explode" when the cool air hits the jar as you move it out of the hot water or at any time during the cooling down period. They may not seal well and the food could become contaminated or poisonous. The bottom could simply "fall off" in the water during the canning process, releasing the food within the jar out into the water. Also, the older jars were not made for pressure canning and may not withstand the pressure.
The dishwasher will clean canning jars. The water will reach 150 degrees or hotter. Use your options on the dishwasher if you want hotter water.
No. Use glass jars that have airtight seals and can be sterilized. Plastic won't ensure your home-made mayonnaise will remain safe.
If cleaned thouroghly a doctor could possibly use it as a little cup for urine samples
Any glass jar is safe to use for canning purposes. The jar should be submerged in boiling water to disinfect it prior to use. Use new rubber sealing rings always.
Any Ball (Atlas or Mason) canning jar that is not a screw top is a collectible. These are no longer produced for canning. They had glass dome tops that were held down by a wire lever, and sealed with a gum-rubber sealing ring. Some screw top canning jars may be collectible items if they are no longer manufactured, or were manufactured by a company no longer in business. I still use my Atlas jars.
The purpose of canning food, whether commercially or at home, is to preserve the food for later use.
It is best to always wash any food storage container before using. After washing the jar and lid, and letting them completely dry, place the lid on loosely and store. It will be clean and ready to use later.
Canning or home canning is preserving fruits and vegetables at home in jars with lids that seal to keep them fresh. Canning is used to preserve any foods. Based on the food either a pressure canner or water bath canner are used. A pressure canner is just that, a canner that preserves food under pressure. This is used for meats and low acid vegetables - green beans, corn. A water bath is used for tomatoes and fruits in a syrup - plums, peaches, pears, raspberies. STRICT guidelines MUST be followed to use the proper procedure for the proper food to avoid salmonella, botulism, etc. If in doubt, freeze it. Canning Food used to be called "Putting Up" food. The common method was to boil the food (usually fruit or vegetables) in "Mason Jars" using the cooking process to force the air out of the jar causing a vacuum. This allows the food to remain edible for a long period of time.
