Two-piece vacuum lids are made to release pressure by venting air from the jar after processing and upon cooling. When the lid does not vent, pressure build-up warps the lids. There are several possible reasons for lids to buckle when in a hot water bath or pressure canner:
- If the screw bands are applied too tightly it causes buckling immediately after processing.
- It you boil the lids (should be heated but not boiled) it softens the sealing compound too much, and results in a premature seal.
- Food spoilage due to incorrect processing produces gases inside the jar that force the lid to buckle or unseal.
To prevent buckled lids: Process foods using up-to-date guidelines, prepare lids according to manufacturer's instructions, and apply bands just until a point of resistance is met - fingertip tight.

What is a boiling water canner?
Typically called a "water bath canner" it consists of a large cauldron style pan with a removable rack to hold canning jars. Once sterilized canning jars are filled with food items and brand new jar lids are placed on each (with reusable rings finger tightened around the top of them) they are placed in the rack and lowered into boiling water. Most items call for 20 minutes of boiling - directions are given with canning jars - and a specialized jar remover tool can be used to take them out one at a time and set aside to cool. As the filled jars cool the lids will vacuum seal to the top of the jars forming a slight indentation on the top and a "pop" sound. The food is now preserved for storage without refrigeration. The appropriate food for this type of canning is jellies, jams, pickles and NOT meat containing items which are "pressure canned".

Leave recommended space between the top of the jar and rim.Add salt to canned vegetables, use 1/2 or 1 teaspoon. 5. Wipe jar rims with the cloth for a perfect seal. 6. After jars are completely cooled for 24 hours, press center of the lid. If a dip in the lid holds, then it is sealed. If lids pop up and down.then it's not sealed properly. 7.Store jars in a cool (50 to 70 degrees F), dry, dark place. Use within one year.
How can you can green beans?
Like other veggies, canning beans requires a pressure canner. Other acidic fruits, salsa and jams can be canned with a hot water bath canner. Pressure Canners will have directions in them for canning beans, depending on the type of bean you are canning. (When I was young, my mother used to can green beans in a hot water canner. We would put fresh green beans in jars with water, put the lids on loosely, place in the canner containing the same temperature water and heat to boiling, Boil for several minutes, then remove the jars and tighten the lids. As the jars cooled, the water and hot air inside would shrink, causing a vacuum which made the jar lids pop down and seal tight. We then put the jars in a cool dark storage area and ate them all year until the next harvest. Any jar that failed to seal became that nights supper. Boiling the jars and the water inside them killed any bacteria that could cause the beans to spoil, as well as anything that could cause disease. This method has been in use for hundreds of years and more information is readily available on the net.)

How do you can tomato juice without using a pressure cooker?
Twenty minutes in a boiling water canner usually does it. Use new lids on your jars and if the lids haven't popped after twenty minutes reboil them or use it right away. Most canners take eight jars. If you wipe the rims carefully before boiling and use new rings and lids they should all pop. Throw out any chipped or damaged jars each year.

How did people can vegetables in the early 1940s?
Canning in the early 1940's is not so different from home canning today. Glass canning jars are used along with a two piece lid. One part of the lid fits the mouth of the jar and is designed to seal under high heat. The second part to the lid is a ring that screws onto the jar to hold the seal in place until it has sealed. Jars and lids are sterilized before use. In the 1940's they would have been put into a pot of boiling water for several minutes. You can do the same now or use the dishwasher. The food is prepared to be canned. Most vegetables are cleaned and blanched, which means immersing them briefly in boiling water, then an ice bath. Fruits, meat and fish can go in as is. The jars are packed tightly so as not to waste space and then water is added to fill the jar. You can also add sugar to fruit. The lids are put on and the jars are immersed in a pot of boiling water. The length of time they remain is dependent on what you are canning. You can also use a pressure cooker for this step. Once the jars are done, they are removed with tongs and placed on a kitchen towel to rest undisturbed. Within the next several hours, you should hear the cans pop, which means they have sealed. Any jars that have not sealed within several hours can be re-done using a new seal or put into the refrigerator to be consumed within the next few days.
