My wife and I have been canning for over 20 years and we re-use our lids each year. Occasionally a jar will not seal (about 1 or 2 per year), but we have never gotten sick from our home canning. However, one must be prudent when opening a jar so as not to bend the lid unduly.

To can hot chili, cook the chili until done. Boil jars to clean. While chili and jars are still hot, pour chili in jars. Clean off any spillage on the top of jar. Place seal with rubber on top of jars and let cool. Check the jars to make sure they sealed by poking the tops. If the seal moves, it is not sealed. Put jar rings on sealed jars.
THe seal on a mason jar is totally airtight. This seal keeps foods preserved inside the jars.
To seal jelly jars with paraffin wax, make sure the jelly is hot and pour it into the jars leaving some space at the top. Melt the paraffin wax, pour a thin layer on top of the jam in each jar, and allow it to cool and harden completely before storing the jars.
You can stack filled jars if you place them in the boxes that the jar were purchased in. The screw on rims should be removed first. Do not stack one jar directly on top of the other as the weight could cause the seal to leak and cause food spoilage. I personally only stack my jars two high to avoid too much weight causing seal damage.

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.

To fix a toilet seal, you will need to remove the toilet, replace the wax ring seal, and then re-install the toilet. Make sure to clean the area thoroughly before re-installing the toilet to ensure a proper seal.
To store celery in mason jars for optimal freshness and longevity, first cut the celery into smaller pieces that can fit in the jars. Fill the jars with water and place the celery pieces inside, making sure they are fully submerged. Seal the jars tightly and store them in the refrigerator. Change the water every few days to keep the celery fresh.
