Regular gas stoves can be converted to propane.
I knew of someone who pressure canned on a camp stove, Coleman type.
We do our canning on an electric stove using the boiling water bath method. We use one of the big roaster cookers to prepare the food item.
Preheat the glass jars in the microwave for about 15 secs. Jars will be very hot. Then pour the food preparation into the jars, put the flat on and loosely screw on the ring. (Never pour hot food into a cold jar) Then place the filled jars into a large pot of boiling water, being careful to not completely cover the top of the jars with water. Make sure the jars are full to within one inch of the top. Half full jars will break in the boiling water bath.Depending on the recipe for the item you are canning, boil according to instructions. Remove the hot jars and place them to the side. When you hear the lids “pop” the jar is sealed.
