Amazon.com Review:
This heavy-duty pressure cooker's large capacity is probably best utilized for canning (though it would also be great for a number of cooking tasks). A pressure cooker is generally recommended when canning vegetables and nonacid fruit, since the high heat that can be generated will kill more bacteria than a regular hot water bath. Made from cast aluminum, with sturdy screws to seal the lid to the pot, this pressure cooker requires no rubber or plastic gaskets or rings. Its 21-1/2-quart capacity holds 19 pint jars or 7 quart jars. A three-setting pressure regulator valve is included, and the pressure gauge gives a clear reading. Made in Wisconsin, this is an American classic. --Julija Gelazis

Rating : - Seems to work well
I purchased this for canning glass jars of pasta sauce. It is heavy and thick, well constructed, and works as expected.
