Back to Basics® went back to the drawing board and designed a superior water bath canner. Improvements include a deeper pot allowing over an inch of water to cover the jars, a non-stick surface for easy cleaning, and a canning rack that keeps jars separated and safely off the bottom. Included with this large enameled water bath canner is a lid and a wire rack to hold 7 quart jars. The canner itself can also be used as a blanching or stew pot. The Back to Basics® water bath canner is coated enamel on heavy gauge steel. The canner does not have a flat a bottom, and for that reason the manufacturer does not recommend it for glass or ceramic top ranges, though reports have been that it does work fine on "most" flat top stoves.
