Canning can be performed on a glass smooth top cooking surface or traditional coil element cooktop.
When canning for long periods, alternate the use of surface cooking areas or elements between batches. This allows time for the most recently used areas to cool.
Center the canner on the largest cooking surface area or element. On electric cooktops, canners should not extend more than ½" (1.3 cm) beyond the surface cooking area or element.
Do not place canner on two surface cooking areas or elements at the same time.
On ceramic glass models, use only flat-bottomed canners to avoid damage to the cooktop and elements.
For more information, contact your local agricultural extension office, or refer to published home canning guides. Companies that manufacture home canning products can also offer assistance.
