Mason jars are thick-walled, wide-mouthed jars made of heat-tempered glass. They are able to withstand the heat and pressure associated with water bath and pressure canning. Ordinary glass jars can break under the strain and heat of canning, so if you are planning on using a pressure canner, make sure that you use Mason jars or an equivalent canning-style glass jar.
