If a steam-pressure canner is deep enough, you can use it for a water bath. Cover, but do not fasten. Leave petcock wide open, so that steam escapes and pressure does not build up inside the canner.

Glass Jars
Be sure all jars and closures are perfect. Discard any with cracks, chips, dents, or rust; defects prevent airtight seals.
Select the size of closure—widemouth or regular—that fits your jars.
Wash glass jars in hot, soapy water and rinse well. Wash and rinse all lids and bands. Metal lids with sealing compound may need boiling or holding in boiling water for a few minutes—follow the manufacturer’s directions.
If you use rubber rings, have clean, new rings of the right size for the jars. Don’t test by stretching. Wash rings in hot, soapy water. Rinse well.
