Glass Canning Jar with Metal Lid - Illustration for Preserving Guides #3670079 (License: Personal Use)

This black-and-white line illustration depicts a traditional wide-mouth glass canning jar fitted with a two-piece metal lid system: a flat disc with a sealing compound and a threaded screw band. A paper or foil sealing strip is shown wrapped around the lid assembly, indicating an airtight seal used in water-bath or pressure canning. The clean, technical style suggests it’s intended for instructional or educational use rather than commercial packaging.

This image is typically used in DIY food preservation guides, USDA extension publications, canning manuals, or blog posts explaining safe home canning procedures. It serves users seeking visual clarity on jar components before attempting preservation, matching intent for safety, education, and step-by-step instruction.
