Stove Compatibility

Gas and electric coil stoves work with all models.

Glass-top stoves: The 910, 915, 921, and 925 are suitable for glass-top stoves. The 930 and 941 are too heavy and too wide for glass-top stoves.

Weight: Typical flat-top stove weight limits are 50-60 pounds. The weights listed are empty. Add 20–30 lbs for water and jars in the 910–925, and 40–50 lbs in the 930 and 941.

Burner Fit: The canner diameter may extend beyond your burner and transfer heat to nearby surfaces — ensure adequate clearance from countertops.

Height clearance: If you're buying a 925, 930, or 941, measure from your burner up to your range hood or microwave before ordering — taller canners can be a tight fit.

Frequently Asked Questions

The Black Onyx 21 Quart Pressure Canning Kit is perfect for families of 2-6 people and is our most popular size. It holds 18 Pint Jars or 7 quart jars, which is ideal for most home canning recipes. If you're canning for a larger family or doing big batches, consider the 930 or 941 Pressure Canning Kits.

Yes, the Black Onyx 21 Quart Pressure Canning Kit works on glass/ceramic cooktops.

Correct! All American Canners use a precision-machined metal-to-metal seal. There are NO rubber gaskets to wear out, replace, or fail. Simply lubricate the rim as instructed, and your canner will seal perfectly for decades. Many customers use 40+ year old canners.

A pressure canner is larger and maintains precise pressure levels needed for safely preserving low-acid foods like meat and vegetables. According to the USDA, it must hold at least 4 quart jars to qualify as a safe canner. This Model 921 holds 7 quarts. You CAN cook in a canner, but you CAN'T safely can in most pressure cookers.

With proper care, your All American canner should last multiple generations. We regularly hear from customers using canners from the 1940s, 50s, and 60s that still work perfectly. The cast aluminum construction doesn't wear out, and since there's no gasket, the seal never fails. This is truly a lifetime investment.

This kit includes the All American 921BK Black Onyx 21 Quart Pressure Canner, a six-piece canning tool kit, and the Ball Blue Book guide to home canning.

A bundled kit gives you the canner, essential jar-handling tools, and a trusted guide book together, saving time and simplifying setup for safe home canning.

Yes. The Ball Blue Book is a classic guide that covers home canning fundamentals, recipes, and step-by-step instructions for preserving.
