“See this rust?” asked a county-fair judge of a young 4-Her, pointing at a little spot inside the band the judge had just removed from the child’s jam jar. “This can keep your lid from sealing.”
I’d never known even the rustiest band to keep a mason jar lid from sealing, and I was startled to learn that a fair judge might withhold a blue ribbon because of a tiny spot of rust on the inside of a band. But I do think that rusty bands are ugly. If you want to make a good impression when you display or sell or give away your preserves, you’ve got to use brand-new bands.
But why must the bands go rusty by the second or third use? After one of my readers and I recently shared our annoyance at this, he started googling. To our mutual delight, he discovered a source for stainless-steel mason jar bands.
Maggie and Ryan Helseth, owners of Mason Jar Lifestyle, say that their rings are stain-resistant, not stain-proof; they may start to rust if they’re left soaking in water for days. But they won’t rust with normal use, including passes through at dishwasher. I’ve tested some of the stainless bands by using them in a boiling-water bath and by immersing them in water for a full day. So far they show no sign of rust.
As you might expect, the stainless-steel bands cost more than regular ones: You get five narrow-mouth stainless bands for $11.99 or five wide-mouth bands for $13.99. Because of their higher cost, and because the stainless-steel bands are identical in appearance and weight to regular bands, you’ll want to take care to keep the two types separate, so you don’t give away the good bands accidentally. If you do mix up your bands, though, you can tell the stainless from the soon-to-be-stained with the help of a magnet. The stainless bands, unlike the others, are not magnetic.
Maggie and Ryan sent me some of their other products to try. I am much taken with their silicone lid liners and sealing rings. Made of material that is stable and nonreactive—that won’t leach chemicals and won’t be damaged in a dishwasher—the liners can be used under plastic mason-jar caps or two-piece lids to keep food from touching metal or plastic and to keep plastic caps from leaking, a problem especially during transport to potlucks and picnics. Though flexible, the liners are sturdy enough, at 2.2 millimeters thick, that you can use them with rings alone. The sealing rings, like the lid liners, can be used with plastic Ball caps to prevent leakage and to provide an airtight seal—not for canning, of course, but for storage of unpasteurized foods in the refrigerator, freezer, or pantry. Ten silicone lid liners cost $13.99 in narrow-mouth size and $14.99 in wide-mouth. Ten silicone sealing rings cost $6.99 in narrow-mouth size and $8.99 in wide-mouth.
Maggie and Ryan also sell stainless-steel mason-jar caps, which come with their own removable silicone sealing rings (since the rings are removable they are also replaceable, although I don’t imagine they wear out fast). Without logos or other decoration, these lids are plainly attractive, especially if you dislike plastic. Like plastic mason-jar caps, the metal ones are not intended for canning. Five stainless caps with silicone sealing rings cost $16.99 for in narrow-mouth size, $18.99 in wide-mouth.
Self-described “mason jar geeks,” Maggie and Ryan have other products, too, such as a stainless lid with a hole for inserting a drinking straw. See all their stuff at masonjarlifestyle.com.
Update: August 24, 2016
A few of Maggie and Ryan’s customers have complained that the stainless-steel bands have come off in during processing, usually in a pressure canner, Ryan tells me. Because stainless steel is harder than tin, the threads on the Mason Jar Lifestyle bands are less well defined than those on ordinary mason-jar bands. Ryan is working with the factory to fix this problem. If you plan to use the stainless-steel bands for canning, I suggest waiting at least a few weeks before ordering them.
