Just as you might guess, it is steel coated with a thin layer of tin. Steel is an alloy of iron and carbon that is strong and light, and used in a wide variety of applications. Coating steel with tin helps prevent corrosion and is an old method of making food canisters. The first tinplate can was produced in London in 1812.

With long term exposure to acidic ingredients, tin can corrode and leach into food, so tin cans and lids are often lined to prevent this. Mason jar lids made of tinplate are usually lined with plastisol or unlined. The unlined lids should not be used to store anything acidic.

Tinplate lids will often eventually rust, usually only in areas where the steel is exposed and not tin coated such as lids with holes or cutouts. To avoid rust, hand wash and dry thoroughly. Rust is iron oxide, which is not toxic at the levels that could be found on a Mason jar lid, so if you do get a little spot of rust just try to wipe it off.

Tinplate is 100% recyclable.

The products that are unique to Mason Jar Lifestyle are designed by us in Denver. Other products are sourced wholesale from various sources.

Most of our products are responsibly made from high quality materials like 100% food grade silicone, 304 stainless steel, and borosilicate glass in China.

We are a very small company. So for now, we cannot afford the minimum order quantities and higher prices associated with manufacturing in the US. We would love to eventually source our products from America, and as we sell higher quantities we will definitely keep looking for geographically closer sources for our products.

Stainless steel is one of the best materials for food contact.

It does not react with food and does not leech anything into the food. It is dishwasher, freezer, and oven safe.

Products made of stainless steel have a very long life. The fact that they can be reused almost indefinitely makes them very eco-friendly.

It is used widely in almost all aspects of food production, storage, and service.

Most of the products we sell are made of 304 18/8 (18% chromium and 8% nickel) stainless steel, which is the most common variety used for food service.

We think silicone rubber is the best material available to produce a variety of products.

It is dishwasher, microwave, oven, and freezer safe. It is non-stick and easy to clean. It is very durable and will last a long time.

The FDA says that silicone doesn’t react with food or release any hazardous compounds. Because it is so inert, it is used in medical implants.

It does not leech anything into your food. There is some evidence that it may release tiny amounts of siloxanes into high fat foods at temperatures above 300°, but none of our products would be used that way anyway.

Silicone is eco-friendly because it is highly reusable and it is made of abundant and easily sourced elements like silicon (sand), oxygen, hydrogen, and carbon.

Plastisol is the material that almost all Mason jar lids that are intended for canning are lined with. The 2 piece lids that come with new jars and most 1 piece lids for canning have a plastisol lining. When it is heated during the canning process it becomes partially liquid. The primary purpose is to produce a vacuum seal once the plastisol cools and re-solidifies, but it also helps the lid to resist corrosion from acidic ingredients. Plastisol is a PVC product that is food safe, and most manufacturers now use BPA free plastisol.
