To tell if pewter is lead free, test it using a simple yellow-orange precipitate made of tin or lead iodide. While this method is not definitive, it is fairly common. There are other methods of testing that are more accurate and do not require the use of expensive equipment. If you’re looking for an antique piece of pewter, a lead-free sample might be worth its weight in gold!

Test for lead in pewter

In 1974, lead was removed from pewter composition. In 1994, European directive BSEN611 reinforced this standard. Today, pewter is made from a mixture of tin and other metals. This makes it a predominantly tin-based alloy, and pewter traditionally contains copper and antimony. To test for lead, dip a pewter object in a solution of white vinegar. The yellow precipitate is a sign of lead acetate or lead carbonate.

The alloy made from pewter contains 92% Tin and 7.5% Antimony. Tin is refined from lead ore, but trace amounts are left in the casting alloy. While all pewter contains trace amounts of lead, the level of lead is lower than the Food and Drug Administration’s (FDA) standard of 500 parts per million. Pewter made to meet the standard is labeled as “lead free” pewter.

Pewter has traditionally been grouped into three grades. Fine pewter is used for eating ware, while trifle pewter is mostly for drinking utensils and is duller in appearance. Lay pewter is not for eating and contains up to fifteen percent lead. Testing for lead in pewter can help you ensure the safety of your pewter jewelry and other antiques. Just follow these steps to avoid getting yourself into trouble.

Care for lead-free pewter

To care for your pewter, you need to keep it clean. This is not an impossible task. You can wipe away most of the dust, stains, and dirt with a damp cloth. However, if the pewter develops a light tarnish, you may need to polish it. A pewter polish is available at a hardware store, or an auto parts store may carry one with fine grit.

There are several ways to clean your lead-free pewter, depending on its finish and composition. For example, if you bought a pewter vase, you should use a paste made of flour and salt to clean it. Using this paste will ensure that your pewter jewelry stays clean for years to come. Alternatively, you can use a proprietary metal polish, but this may damage the piece.

Lead-free pewter is safe for food use. It is safe for contact with food and water. There is no concern about exposure to lead while wearing jewelry made from lead-free pewter. The metalloid antimony does not pose a health risk, but its compounds are toxic. Polished pewter is not the best option for storing food for long periods. It also does not hold a high temperature, making it unsuitable for use as a cookware.

Identifying lead-free pewter

Lead-free pewter is a metal alloy composed of tin, copper, and antimony. Historically, pewter was an alloy of 85 percent tin and 95 percent copper. Lead is no longer used in human contact, but trace amounts of the metal are still present. Lead-free pewter is classified as such, but the term “lead-free” is often applied to products made from pewter that may come in contact with food and drinks.

You can test for lead by purchasing a lead-testing kit from a hardware store. These kits work by swabbing a piece of metal with chemicals. The result will reveal if it contains lead or not. Using Plumbtesmo 90602 test spots, the Canadian Conservation Institute recommends that you use a non-preferred brand. Note that certain metals, including silver, cadmium, and strontium, can interfere with the lead test.

Detecting lead in pewter requires a bit of research. The American Pewter Guild defines lead-free pewter as a product with 90% grade A tin. This is important because lead leaches from pewter when exposed to acids. Lead-free pewter is generally safe for eating utensils. Lead-free pewter is not suitable for cooking due to its low melting point.
