Is it safe to drink from an old pewter tankard?
As a sommelier and brewer, I am frequently asked about the safety of drinking from old pewter tankards. While modern pewter is free from lead and completely safe to consume from, it is important to exercise caution when dealing with antique pewter items, as they may contain traces of lead.
Lead is a toxic metal that can have harmful effects on our health if ingested. In the past, pewter was traditionally made with a combination of tin and lead, which gave it a distinct greyish-black patina. This patina is a clear indicator that the pewter contains lead, as modern pewter does not develop this coloration.
To determine if an old pewter tankard contains lead, it is advisable to inspect its surface. Pewter items containing lead will often have a noticeable greyish-black patina, which can be seen as a tarnish or discoloration on the surface. This patina develops over time as the lead in the pewter reacts with air and moisture.
If you come across an old pewter tankard with a greyish-black patina, it is best to err on the side of caution and assume that it may contain lead. In such cases, it is advisable to refrain from using the tankard for drinking or eating purposes to avoid any potential health risks.
It is worth noting that the presence of lead in old pewter tankards does not automatically mean that they are dangerous. The risk of lead leaching into your drink or food is typically low, especially if the tankard is not used regularly or for acidic beverages. However, it is always better to be safe than sorry when it comes to potential lead exposure.
If you are unsure about the lead content in an old pewter tankard, it is recommended to consult with an expert or professional who specializes in antique pewter. They can provide further guidance on the safety of using the tankard and may even be able to test it for lead content.
While modern pewter is safe for consumption, old pewter items, especially those with a greyish-black patina, may contain traces of lead. To ensure your safety, it is best to avoid using these antique pewter tankards for drinking or eating. If you have any doubts or concerns, seek advice from an expert in antique pewter.
