Buying vintage is usually a green option, since it allows you to reuse items, but when it comes to dishes, there is a bit more work needed to make sure you don't end up using lead-based plates, cups and bowls. Ceramic tableware that is highly decorated or has decoration on top of the glaze could be loaded with lead. Generally, when in doubt, don't buy these items. But if antiques interest you, pressed glass is a safe way to go. And remember: Never use questionable vintage plates and bowls to serve food and drinks to children.
