How were bottle coasters used at the table?

Coasters circulated around the mahogany dining table after the servants withdrew, allowing guests to pass bottles of port and claret smoothly without scratching the polished wood surface. The raised sides kept the bottles secure as the stands slid from guest to guest during post-dinner conversation.

What is the difference between sterling silver and Old Sheffield plate?

Sterling silver consists of solid precious metal throughout, marked with hallmarks indicating purity and origin. Old Sheffield plate uses a thin sheet of silver fused onto a copper base. Old Sheffield plate pieces often reveal a warm copper tone along high points where the silver layer has worn down through generations of polishing.

Why do many coasters have wooden bases?

Turned wooden bases provided a sturdy, level platform to support heavy glass decanters and wine bottles. Mahogany was chosen for its durability and rich dark tone. Green baize or felt was typically glued to the underside of the wood to protect fine dining tables from friction.

How can I tell a George III coaster from a later piece?

Later pieces from the twentieth century often display simpler machine-rolled rims. Examining the construction methods underneath the wooden base helps distinguish period hand-assembly from later manufacturing techniques.
