How do I date an antique decanter?

Examine the base for a pontil mark, which indicates hand-blown manufacture before the widespread adoption of automated moulding in the late nineteenth century. Silver collars and mounts often bear hallmarks and date letters that provide exact years of manufacture.

What is the difference between crystal and glass?

True crystal contains a high proportion of lead oxide, which increases the weight, refractive index, and acoustic resonance of the material. Standard glass lacks this lead content, resulting in a lighter vessel with less brilliance when exposed to light.

How were pair of decanters used historically?

Dining hosts placed matching vessels filled with port, sherry, or madeira on the table or within bottle coasters for guests to pass clockwise. Different shapes identified the contents, allowing servants and diners to distinguish between red wines, white wines, and spirits.

Are coloured glass decanters authentic?

Coloured glass vessels in shades such as Bristol blue, cranberry, and green genuine period production techniques from the Georgian and Victorian eras. Artisans added metallic oxides to the molten batch to achieve these rich hues before cutting through layers to reveal clear glass underneath.
