How do I identify opalescent glass?

Opalescent glass shows a milky translucence that catches light with distinct blue or amber tones, particularly on raised moulded surfaces. This effect results from chemical additives reacting during the cooling process. Examination under natural light reveals the characteristic depth and shimmer that distinguishes these decorative plates and bowls from standard pressed glassware.

How were silver mounts attached to glass dishes?
