Are these pieces waterproof?

Most antique vessels function best as decorative objects rather than containers for water and fresh stems. Historic bodies and old glazes can be porous or vulnerable to moisture. If you wish to display botanicals, place a small glass container safely inside the neck to protect the interior.

Can I convert a vase?

Many examples on the market show past adaptations into table lamps, often with drilled bases or fitted hardware. Collectors weigh the presence of alterations against the decorative utility of the piece. Undamaged porcelain and bronze retain higher collectible standing when they preserve their original unaltered form.

How do I date these objects?

Examine the material, base characteristics, and enamel styles to establish a period of origin. Nineteenth-century production shows specific palette choices and manufacturing marks typical of the Qing era. Comparing potting weight, bronze patination, and glaze consistency against documented examples helps confirm the timeframe.
