How do I clean an old censer?

Dust the surface gently with a soft dry cloth to preserve the aged metal patination. Avoid abrasive polishes or chemical dips that strip away historic character. Keep the interior free of ash build-up using a soft brush. Moisture should be kept away from any inlaid hardstone components.

Were these vessels used for burning incense?

These pieces were cast to hold burning incense sticks or cones within scholar's studios and temples. The thick metal walls safely contained the heat generated during ritual use. Many retain traces of historic use inside the bowl. Others served primarily as decorative display items in period interiors.

What do the marks on the bottom mean?

Impressed marks often name specific dynastic periods, reigning emperors, or scholar's studios. Names like Xuande or Wu Bangzuo appear on the base as stamps of traditional style. Later workshops frequently added these marks to honour earlier master metalworkers. Reading the mark helps identify the likely period of manufacture.

Why are some censers so heavy?

The metal was poured thick to ensure durability and stability during ritual burning. Large ritual vessels and scholar's pieces contain substantial amounts of cast bronze or brass. This high metal weight prevents the vessel from tipping when fitted with heavy covers or stands. It also provides the solid feel expected of quality oriental metalwork.
