How do I clean the interior?

Use a soft, dry cloth to dust the glass shelves and wooden surfaces without applying modern chemical sprays. Care must be taken around delicate inlaid banding and original mirror plates. Opening the doors periodically allows the interior to air out safely. Avoid placing damp or unsealed objects directly onto the wood.

Can these hold heavy china?

Most cabinets are built to support standard porcelain collections on their original wooden or glass shelves. Overloading individual tiers should be avoided to protect the internal supports. Heavier service sets are better distributed across the lower wooden base sections. Checking the shelf supports ensures stability for heavier ceramic pieces.

Are the keys usually original?

Many surviving cabinets retain their working brass locks and matching keys, though replacements are common in antique furniture. Original keys often feature simple barrel designs specific to the maker. Locks should be turned gently without applying excessive force to the mechanism. A professional locksmith can supply appropriate period-style replacements if required.
