Lost wax bronze sculptures that are numbered and signed at the base are generally considered limited edition, high-quality, or artist-proof (AP) castings. This method (also known as cire perdue) is an ancient, precise technique often used for creating detailed, valuable art, frequently featuring a signature and edition number (e.g., 5/100) on the bronze itself, often near the base.
Key features of these sculptures include:
Signature & Numbering: A signature, the edition number, and sometimes a foundry mark are usually engraved, cast, or signed by the artist directly on the base.
Method of Creation: Created using the lost-wax process, where a wax model is melted out of a mold and replaced by molten bronze, ensuring high accuracy and detail.
Limited Edition: These pieces are usually produced in limited runs, which increases their value and collectible status.
Patina: They are often finished with a specialized patina (chemical, heat-applied color) to enhance aesthetic appeal, such as brown, green, or gold tones.
Mounting: Small to medium sculptures in this style are frequently mounted on a marble or stone base, sometimes featuring an artist's nameplate.
Such pieces are often described as "hot cast" and are prized for their artistry and investment value in galleries and collections.
