The Lion Head Door Knocker is sand-cast in solid bronze and finished with a patina process to create a rich antique finish. The oiled bronze finish is attained by successively dipping raw bronze castings into a patina solution and then buffing them to a satin finish. With the repetition of this process Michael creates the rich, dark multi-tone finish of his Oiled Bronze. Your Oiled Bronze Lion Head Door Knocker was designed by Michael Healy, an accomplished Rhode Island artisan known for his Unique Door Knockers. The Lion, a symbol of majesty and grace, has been used since ancient times as a sculptured guardian of hearth and home.
