Ancient oil lamps come in many sizes and shapes and are made from different materials. Typical materials are terra cotta, bronze, silver, ceramics, etc. The styles and origins can include; Persian, Greek, Chinese, Judean, Roman, Byzantine, Islamic, etc. Many of the terra cotta oil lamps have a nozzle, pouring hole, and a handle. Typically, these ancient oil lamps are mounted from underneath with a metal or acrylic armature to properly support it safely. Most ancient oil lamps look nice on a slight angle down with the nozzle at the lower end. 10-31 Inc. has been custom mounting ancient oil lamps for over 30 years and makes a very nice stand for these pieces. This gives the lamp a nice smooth custom fit and (for metal armatures) you can paint the metal to match where it touches the oil lamp so it blends without distraction.
 

Another alternative for mounting ancient oil lamps is to do it yourself. Art Display Essentials has stock “spider mounts” that can be used for that very purpose. They come in a basic “X” shape. You can bend the arms up to cradle the ancient oil lamp from below, and then you cut off any excess metal that is unnecessary to hold the piece safely. This will give it a clean look. If you like you can paint the arms the same color as your ancient oil lamp to get a nice blended and non-distracting look. You can see these “spider mount” options here:

The larger ancient oil lamps, including the ones made of metal, may or may not work with the stock armatures depending on size, shape, and weight. However, a custom mount can be fabricated by 10-31 Inc.
