The Beauty of Frosted Glass

This chimney features frosting from the base to three-quarters of the way up, leaving the top quarter clear. This thoughtful design diffuses the harsh light from the flame or bulb, creating a soft, warm glow that's pleasant to look at and provides gentle ambient lighting. The frosted glass scatters light evenly throughout the room, eliminating harsh shadows and creating a cozy atmosphere perfect for reading, dining, or relaxing.

Perfect for Rayo & Central Draft Lamps

This chimney is precisely sized for Rayo and Central Draft burners, two of the most popular oil lamp burner styles. The 2 5/8" base diameter fits securely on the burner gallery, the 8 1/2" height provides optimal draft for clean burning, and the regular 3 5/8" bulge accommodates the flame without restricting airflow. If you have a Rayo or Central Draft lamp, this is the correct chimney size.

Ideal for Electrified Lamps Too

This frosted chimney isn't just for oil lamps—it's also an excellent choice for electrified lamps that have been converted from oil to electric. The frosting makes the light bulb less noticeable, maintaining the authentic oil lamp appearance while providing the convenience of electric lighting. The soft, diffused light is much more pleasant than a bare bulb, creating the warm ambiance of an oil lamp without the maintenance.

Superior Borosilicate Glass

Royal Craft lamp chimneys are crafted from borosilicate glass, the same heat-resistant glass used in laboratory equipment and premium cookware. This special glass resists thermal shock, meaning it won't crack when exposed to rapid temperature changes. The borosilicate construction makes these chimneys light, strong, and incredibly durable—they'll outlast ordinary glass chimneys by years.

Creates Warm, Inviting Ambiance

The frosted glass doesn't just diffuse light—it transforms it. Instead of harsh, direct light, you get a soft, warm glow that fills the room with gentle illumination. This makes frosted chimneys perfect for dining rooms, bedrooms, living rooms, or anywhere you want to create a cozy, inviting atmosphere. The diffused light is also easier on the eyes, making it ideal for reading or close work.

Versatile Oil Lamp Use

This chimney works with all types of non-electric lamps and lanterns that use Rayo or Central Draft burners. Use it on oil lamps, coal oil lamps, or kerosene lamps with flat wick burners. Whether you use your lamps for emergency lighting, off-grid living, ambiance, or historical authenticity, this frosted chimney delivers beautiful, functional lighting.
