Frequently Asked Questions

Care and Maintenance

Wolfard Lamps are made from the finest heat-resistant glass available, which makes them more durable than most glass products. Just remember that any object made of glass isn't indestructible, so treat your lamp with reasonable care. We suggest cleaning them with hot, soapy water. You can even put them in the dishwasher. For best results, place lamp upside down so the reservoir doesn't fill with soap and water. Please call or email us if you have further questions.

Wolfard Oil Lamp Operating Instructions For Your Classic Oil Lamp

By following these few tips, you'll be able to get maximum enjoyment from your lamp for years and years to come.

Filling: The Classic Wolfard Oil Lamp is intelligently designed to be filled through the tube connecting the reservoir to the chimney. Using our custom designed Wolfard Filler Spout (sold separately), simply attach the filler spout to your Wolfard Lamp Oil bottle, insert the flexible tip of the filler spout into the opening in the side of the lamp, and then fill the fuel reservoir 2/3rds full. Remove the spout and insert the wick and wick holder into the reservoir (see below for how to adjust wick). Other methods include using our flexible Wolfard Funnel to easily fill with more flexibility, or using a conventional funnel while filling through the wick hole on the inside reservoir.

Lighting: The easiest way to light your Wolfard Lamp is with a long-tip butane fireplace lighter or a long fireplace match. Avoid tilting the lamp during lighting, since this could cause fuel to spill.

Adjusting the Flame: When properly adjusted, your flame should be just about the size and intensity of a candle's. You can adjust the flame by raising or lowering the wick in its glass holder - but be sure to let the wick, wick holder and reservoir cool down before touching!
The top of the wick should be just below the lip of the glass wick holder. If any part of the wick, including threads or frays, protrudes from the top of the holder, your lamp may smoke. During initial use, or when refilling, watch the lamp for 15 minutes to make sure it doesn't smoke. If it does, blow out the flame, allow the lamp to cool, remove the wick holder from the lamp and pull the wick lower down into its holder.

Choosing Lamp Oil: We recommend Wolfard Lamp Oil because of its clean-burning and odorless qualities. Do not using kerosene or cheap lamp oils, since they tend to smoke and have strong odors. Do not use solvents or fuels with lower ignition points than kerosene – such as alcohol, gasoline, paint thinner, or acetone - these are unsafe!

Cleaning: Because it's made from the finest heat-resistant glass available, your Wolfard Lamp is rugged enough to be cleaned in the dishwasher. For best results, swirl soap and water in the reservoir before placing your lamp upside down in the dishwasher so the reservoir can drain. Just remember that any object made of glass isn't indestructible, so treat your lamp with reasonable care.

Burn Time

The following table tells you approximately how long your lamp should burn between refills. Since each Wolfard Lamp is handblown, burning times may vary slightly depending on the reservoir's size and the flame's height. Flame height is adjustable by raising or lowering the wick in the wick holder. Wait approximately 5 minutes for wick to cool down before adjust the height
