MUHWA Ceramic Wick Holder for Alcohol Lamp — High-Temperature Replacement Wick Sleeve for Spirit Burners and Oil Lamps
MUHWA ceramic wick holder is a durable, heat-resistant replacement component for laboratory alcohol lamps, spirit burners, and oil lamps. Precision-formed from high-temperature refractory ceramic and kiln-fired for maximum strength and thermal stability, this holder replaces worn, cracked, or broken original holders to extend the service life of your existing lamps — no need to replace an entire lamp when only the wick holder has failed. The cylindrical design features an 8 mm outer diameter (fits standard 6 mm wick tubes) with an integrated top flange that sits flush against the lamp's wick tube opening, preventing the holder from slipping into the fuel reservoir. The central bore accommodates 6 mm cotton wick cord. Unlike plastic or low-grade metal holders, the ceramic construction will never melt, char, warp, or release fumes under continuous alcohol flame exposure. Compatible with most common glass, brass, and stainless steel laboratory alcohol lamps from major educational and scientific equipment manufacturers.
Key Features
- High-Temperature Refractory Ceramic — Kiln-fired at >1000°C for maximum thermal resistance. Withstands continuous direct flame exposure indefinitely without melting, softening, charring, or outgassing. Service temperature far exceeds any temperature reached by an alcohol lamp flame.
- Standard 8 mm OD / 6 mm Wick Compatibility — Outer diameter fits standard 6 mm internal-diameter wick tubes. Central bore accepts 6 mm cotton wick cord. Drop-in replacement for original ceramic holders.
- Integrated Top Flange — The flared upper rim sits securely on the lamp's wick tube opening, preventing the holder from being pushed or slipping down into the fuel reservoir. Provides a clean finished appearance and minimizes fuel evaporation.
- Chemically and Biologically Inert — Ceramic surface will not react with alcohol fuels (ethanol, methanol, isopropanol), leach contaminants, or support microbial growth. No corrosion risk — unlike metal holders that can rust or oxidize over time.
- Reusable and Long-Lasting — Infinite service life under normal laboratory use. Can be re-threaded with replacement wick cord dozens of times. Only physical impact (dropping from height) can damage it.

Installation Instructions
- Remove Old Holder — If the old ceramic holder is intact, grasp the top flange with pliers and gently pull upward. If broken, carefully extract fragments using needle-nose pliers.
- Clean Wick Tube — Inspect for debris or residue. Clean with a pipe cleaner moistened with ethanol if needed.
- Thread Wick Through — Cut a 15–25 cm length of 6 mm cotton wick cord. Thread through the ceramic holder's central bore from the flange side.
- Insert Assembly — Insert holder + wick into lamp's wick tube, ceramic end down, until flange rests flush on the tube opening.
- Fill, Saturate, Trim, Test — Fill reservoir with fuel, allow 2–3 minutes for wick saturation. Trim exposed wick to 5–8 mm. Ignite and verify stable flame.
Frequently Asked Questions
Q: Is this interchangeable with the ceramic holder in the 10-pack Wick Set?
A: Yes, this is the same ceramic holder design. The 10-pack Wick Set includes this holder pre-assembled with cotton wick. This listing is for the holder component only — ideal if you have your own wick cord and only need the holder.
Q: How do I know if this fits my lamp?
A: Measure your lamp's wick tube internal diameter. If approximately 6 mm, this holder (8 mm OD) will fit. The slight interference fit ensures a secure seal. For non-standard tube diameters, verify dimensions before ordering.
Q: Is the ceramic holder fragile?
A: It is robust under normal use and will not crack from flame heat. However, like all ceramics, it can chip or break if dropped onto a hard floor. Handle with reasonable care.
Q: How do I clean the holder?
A: Wipe carbon residue with ethanol-moistened paper towel. For stubborn deposits, soak in ethanol for 10–15 minutes, gently scrub with a nylon brush. Rinse and air-dry. Avoid abrasive cleaners or wire brushes.
