Oil Lamp Core
An oil lamp core, also known as a wick, is a crucial component of an oil lamp, responsible for drawing oil upwards through capillary action and providing a combustible surface for the flame.
Material
Traditionally, oil lamp cores were made from natural fibers such as:
- Cotton: The most common material, prized for its absorbency and relatively clean burn.
- Linen: Used historically, offering good strength but potentially less consistent absorption than cotton.
- Hemp: Less frequently used, typically in coarser lamps.
- Paper: Historically used in some designs, often rolled or braided.
Modern cores may utilize synthetic materials like:
- Rayon: A cellulose fiber offering good wicking properties.
- Acrylic: Can provide durability and resistance to certain fuels.
- Fiberglass: Used in some specialized applications for its heat resistance.
Purpose
The primary purpose of the core is to:
- Fuel Delivery: Transport oil from the reservoir to the flame.
- Combustion Surface: Provide a surface area for the oil to vaporize and burn.
- Flame Control: The size and structure of the core influence the flame's size and stability.
Function
The core functions through capillary action. The porous material draws the liquid oil upwards against gravity. Once the oil reaches the upper portion of the core, heat from the flame vaporizes it. The vapor then mixes with oxygen and combusts, producing light and heat. The core continually replenishes the fuel supply to sustain the flame.
Usage Scenarios
Oil lamps, and therefore their cores, have been used in a wide range of scenarios throughout history:
- Illumination: Historically the primary source of indoor and outdoor lighting.
- Religious Ceremonies: Used in various religious traditions for symbolic purposes.
- Emergency Lighting: Reliable light source during power outages or in remote locations.
- Decorative Purposes: Modern oil lamps are often used for aesthetic appeal.
- Heating: Some specialized oil lamps are designed for localized heating.
Common Types
- Flat Wick: The most common type, a flat strip of absorbent material. Often adjustable for flame height.
- Braided Wick: Consists of multiple strands woven together, providing a larger surface area and potentially a brighter flame.
- Hollow Wick: A tubular wick, sometimes used in specialized lamps for improved fuel flow.
- Fiberglass Wick: Used in oil lamps designed for kerosene or other fuels that may degrade natural fibers.
- Self-Trimming Wick: Designed to burn at a consistent rate, reducing the need for manual trimming.
Based on the material, use, and application, “oil lamp core” refers to a component used as a wick in oil lamps for illumination.
Here are the relevant HS codes found within the provided reference material:
- 8310000000: This HS code covers sign plates, name plates, address plates and similar plates, numbers, letters and other symbols, and parts thereof, of base metal, excluding those of heading 9405. While not a direct match, an oil lamp core could be considered a part of a lighting fixture if it's integrated into a more complex lamp structure. The base tax rate is 0.0%, with an additional tariff of 25.0% and 30.0% after April 2, 2025, resulting in a total tax rate of 55.0%.
- 9405502000: This HS code covers luminaires and lighting fittings including searchlights and spotlights and parts thereof, not elsewhere specified or included; illuminated signs, illuminated nameplates and the like, having a permanently fixed light source, and parts thereof not elsewhere specified or included: Non-electrical luminaires and lighting fittings: Incandescent luminaires designed to be operated by propane or other gas, or by compressed air and kerosene or gasoline. If the oil lamp core is part of a non-electrical kerosene or gasoline-operated lamp, this HS code may be applicable. The base tax rate is 2.9%, with an additional tariff of 25.0% and 30.0% after April 2, 2025, resulting in a total tax rate of 57.9%.
- 8545902000: This HS code covers carbon electrodes, carbon brushes, lamp carbons, battery carbons and other articles of graphite or other carbon, with or without metal, of a kind used for electrical purposes: Other: Arc light carbons. If the oil lamp core is made of carbon, this HS code could be relevant. The base tax rate is 0.0%, with an additional tariff of 25.0% and 30.0% after April 2, 2025, resulting in a total tax rate of 55.0%.
- 8545904000: This HS code covers carbon electrodes, carbon brushes, lamp carbons, battery carbons and other articles of graphite or other carbon, with or without metal, of a kind used for electrical purposes: Other: Other. If the oil lamp core is made of carbon and doesn't fall under the "Arc light carbons" category, this HS code may be applicable. The base tax rate is 0.0%, with an additional tariff of 25.0% and 30.0% after April 2, 2025, resulting in a total tax rate of 55.0%.
Important Note: The classification of "oil lamp core" is dependent on its material composition and whether it is part of a larger lighting assembly. It is recommended to verify the specific material of the core and the overall lamp construction to determine the most accurate HS code.
