Kiln Wood
Kiln Wood refers to wood specifically prepared and intended for use as fuel in a kiln. The term encompasses various types of wood selected for their burning properties and suitability for achieving the desired temperature, atmosphere, and duration within the kiln chamber. The selection of kiln wood is crucial in various crafts and industries that utilize kilns, including pottery, ceramics, brickmaking, and some specialized food processing.
The characteristics of ideal kiln wood depend heavily on the specific application. Factors considered include:
-
Wood Type: Different species of wood possess varying densities and resin content, impacting their burning temperature and duration. Hardwoods like oak, maple, and ash are often favored for their slow, even burn and high heat output. Softwoods, such as pine, can be used but generally burn hotter and faster, requiring more frequent refueling and potentially affecting temperature control.
-
Moisture Content: Kiln wood must be properly seasoned (dried) to reduce its moisture content. Green (unseasoned) wood burns inefficiently, producing excessive smoke and lower temperatures, potentially damaging the kiln or affecting the quality of the fired product. Seasoned wood burns cleaner and hotter, allowing for more precise temperature regulation.
-
Size and Shape: The wood is typically cut and split into manageable sizes and shapes to facilitate easy loading and efficient burning within the kiln. Consistent sizing helps maintain a uniform burn throughout the firing process.
-
Availability and Cost: The availability and cost of specific wood types influence their practicality as kiln wood. Locally sourced and readily available wood species are often preferred for economic and logistical reasons.
The use of kiln wood is often a skilled craft, requiring knowledge of wood properties, kiln design, and the desired firing process. The correct selection and management of kiln wood are essential for achieving consistent and high-quality results in kiln-based industries.
