Firing the Piece

Importance of first firing

The first firing, also known as the bisque firing, is an essential step in the pottery-making process. This firing is crucial for hardening the clay and making it more durable before the glazing process. The bisque firing removes any remaining moisture from the clay and transforms it into a sturdy ceramic material. Here’s why the first firing is important:

Removing moisture: During the bisque firing, any residual moisture within the clay evaporates, preventing potential issues such as steam explosions during the subsequent glaze firing. Removing moisture from the clay also minimizes the risk of cracking, warping, or collapsing in the kiln.
Strengthening the clay: The process of firing chemically alters the clay particles, increasing their strength and making them less porous. This strengthens the overall structure of your pottery and prepares it for the next stages of glazing and firing.
Setting the shape: The bisque firing ensures that the clay retains its shape and form. Firing the piece allows the clay to harden and stabilize, reducing the risk of deformation during subsequent firings or handling.
Creating a porous surface: The bisque firing leaves the surface of the clay porous, which allows for better glaze absorption during the glaze firing. This porous surface enhances the adhesion and vibrancy of the glaze, resulting in a more visually appealing finished product.

The first firing is an important step that provides a solid foundation for the glazing and finishing stages of pottery making. Proper firing techniques and temperature control are essential to ensure the best possible outcome for your pottery piece.

Preparing pottery for kiln

Before placing your pottery in the kiln for firing, it is important to prepare it properly to ensure even heating and minimize potential issues during the firing process. Here’s how to prepare your pottery for the kiln:

Cleaning the pottery: Make sure your pottery is clean and free from any dust, dirt, or contaminants. Wipe the surface with a clean, slightly damp cloth or sponge to remove any loose debris. This will ensure a smooth firing and prevent any unwanted marks or imperfections on your finished piece.
Proper kiln loading: Arrange your pottery pieces in the kiln with care, leaving enough space between them for even heating and airflow. Avoid overcrowding, as this can lead to uneven firing and potential damage. Space the pottery pieces evenly to allow for uniform heat distribution.
Supporting large pieces: If you are firing larger pottery pieces, provide additional support to prevent sagging or collapsing during the firing process. Consider using wadding, kiln furniture, or ceramic posts to prop up the piece and maintain its shape. Make sure to follow proper kiln safety procedures when using supports.
Kiln shelves and stilts: Place your pottery pieces on kiln shelves or use stilts to elevate them, particularly if you are glazing the bottom of the piece. This prevents the piece from fusing to the kiln shelf or distorting its shape during the firing process.

By taking the time to properly prepare your pottery for the kiln, you ensure even heating, minimize potential damage, and maximize the chances of a successful firing.

Understanding the stages of firing process

The firing process consists of several stages, each with its own specific temperature range and purpose. Understanding these stages allows you to control the firing process and achieve the desired results for your pottery piece. Here are the key stages of the firing process:

Drying: This initial stage involves removing any remaining moisture from the clay. The temperatures during this stage are generally low, gradually increasing to allow the clay to dry slowly and evenly. Proper drying is essential to avoid cracking, warping, or steam explosions during subsequent stages.
Bisque firing: The bisque firing, also known as the first firing, involves slowly increasing the temperature to around 1800°F (982°C) to harden and strengthen the clay. This firing removes any remaining organic material and transforms the clay into a more durable ceramic material. The bisque firing sets the stage for the glazing process.
Glaze firing: The glaze firing is the final stage of the firing process. During this stage, the pottery is fired at a higher temperature to vitrify the glaze and fuse it to the clay. The temperature can vary depending on the type of glaze and the desired results. It is crucial to follow specific glaze firing instructions to ensure proper melting and adhesion of the glaze.

Each stage of the firing process requires careful temperature control and precise timing. Monitoring the temperature and ensuring proper heat distribution within the kiln are essential to achieve the desired firing results for your pottery piece.

Final Inspection and Display

Assessing the finished product

Once your pottery piece has been fired and cooled, it is time to assess the final product. This involves carefully inspecting the piece and evaluating its overall quality, aesthetics, and functionality. Here are some key aspects to consider when assessing your finished pottery:

Structural integrity: Examine the pottery for any cracks, breaks, or distortions. Check the joints and seams for any signs of weakness or separation. Assess whether the piece feels solid and stable, or if there are any areas that may require further reinforcement or repair.
Surface quality: Assess the surface of the pottery for uniformity, smoothness, and any signs of imperfections or blemishes. Examine the texture, glaze, or decorative elements for any irregularities, drips, or defects. Ensure that the surface reflects the desired aesthetic and matches your original design concept.
Functionality: For functional pottery pieces, test their functionality by using or handling them as intended. Evaluate whether they serve their purpose effectively and comfortably. Consider the ergonomics and usability of the piece and make any necessary adjustments or refinements accordingly.
Overall aesthetic: Step back and evaluate the pottery from a visual standpoint. Consider whether the size, shape, color, and texture align with your original design concept. Assess whether the piece evokes the desired emotions or responses and whether it reflects your intended artistic vision.

Taking the time to assess your finished pottery allows you to evaluate your progress and identify areas for improvement. Be objective and honest in your evaluation, as this will contribute to your growth as a potter and enhance the quality of your future creations.
