TL;DR: To create porcelain figurines, start by kneading high-kiln porcelain clay until smooth, then sculpt your form using basic tools. Bisque fire your piece at cone 04, glaze it with translucent colors, and fire again at cone 6 or 10 for a durable, glossy finish.
Step-by-Step Instructions
Begin by gathering high-quality porcelain clay, which is known for its fine texture and white body. Knead the clay thoroughly to remove air bubbles and achieve a uniform consistency. This preparation step is crucial because porcelain is less forgiving than stoneware if trapped air causes cracks during firing.

Next, shape your figurine using hand-building techniques like coil and slab methods, or use a wheel if you have the skill. Porcelain is very sticky and pliable when wet, allowing for intricate details. Use modeling tools to refine facial features, clothing folds, or animal textures. Remember to work slowly, as porcelain dries faster than other clays. If you are making a hollow sculpture, ensure the walls are even in thickness to prevent uneven shrinking and cracking.
Once your sculpture is dry to the bone-dry stage, which feels light and chalky, it is ready for the first firing. Place it on a clean kiln shelf and bisque fire at cone 04. This low-temperature firing hardens the porous clay body, making it ready to absorb glaze. Avoid rushing this stage, as porous bisqueware absorbs glaze unevenly, leading to poor surface finishes.
After the bisque firing, allow the piece to cool completely before applying glaze. Dip, brush, or spray your chosen glazes onto the surface. Porcelain shines best with thin, transparent glazes that allow the white body to reflect light. You can layer different colors for artistic effect, but be mindful of how they interact. Ensure the glaze covers the entire surface evenly to avoid bare spots that may crack.
Finally, fire the glazed piece at the appropriate temperature for your glaze, typically between cone 6 and cone 10 for high-kiln porcelain. This high-temperature firing vitrifies the body, making it waterproof and extremely durable. Let the kiln cool slowly to prevent thermal shock. Your finished porcelain figurine will be smooth, strong, and beautiful, ready for display.
FAQ
Q: What is the best temperature for firing porcelain?
A: High-kiln porcelain is typically fired between cone 6 and cone 10, depending on the specific glaze and clay body used.
Q: Why does my porcelain crack during firing?
A: Cracking often occurs due to uneven drying, trapped air bubbles, or placing the piece too close to the kiln walls where heat is intense.
Q: Can I use regular ceramic glaze on porcelain?
A: No, you must use glazes specifically formulated for high-temperature porcelain to ensure proper melting and adhesion to the vitrified body.
