Porcelain Vase Tutorial: Step-by-Step Guide to Creating Stunning Pieces
TL;DR: Craft a stunning porcelain vase by centering a ball of high-quality kaolin clay on a wheel and pulling up smooth, uniform walls. Finish your piece with a glossy glaze and a precise kiln firing schedule to achieve a translucent, glass-like durability.
Creating a porcelain vase is an art form that demands patience, precision, and an understanding of delicate materials. Unlike stoneware, porcelain is highly plastic but prone to cracking if mishandled. This guide walks you through the essential steps to transform raw clay into a breathtaking centerpiece.

Preparation and Centering
Begin by wedging your porcelain clay thoroughly to remove air bubbles, which can cause explosions during firing. Place a generous amount of clay on the center of your potter’s wheel. Use a sponge to keep the clay moist while you center it. Centering is the most critical step; if the clay is not perfectly centered, the vase will wobble and break. Press down firmly with both hands to align the mass vertically.
Opening and Raising the Walls
Once centered, open the clay by pressing your thumbs into the center and pulling them apart to create a uniform hole. Avoid opening too wide, as porcelain walls become thin quickly. To raise the walls, use a rib tool to compress the clay outward. Use gentle, upward strokes to pull the walls higher. Work in stages, adding small amounts of water to lubricate the rib. Keep the walls symmetrical by checking the shape from multiple angles. If the vase is tall, consider adding a handle or a foot ring for structural stability.
Refining the Shape
After reaching the desired height, refine the outer surface. Use a wooden rib to smooth out any ridges created during the raising process. For a classic vase silhouette, gently push the bottom in to create a curve and pull the top out for a flared rim. Remember that porcelain shrinks significantly during drying and firing, so make your vase slightly larger than your final desired size.
Drying and Bisque Firing
Allow the greenware to dry slowly. Cover it with a plastic bag for the first few days to prevent uneven drying, which leads to cracks. Once bone dry, place the vase in a kiln for a bisque firing at approximately 1,800 degrees Fahrenheit. This step makes the piece porous and ready for glazing.
Glazing and Final Firing
Submerge the bisqued vase into your chosen glaze. Porcelain shines best with transparent or celadon glazes that highlight its translucency. Ensure the foot is wiped clean to prevent the vase from fusing to the kiln shelf. Fire the glazed piece to a higher temperature, around 2,200 to 2,350 degrees Fahrenheit, depending on your glaze. This vitrification process makes the vase watertight and glass-like.
With careful attention to detail and proper firing techniques, your handcrafted porcelain vase will serve as a timeless decorative element in any home.
FAQ
Q: Why does my porcelain vase crack during drying?
A: Uneven drying speeds are the primary cause. Cover the piece with plastic to slow evaporation and avoid placing it in direct sunlight or near heat sources while it dries.
Q: What is the best glaze for porcelain vases?
A: Transparent glazes are ideal because they allow the white body to shine through. Celadon glazes also work well, creating a stunning blue-green hue in thin areas of the vase.
Q: How can I prevent the vase from sticking to the kiln shelf?
A: Always apply a thin layer of dry kiln wash to the foot of the vase before glazing, and ensure the kiln shelf itself is coated with a fresh layer of kiln wash.
