TL;DR: You can create elegant porcelain home decor by pouring slip into molds, drying the pieces, and firing them in a kiln. This guide walks you through seven steps, from preparing your workspace to applying a protective glaze.
Step 1: Gather Materials
Collect porcelain slip, plaster molds, a kiln, glaze, mixing buckets, and fine sandpaper. Work in a well-ventilated area.

Step 2: Prepare the Mold
Clean your plaster mold and secure it with rubber bands. Dust the interior lightly with talc for easy release.
Step 3: Pour the Slip
Fill the mold to the top with well-mixed porcelain slip. Let it sit for 10–15 minutes to build wall thickness, then pour out the excess.
Step 4: Unmold and Clean
Wait until the piece is leather-hard, then gently remove it. Smooth seams with a damp sponge and refine edges with a fettling knife.
Step 5: Bisque Fire
Let the piece dry completely, then fire it in a kiln to cone 04 (about 1945°F). This hardens the porcelain for glazing.
Step 6: Glaze the Piece
Dip, pour, or brush glaze onto the bisque-fired decor. Keep the bottom clean to prevent sticking. Let the glaze dry fully.
Step 7: Glaze Fire and Finish
Fire to cone 6 (about 2232°F). Once cool, sand any rough spots and display your finished porcelain home decor.
FAQ
Q: Can I make porcelain decor without a kiln?
A: No, porcelain requires high-temperature firing. Use air-dry clay for no-kiln projects.
Q: How thick should porcelain walls be?
A: Aim for 3–5 mm for small decor items; thicker walls may crack during firing.
Q: What glaze works best for porcelain?
A: Food-safe, lead-free glazes designed for cone 6 are ideal for vases and dishes.
