Porcelain glazing is a transformative process that elevates ceramic sculptures from raw clay to luminous artworks. The most common techniques include:

1. Underglazing: Applied before firing, underglazes offer precise color control and matte finishes. Artists layer them for depth, often combining them with clear glaze for durability.

2. Overglazing: Added after the initial firing, overglazes create glossy, glass-like surfaces. This technique enhances vibrancy but requires careful application to avoid dripping.

3. Dipping/Casting: Submerging sculptures in glaze yields even coatings, ideal for uniform pieces. Variations emerge based on viscosity and dipping duration.

4. Spray Glazing: Airbrushing allows gradient effects and delicate transitions, favored for contemporary pieces requiring subtle tonal shifts.

5. Wax Resist: Wax blocks glaze absorption, creating contrasting textures. When fired, the wax burns away, leaving raw porcelain exposed for dramatic effects.

Each method impacts aesthetics differently: Underglazing preserves intricate details, while overglazing amplifies reflectivity. Dipping ensures consistency, whereas spray glazing enables artistic nuance. The firing temperature (typically 1200-1400°C) further alters outcomes—higher heats fuse glazes more seamlessly but may limit color options.

Mastering these techniques empowers artists to manipulate light absorption, texture, and durability, turning porcelain sculptures into captivating visual narratives.
