The coloring process of ceramic tableware is a crucial step in its production, as it not only enhances the aesthetic appeal but also improves functionality and durability. Below are the main steps in the coloring process:

1. Glaze Preparation
   Before coloring, suitable glaze must be prepared. The glaze can be transparent, semi-transparent, or opaque, and various pigments can be added to create different colors.

2. Biscuit Firing
   Before coloring, the ceramic body undergoes biscuit firing (the first firing) to harden it and provide sufficient strength for the subsequent coloring process.

3. Glazing Methods
   There are several methods for applying glaze, including:

   • Dipping: The body is dipped into the glaze to ensure even coverage.

   • Spraying: A spray gun is used to evenly coat the body with glaze.

   • Brushing: Glaze is manually applied with a brush, suitable for partial coloring or intricate designs.

4. Drying
   After glazing, the body must be dried again to ensure the glaze adheres evenly, preventing cracks or bubbles during firing.

5. Glaze Firing
   The glazed body is fired in a kiln at high temperatures, known as glaze firing. The temperature typically ranges between 1200°C and 1400°C, allowing the glaze to fully fuse with the body and create a smooth, durable surface.

6. Decoration and Painting
   For more complex patterns or designs, painting can be done after glaze firing. Non-toxic pigments are usually used, and a low-temperature firing is required to fix the colors.

7. Quality Inspection
   The colored ceramic tableware undergoes strict quality checks to ensure even coloring, no defects, and compliance with food safety standards.

The coloring process of ceramic tableware not only enhances its beauty but also improves its practicality and durability, making it a work of art for the dining table.
