Porcelain

Porcelain is a ceramic material made by heating raw materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength, and translucency of porcelain arise mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures.

In the tableware industry, porcelain is considered the standard for both professional hospitality and domestic use due to its exceptional durability and non-porous nature.

1. Key Characteristics

2. Hard-Paste vs. Soft-Paste Porcelain

Type Composition Characteristics
Hard-Paste Kaolin + Petuntse (Fieldspar) The “true” porcelain. Extremely hard, glassy, and resonant.
Soft-Paste Mixtures of clay and ground glass Developed in Europe to mimic Chinese porcelain; less durable than hard-paste.

3. Porcelain vs. Bone China: Which to Choose?

While often confused, the two materials serve different needs:

4. Professional Use (HORECA)

Porcelain is the preferred material for the HORECA (Hotel, Restaurant, and Catering) sector because:

  1. It is Stackable: Designed with reinforced edges for heavy-duty use.
  2. It is Microwave & Oven Safe: Ideal for reheating and professional kitchen workflows.
  3. It is Dishwasher Safe: Resists the abrasive chemicals used in industrial dishwashers.

5. Notable Manufacturers

Maintenance Tip: To keep your porcelain looking new, avoid using metal scouring pads which can leave “metal marks” (grey streaks) on the glaze. Use specialized cleaners if these marks appear.
