White porcelain, often referred to as bone china or fine china, is a type of ceramic material that is known for its delicate appearance and high strength. It is prized for its translucency and is commonly used in high-quality dinnerware, decorative objects, and art pieces.
What is White Porcelain Called?
White porcelain is typically called bone china or fine china. These terms are often used interchangeably, though they have distinct characteristics. Bone china is renowned for its durability and whiteness, achieved through the addition of bone ash to the clay mixture. Fine china, while similar, may not contain bone ash but still offers a refined, elegant appearance.
How is White Porcelain Made?
The creation of white porcelain involves a meticulous process that includes:
- Raw Materials: The primary ingredients are kaolin (a type of white clay), feldspar, and quartz. For bone china, bone ash is also added.
- Mixing: These materials are mixed to form a smooth paste or slip.
- Shaping: The slip is poured into molds or shaped on a potter’s wheel.
- Firing: The shaped items are fired at high temperatures (above 1,200°C or 2,192°F) to achieve vitrification, which gives porcelain its glass-like quality.
- Glazing: A glaze is applied to the surface to enhance its shine and waterproof properties.
- Second Firing: The glazed items undergo a second firing to set the glaze.
Why is Bone China Considered Superior?
Bone china is often regarded as superior due to its unique composition and qualities:
- Strength and Durability: The addition of bone ash increases the strength of the porcelain, making it more chip-resistant.
- Translucency: Bone china has a distinct translucency, allowing light to pass through, which gives it an elegant appearance.
- Whiteness: The presence of bone ash results in a whiter, more luminous finish compared to other types of porcelain.
Common Uses of White Porcelain
White porcelain is versatile and used in various applications:
- Dinnerware: Plates, bowls, cups, and saucers are popular items made from bone china due to their aesthetic appeal and durability.
- Decorative Pieces: Vases, figurines, and ornaments often utilize fine china for its ability to hold intricate details.
- Art: Artists use porcelain as a medium for creating sculptures and installations.
How to Care for White Porcelain?
Maintaining the beauty of white porcelain requires careful handling:
- Washing: Hand wash with mild detergent and avoid abrasive scrubbers to prevent scratches.
- Storage: Store items with padding between them to prevent chipping.
- Temperature: Avoid sudden temperature changes, as they can cause cracks.
