Key Takeaways
- Porcelain is a durable, non-porous ceramic made from clay, quartz, and feldspar, fired at high temperatures.
- Originating in China 2,000 years ago, refined Chinese porcelain was widely known as 'China' in Europe.
- Europeans took centuries to replicate porcelain, with Johann Friedrich Böttger reverse-engineering the process in the 18th century.
- Porcelain's impermeability is inherent from vitrification during firing, not primarily from decorative glazing.
- Bone china, an English innovation, uses animal bone for strength but is less durable than hard paste porcelain.
Deep Dive
- Porcelain is a durable, high-performance subset of ceramics, distinct from more delicate types.
- It is composed of natural materials like clay, quartz, and feldspar, with kaolin being a common white clay.
- Fired at high temperatures, up to 2,300 degrees Fahrenheit, it becomes denser, non-porous, and impermeable.
- Porcelain originated in China around 2,000 years ago during the Tang dynasty.
- Refined Chinese porcelain, introduced to Europe by Marco Polo, was widely called 'China' due to Europe's inability to replicate it.
- Europeans took several centuries to discover the process, with German alchemist Johann Friedrich Böttger credited in the 18th century.
- Hard paste porcelain is denser and more durable, fired at higher temperatures.
- Europeans more commonly used soft paste, which is prone to chipping and has a grainier texture.
- Porcelain's impermeability is an inherent quality due to vitrification during firing, not primarily due to decorative glazing.
- 'Bisque' refers to unglazed porcelain.
- Porcelain tile is a hardy material suitable for floors and walls, often requiring a wet tile saw for cutting.
- It is formed using special molds for sizes up to four by four feet or by compacting ceramic powder layers for larger dimensions.
- Chinese porcelain can achieve extreme value, exemplified by a Mayantang chicken cup selling for $36 million in 2014.
- This value is tied to rarity, peak quality periods (1465-1487), and durability over thousands of years.
- Bone china, an English development, incorporates farm animal bone to strengthen the ceramic but is fired at lower temperatures, making it less robust than other types.
