Ceramic vs. Porcelain – How are they different?

Of all the intricacies of all mechanical components used in the making of clocks, pottery and clay are probably the least discussed. Not expensive brands like Rolex, Omega, IWC or Hublot of choice; earthenware is selected by the type of precious metal as well!

In the past, we have briefly discussed pottery, but we had left some clay. We had to cover these things after the molds; since we have not, we will now. Otherwise, watches like Seiko Presage Arita Porcelain Automatic will not show up and many watchmakers will miss out on the joy of having a unique piece.

Ceramics – Repetition

Ceramic can be durable, heat-resistant and non-abrasive, made of non-metallic materials – such as clay – and burned at high temperatures. Clay, ceramic and brick – all under ceramic flooring.

That way, the head does not just stand still; let’s say it’s a clay issue.

Ceramics vs. Porcelain: How is it different?

As mentioned earlier, the topic did not stop – however, if we have to; the difference between the two devices is based on their properties and function; The main differences in clay – a type of clay material – include steps that heat the mold to a very high temperature (12000C to 14000C) to find the items you want. Therefore, porcelain; are more expensive than ordinary raisins.

Porcelain production process consists of six main steps, starting with breaking and grinding the equipment to the desired thickness, hydration (water addition) to the desired production system and then shooting it. First, the temperature remains too low to ripen the decaying material. It also reduces shrinkage during shooting. This is called glazing. Next and final is the firing, which takes place at high temperatures.

Ceramic uses clay, clay materials, flour and water as tools. They are well mixed and given the shape and form they want. They are burned at high heat in a furnace, covered with decorative, waterproof or glaze.

Porcelain itself has vitreous / glass properties, one person translucence. It allows light to pass but divides as it passes. Adds fog to objects on the other side. Porcelain also has low porosity.

The composition of the clay

The materials used to make porcelain vary depending on the purpose for which it is used. In particular, it is Kaolin; the very rock kaolinite – clay salt containing aluminum silicate – also comes from. The presence of clay salts in Kaolin adds to its plasticity. Kaolin brings important features to many other applications. These include paper, paint, fiberglass, cosmetics and chemicals.

Porcelain can also be made from

  • Feldspar: Solid crystalline minerals containing aluminum and silicates of potassium, sodium, calcium or barium.
  • Steatite: Soft and heavy forms of talc (hydrated magnesium silicate) with soap.
  • Quartz: Silicon dioxide in crystal form. Quartz containing iron oxide and yellow sand.
  • Petuntse / Blessings: Many types of micaceous (hydrous silicates related to or similar to mica) or feldspathic rocks. China clay requirements.
  • Alabasitala: Kalcite / gypsum is durable, compact, well-formed, usually clean and is used for carving.
  • Clay ball: Kaolintic sedimentary clay, usually made kaolinite (20% -80%), mica (10% -25%), quartz (6% -65%).
  • Glass: We all know what it is, we should not waste time or words on it.
  • Bone ash: The calculation yields white ash from the bones, containing approximately 55.82% calcium oxide, 42.39% phosphorus pentoxide and 1.79% water, the exact form depending on the type of bone used. It has a melting point of 1670 ° C or 3038 ° F. Most bones store their cells through calcinations.

Often, several sources are mixed to form; For example, See China (bone ash, feldspathic substances and kaolin). Porcelain is defined as – ware and translucent body.

See China should contain 30% phosphate derived from animal bones and calcium phosphate accordingly. It is the strongest member of the porcelain family (Chinese pottery) and allows for thinner layers than other types of clay. It has mechanical and physical strength as well as chip resistance. It also has the highest levels of purity and transparency.

The next day, we will discuss the Seiko Presage Arita Porcelain Automatic in depth.
