Among the tableware we use, many are made of porcelain, but people may not know that there are many types of porcelain, among which bone china and pottery are the most common. Since they are tableware, we have to consider health issues, so which is healthier, bone china or pottery? Bone china is lighter and thinner than porcelain. For example, when comparing the same type of bone china and porcelain, bone china will be much lighter. Moreover, bone china appears whiter than porcelain. Bone china tableware is mostly milky white and very bright, while porcelain tableware is dark gray.The glaze on ceramic bowls contains heavy metals like lead and chromium. If the quality of the glaze is poor, it can easily lead to excessive heavy metals, which can harm human health with long-term use.The specific differences are as follows:

1.Different materials
Ceramics are made from natural clay and various natural minerals as the main raw materials. Porcelain with a bone ash content of more than 25% is bone china.

2.Different processes
Bone china is fired using a two-step firing process, with temperatures between 1200 and 1300 degrees Celsius. General ceramics can be formed at 900 degrees Celsius.

3.Different weights
Due to the high hardness of bone china, its shape is much thinner than general ceramics. Therefore, bone china of the same volume is much lighter than ceramics.

4.Insulation effect
Compared with traditional ceramics, bone china has better insulation, providing a better taste when drinking coffee or tea.

Bone china with a bone ash content of more than 45% is usually harder, lighter, and whiter than ordinary ceramics. It normally appears milky white. Bone china does not crack when it is exchanged between 180°C and 20°C water; but it is best not to deliberately frequently heat and cool during use. Due to thermal expansion and contraction, ceramic products are prone to cracking.

Which is healthier, bone china or ceramics?

Generally speaking, bone china is more beneficial to health. The differences in materials and processes between bone china and ceramics determine their grade gap. The production of bone china mainly selects animal bone ash, and its content is as high as 40% or even more. The current world's highest bone ash content is the British royal family's boutique bone china tableware with high-quality bone ash up to 50%. In addition, bone china's flower surface and glaze surface are fused into one, and it does not contain lead and cadmium that are harmful to the human body. It can be called a real "green environmental protection porcelain".

Which is better, bone china or ceramics?

If we simply talk from the perspective of health and durability, obviously bone china is better, but an important factor we cannot ignore is the price. The price of ceramics is often lower than that of bone china, so we need to consider multiple aspects and choose what meets our requirements and preferences.

How to distinguish between bone china and ceramics?


1.Look at the color. The color here refers to the color of the body part of the bone china that does not cover the flower surface. The real high-quality bone china with a high content of bone ash should be milky white or called milky white. Note: Bone china is not the whiter the better, natural milky white is good bone china;

2.Transparency. Hold the bone china in your hand and observe it. Good bone china has a natural milky white color unique to natural bone ash. Observe the transparency of the bone china against the light, and see whether the composition of the cup is fine or not. Good bone china should be more transparent and uniform without impurities.

3.Touch the bottom of the bowl. Why touch the bottom of the bowl? Because the bottom of a finely crafted bowl has been polished twice, it is both non-slip and prevents scratching the table. This is a test of a porcelain's craftsmanship from the details;

4.Collision. Bone china looks very thin and gives a very fragile feeling. In fact, the hardness of bone china is about three times that of ordinary ceramics. Normally take two small bowls, hold the bottom of the bowl, and bump them together. You will hear a long and pleasant echo. If it is not bone china, it will either be turbid or short.
