Is it bone china, fine china, or porcelain? Find out with these tips

If you’ve been looking into plates and dinnerware for the perfect dinner table, you may have heard of bone china and porcelain. What’s the difference? And why are dishes called china?

Porcelain and bone china are two different types of ceramics that are very similar. You may have seen these types of dishes in your grandma’s house, or maybe you received some for your wedding. Or perhaps, you’re interested in hopping on the grandmillenial trend, which incorporates these plates and dishes. In any case, knowing the differences in your dinnerware materials could influence your decision when it comes to using them in your home.

The short of it all is that both kinds of ceramics are very nice dinnerware usually used on special occasions. Whether you have your own or recently inherited some, you probably want to know what kind of dishes you have. Many people can’t tell the difference when it comes to bone china vs. porcelain just by looking at it, but there are some significant differences beyond what meets the eye. Here are the biggest differences and how you can tell them apart.

What is Bone china, and what makes it unique?

Bone china gets its name because it’s made with bone ash. Bone ash is precisely what it sounds like — animal bones —  usually, cow bones, ground into an ash consistency. Bone china has a specific percentage of bone ash, generally between 30% and 45%, mixed into the other ingredients that can include quartz, kaolin (a type of clay), feldspar, ball clay, silica, and more. The mixture is then sculpted or molded into the desired shape and prepared for firing.

Firing is the process that ceramics go through to harden them to be used for food and drink. Bone china is unique in that it can withstand being fired twice in the kiln, which is the oven used for firing ceramics. The first phase of firing causes the piece of bone china to shrink, and the second phase sets the glaze to the china so it becomes one. Typically, bone china is fired at a maximum temperature of 2,228 degrees Fahrenheit (1,220 degrees Celsius).

What is porcelain?

Porcelain is different from bone china for one main reason: It doesn’t contain any bone ash. The ingredients for porcelain have varied throughout history and region, so it may be difficult to tell exactly what your porcelain dishes are made of unless you know when and where they were made. European porcelain is usually made of clay, ground glass, feldspar, and other materials, whereas Chinese porcelain is made of pegmatite granite and kaolin.

The main difference between bone china and porcelain, other than ingredients, is that porcelain is harder than bone china and is fired in a kiln at a higher temperature. Porcelain is fired at approximately 2,650 degrees Fahrenheit (1,454 degrees Celsius).

How is fine china different from other ceramics?

Fine china is neither bone china nor porcelain, but yet another type of ceramic that exists to confuse matters even more. Fine china does not have bone ash in it, and it is not fired at a temperature as high as porcelain, so it is a different category of ceramics. The main difference between porcelain and fine china is that fine china is not as durable as porcelain due to the lower temperature that it is fired.

Bone china vs. porcelain: what is the difference?

At a glance, you may not be able to tell the difference between bone china, fine china, and porcelain. However, if you look closely, bone china will not be as bright white as fine china or porcelain.

  • Bone china has a more off-white color than porcelain.
  • Porcelain is also more durable and feels heavier in your hand than bone china.
  • Typically, the words “bone china” are marked on the bottom of a piece of bone china.
  • If you hold china up to a light, you will see that bone china is more translucent than fine china.

Knowing these tips and tricks for identifying these materials will not only help you to differentiate between their unique styles but will also enable you to take better care of your dishware. These materials can sometimes require special attention and often have varying needs regarding maintenance. So, knowing what type of ceramics you have can make a big difference in how you choose to use them in your home.

No matter what kind of ceramic dishes you have, you should break them out of their storage place and use them once in a while. Sure, they may be family heirlooms, but what good are fancy dishes if you never show them off?
