As bone China products are fired at least 2 times, sometimes 3 or even 4 times at high temperature, the firing time is up to 8 hours or more, the highest temperature of firing up to 1350 °C. So under normal circumstances, it is safe to put bone china in the microwave oven heating.

When can I put bone china tableware in the microwave?

So, when is bone China not allowed to be heated in the microwave oven?
The answer is when bone China has gold in its decorative surface.

If the surface of bone china is decorated with gold border and gold pattern, once we put the bone china products in the microwave oven, when it’s working, the gold layer on the bone china surface will generate a strong electric spark under the intense microwave radiation.

The radiation will seriously damage the gold layer and lose the yellow brightness, and the sparks would cause panic and danger, which will matter more than just ruining the bone china tableware.

The answer is to see with your eyes.
The use of gold makes the cutlery shine and makes it look more beautiful. There are two colors of gold, platinum and gold. And there are two main ways to decorate with gold. One is a line drawn in gold water, the other is in the designs, in addition to color pigments, but also the adding of gold.

The difference in gold content and making method.
The liquid gold used to decorate the ceramic products is a chemical raw material.

The main ingredients are acid, gold, silver, bismuth, resin, Turpentine, essential oil and other components, according to a certain proportion of the formula, and formed by complex chemical reaction. It often has an appearance like brown oil and liquid.

While precious metals are the main component of gold, due to international gold price fluctuations, while the price of gold is different every day, so is the price of liquid gold for ceramic decoration.
The higher the gold content, the brighter the fired products, also the price would be higher.

To solve the problem that the products with gold can not be heated in the microwave oven, more and more people choose to use microwave gold instead of ordinary gold to make the dough. Compared with ordinary gold, microwave gold is relatively dull in color and looks less attractive than ordinary gold.
