Quality Standard of EUNA Ceramic Tableware

At present, about half of the disposable dishware used in the country is unsafe, with excessive amounts of chemicals that can cause cancer. Therefore, it is safer and healthier to use ceramic tableware than to use disposable tableware. But if you buy ceramic tableware that neither uses safe ingredients nor undergoes rigorous quality checks, it can also pose a health risk to you and your family.

However, EUNA can confidently assure you that each and every piece of our tableware is free from safety problems! In this article, we will introduce you the strict quality standards of EUNA tableware.

Quality Standard of EUNA Ceramic Tableware

Many countries in the world have put forward more strict quality and safety requirements for daily ceramic tableware products. There are many factors that could result in the hazard if anything goes wrong during the production process. So in EUNA, the main technical indicators for evaluating daily ceramic tableware include the following aspects, appearance quality, and safety indicators.

Appearance Quality

Appearance quality is an important criterion for the quality classification of ceramic tableware. The inspection of appearance quality includes errors in capacity, caliber, height, weight, and defects. How many different types of visible and non-visible defects, these are indicators to be measured when determining the appearance quality of ceramic tableware. EUNA requires that the same batch of tableware products should be the same caliber, height, weight.

Therefore EUNA excellent products can easily reach the international advanced level - the appearance quality of premium products requires high quality and little deformation.

Safety Indicators

In EUNA, the safety indexes in the quality of ceramic tableware mainly include lead and cadmium release, thermal stability, dishwasher stability, microwave oven stability, radioactive material content, and potential pollution to the environment.

  1. Lead and cadmium release

Lead and cadmium release is not only an important safety and health index of daily ceramic tableware products, but also a very concerning issue, the amount of lead and cadmium directly affects the health of users.

The presence of lead and cadmium is due to the raw material, the firing environment, surface decoration patterns, the presence of lead due to the composition of the ceramic pigments in the patterns, and possibly the addition of lead due to the low firing temperature of the surface glazes of the products, improper control of the production process can easily lead to excessive release of lead and cadmium in the process of use.

Therefore, EUNA only purchases non-toxic and non-hazardous glazes, and strictly checks the production process and firing temperature of the pottery to avoid harmful substances from remaining on the tableware.

  1. Thermal stability

Thermal stability is referring to the exchange of the product in the heat and cold suddenly without cracks or damage. The quality of thermal stability can reflect the service life of ceramic tableware products. The larger gap in the temperature of heat and cold exchange, the longer the service life of the ceramic tableware products.

The standard testing method generally refers to putting the products in the hot water of 180 degrees, and taking out and then putting in 20 degrees water and taking out, observing whether there is any damage.

  1. Safety testing of microwave ovens

The test method of microwave-safe measures whether the electric arc is produced in the microwave heating process and if damage occurs and the maximum surface temperature of the daily ceramic product after microwave heating under the condition of moisture.

  1. Safety testing of dishwashers

In this test, the unused sample is placed in a static solution of a specific alkaline detergent at 75±1 degrees for serveral hours, and then the sample is visually examined and compared with similar untested samples to determine the color and glossiness, to see if there is any change due to the detergent.

  1. Products environmental technical requirements

The standards stipulate that the pollutant discharge of the product production enterprises must meet the requirements of the national or regional pollutant discharge standards. EUNA also strictly adheres to these standards and strives to minimize the contamination generated during the production of tableware, since we are becoming more aware of the need to protect our environment.


The above is EUNA's product quality testing standards. The reason why our product quality testing is so strict is that EUNA only wants to provide you and your family with the safest and the most lavish tableware, bringing pleasure and elegance to your life and your family's dinning experience!
