Ceramic mugs stainless steel cup glass cup for Microwave Oven

From Xinxiang Ceramic Mug Manufacturer,Now the microwave oven has entered millions of households and become a necessary kitchen helper, which brings great convenience to our life. However, many people are not very clear or misunderstanding about many related problems in actual use. What ingredients are suitable for microwave cooking? When cooking in a microwave oven, what kind of cutlery is the safest?

Dong Jinshi, vice president and secretary-general of the International Food Packaging Association, said in an interview with reporters that any material has a certain range of safe use. Containers that can hold food at room temperature may not necessarily be used in microwave ovens at high temperatures. When cooking in microwave oven, we should use tableware reasonably according to the characteristics of different materials, preferably glass or white custom ceramic mugs.

Glass material itself comes from nature. After high temperature, harmful substances have evaporated. It has high safety, high temperature resistance and good thermal conductivity, so it is suitable for microwave oven cooking.

Ceramic tea mugs custom have a wide range of applications, acid, alkali, oil, high temperature, low temperature, high safety, and can be used in microwave cooking. However, it should be noted that the paint on the color ceramic cups may contain harmful substances such as lead, cadmium and other heavy metals. According to the different decoration methods, ceramic cups can be divided into three types: glaze color, under-glaze color and in-glaze color. Underglaze and in-glaze colors are painted under the enamel. They are relatively safe because they do not contact food directly. The glazed ceramics are coated on the surface of the ceramics, which are in direct contact with food. The harmful substances lead and cadmium dissolve into food and enter the human body with food. If consumers can not clearly judge the glaze type of the ceramic cup, for safety, it is better to choose the ceramic container with white and colorless pattern inside.

Improper use of stainless steel tableware endangers human health

Nowadays, many consumers are very fond of stainless steel cups and tableware. Because their metal properties are good, they are more resistant to rust than other metals, and the made utensils are beautiful and durable, so they are more and more used to make kitchen utensils. However, stainless steel is made by adding some other trace elements into ferrochromium alloy. If improperly used, the trace metal elements will accumulate slowly in the human body. When reaching a certain limit, it will endanger human health. Here, experts remind consumers that when using stainless steel cups and tableware, they must pay attention to the following four points.

First, salt, soy sauce and hot soup should not be stored for a long time, because these foods contain many electrolytes. If stored for a long time, stainless steel, like other metals, will react with these electrolytes electrochemically to precipitate harmful metal elements.

Second, do not wash stainless steel tableware with strong alkaline or oxidizing chemicals such as soda powder, bleaching powder, sodium hypochlorite, etc. Because these substances are electrolytes, they will react with stainless steel chemically and produce substances harmful to human body.

Third, we should not use stainless steel utensils to boil Chinese medicine. Because traditional Chinese medicine contains many alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with them, and make drugs ineffective, and even produce some more toxic compounds.

Fourth, do not keep strong acidic food (such as melons, fruits, vegetables, soybeans, potatoes) for a long time in order to prevent the dissolution of chromium, nickel, and other metal elements.

Four Methods of Custom Ceramic Coffee Mugs Inspection

From Xinxiang Ceramic Mugs Manufacturers,Four Methods of Ceramic Coffee Mugs Inspection:

"Look" is to have a close look at the inside and outside of the porcelain. To see whether the glaze of porcelain can be bright and smooth, with or without scratches, holes, black spots and bubbles; to see whether the shape can be regular and deformed; to see whether the picture has no defects; to see whether the bottom can be flat, it must be placed smoothly and without burrs.

"Listen" is to listen to the sound of tapping on porcelain mugs. If the voice is loud and pleasant, it is clarified that the ceramic tire is fine and compact, without cracks, and when fired at high temperature, the porcelain is complete. If the voice is hoarse, it can be judged that there are cracks in the ceramic body, or that the porcelain is incomplete. This kind of porcelain is liable to crack when it is changed by heat and cold.

"Contrast" is analogy. For matching porcelains, we should compare various accessories to see whether their appearance and picture decoration can harmonize and diverge. Especially complete sets of blue-and-white or blue-and-white compact porcelain, because the color of blue-and-white varies with the firing temperature, so they are blue-and-white porcelain with shade and depth. A set of several or even dozens of complete sets of cold porcelain, such as each blue-and-white color has obvious differences, this set of porcelain is greatly inferior.

"Test" means test cover, test fitting and experiment. Some chinaware has a lid, and some chinaware is composed of several components. When choosing chinaware, don't forget to cover the lid and assemble the components to see if it is suitable. In addition, some porcelain utensils have special functions, such as dripping Guanyin, which can drip water automatically; Kowloon Fair Cup, when the wine is filled to a certain position, will all leak light. So we need to experiment to see if its function is normal.

The content of lead and cadmium in glaze, underglaze and most part of glaze and white ceramics in ceramic cups is very low, but if the underglaze color ceramics use inferior pigments in the processing of custom ceramic mugs flower paper, or use too much high amount of pigments containing lead and cadmium in the design of flower surface, or the temperature and ventilation conditions are not enough when baking, it is easy to cause the leaching of lead and cadmium to exceed the standard. Some white porcelain, mainly uncolored bone china, because of the use of lead-containing frit glaze, if the firing process is not strictly controlled according to the process conditions of bone china, lead dissolution is also very likely to exceed the standard.

Lead and cadmium in glazed and underglazed coloured ceramics are seldom or scarcely dissolved, so they can be purchased safely. If we pay attention to the quality control of various consumption links, the problem of excessive lead and cadmium can be controlled. From the past national surveillance and spot checks, not all products exceed the standard. The unqualified glaze decoration products mainly come from small enterprises of individual, private and family workshop type. The quality of products consumed and sold by large-scale consumer enterprises and regular dealers in big cities is comparable to that guaranteed.

Exports of ceramic mugs increased by 19.7% zibo china

From Xinxiang Ceramic Mug Manufacturers,In the first quarter of 2019, the total import and export volume of Zibo was 19.79 billion yuan, of which the total export volume was 10.37 billion yuan, an increase of 9.5% over the same period of last year, which was higher than the average export growth rate of the whole province by 18 percentage points. It is particularly noteworthy that the export volume of ceramics products of Zibo's characteristic industries in the first quarter was 630 million yuan, up 19.7% from the same period last year, which has become a new growth point of Zibo's foreign trade export.

It is understood that the export volume of custom ceramic coffee cups, architectural ceramics and decorative ceramics in Zibo in the first quarter was 175 million yuan, 258 million yuan and 202 million yuan, which increased by 12.9%, 28.8% and 61% respectively. The data show that although the proportion of export decorative ceramics in Zibo is relatively small, some ceramic processing enterprises in Zibo begin to export raw materials such as basic refractory soil, to export high value-added refractory ceramics, export machinery and equipment for processing refractory materials, products are constantly upgraded and the added value is gradually increased. The area along the route is an important destination for the export of ceramic products in Zibo. In the first quarter, it exported 230 million yuan to the countries along the route, accounting for 36.4% of the exports of ceramic products, an increase of 34.1% over the same period last year. Up to now, the export of "Zibo Made" ceramics products has covered 126 countries and regions such as the United States, Australia and India.

Which time is the best quality ceramic coffee mugs produced?

From Xinxiang Ceramic Coffee Mugs Manufacturers,Generally speaking, the best time for all ceramic products (including ceramic cups) to be shipped is from May to October every year (the best time for consumption of ceramic products). The color and qualified rate of all ceramic cups are the best. The most important reason is the weather. Porcelain embryos are easy to dry. The oxidized impurities in the kiln will be reduced to the lowest level. There will be no black spots on the ceramic cups. Plus this period is the weak period of the ceramic market, the price of porcelain is very cheap, and the waste of ceramic cups is the best time to buy Ceramic cups.

The most difficult time to produce custom ceramic coffee cups is from November to February every year (yellow cycle of ceramic products). Because of the cold and humid weather and the high humidity, it is difficult to dry the ceramic embryos. Some air passages in the ventilated pipes of the kiln will produce oxidation, and the black spots (usually iron) will fall on the fired porcelain. In addition, the cold weather affects the working efficiency and quality of workers. Then there are glazing, and other details of the problem, the quality of the ceramic cup has a direct impact.


There are also some logistics transportation costs, glaze, labor costs, kiln costs and so on during this period of time are rising (weather times consume a lot). Especially in the past two months, every company will be busy. These various reasons combined will form a period of ceramic cups expensive, and the quality of production is not as good as between May and October, so when is the best time to buy Ceramic cups, of course, from May to October every year.

How to Choose Correctly Ceramic Coffee Mugs

From Xinxiang Ceramic Mug Manufacturers,Ceramic mugs have various shapes, delicate lubrication, bright colors and are easy to clean. However, lead, mercury, radium, cadmium and other elements in the glaze are harmful to health. Therefore, when purchasing and using ceramic cups, we should pay attention to the following points:

1) Ceramic mugs must be purchased in a proper market, and inferior products without formal consumer ceramic mug manufacturers must not be purchased cheaply. According to the national rules, when ceramic tableware is immersed in 4% acetic acid, the leaching amount of lead should not exceed 7 mg/l, and the leaching amount of cadmium should not exceed 0.5 mg/l.

2) When purchasing, we should pay attention to the fineness of the tableware, touch the appearance of the Ceramic mugs with our hands, and see if the inner wall is bright.

3) Whether there is a peculiar smell or not;

4) Don't buy ceramic tea cups with too bright colour. Usually, the brighter the color of tableware, the more easily heavy metals exceed the standard;

5) Purchase of glazed and underglazed ceramic cups with strict raw materials and process control.

6) Boil the ceramic cup in boiling water for 5 minutes before use or soak it in vinegar for 2-3 minutes to dissolve toxic substances.
