The material of 14oz white ceramic coffee mugs

 From Xinxiang Ceramic Mugs Manufacturers,The beautiful pattern of 14oz white ceramic coffee cup is glaze color, and the method of glaze color determines the safety of ceramic tableware. Glaze is divided into overglaze color, underglaze color and underglaze color, and only overglaze color is not safe.

The resolution method is very simple, the surface is smooth, such as the amount of lead and cadmium dissolved in the glaze and underglaze color ceramics of glass is very little or almost no, so you can buy it at ease; and for the surface of the glaze color products with concave convex feeling, you should try to choose the products with less surface decoration patterns. Secondly, if the overglaze color ceramic is touched by hand, the surface of the product has concave and convex feeling, and the height is uneven when observed by naked eyes; if the underglaze color ceramic and the underglaze color ceramic touch the surface of the product by hand, it is smooth as glass, without the feeling of uneven. Among them, most of the glaze color and underglaze color porcelain can be purchased at ease; and if inferior pigments are used in the processing of the glaze color porcelain, it is easy to lead to excessive dissolution of lead and cadmium. If you buy a product that you don't trust, soak it in vinegar for a few hours. If you find that there is a significant change in color, you should discard it. In addition, the raw material soil of ceramic firing is different in mineral content due to different producing areas, while the soil with high content of silicon and mercury is not suitable for cooking tableware.

Consumers should pay attention to whether the pattern color is bright when choosing the glaze color products. If not, the amount of lead and cadmium dissolved is often high. Don't be greedy to buy three no ceramics on the street. It's hard to guarantee the safety of 14oz white ceramic coffee mugs on the street, because it has no brand and production standard at all. If economic conditions permit, we should also choose the lead-free glaze "green" tableware which is more expensive than ordinary ceramic tableware, which can be bought in supermarkets. For example, Bone China is recognized as a high-grade porcelain in the world. Its high calcium oxide content is due to the selection of animal bone powder as one of the raw materials. White porcelain bone china does not contain lead, cadmium, and the picture is not easy to wear. It is also suitable for the use of microwave oven. It is worthy of "green" ceramics.

Harm of cadmium and lead in ceramic coffee mugs china

 From Xinxiang Ceramic Mug Manufacturers,Ceramic coffee cup, as we all know, the traditional concept of ceramics refers to all the artificial industrial products with clay and other inorganic non-metallic minerals as raw materials. It includes various products made of clay or mixture containing clay through mixing, forming and calcining, which are called ceramics.

Ceramic coffee mugs has become the first choice of tableware for many families because of its smooth color, bright color and exquisite design. But few people know that in order to ensure bright colors in the production process of ceramic cups, lead, mercury, radium, cadmium and other harmful heavy metal elements are usually added to the colored glaze.

However, if milk and other foods containing organic acid are placed in custom ceramic coffee cups with heavy metal exceeding the standard, the toxic substances in the ceramic cup will be released and enter the human body together with the food, causing chronic poisoning, in which cadmium and lead may cause liver or other internal organs poisoning, mercury may cause liver and kidney hardening, and radium may kill white blood cells. In addition, in addition to the colored porcelain, the white porcelain without colored glaze may also have excessive heavy metals. If the clay used to make the porcelain is unqualified, lead poisoning and other diseases may be caused.

Therefore, when purchasing ceramic cups, we should carefully observe whether the inner wall of tableware is smooth and clean, and use nails to scrape. If there is a pattern on the ceramic cup and the part without a pattern has different refraction light, the two parts have different handfeel, and the glaze color can be scraped off with nails, it is likely that the inferior products with excessive heavy metal can not be used to hold food. At the same time, in order to ensure safety, the ceramic tableware should be boiled for 5 minutes before use, or soaked in vinegar for 2-3 hours to dissolve the harmful substances in the customed ceramic tablewares. In addition, white porcelain should be soaked in white vinegar, and colored porcelain should not be heated in microwave oven. Why the color porcelain should not be heated in the microwave oven, because the color painting on the inner wall of the color tableware is bright, but the color glaze contains lead, mercury, cadmium and other heavy metal elements. Among them, cadmium and lead are easy to cause liver or other visceral poisoning, while Mercury can cause liver and kidney sclerosis. The more the glaze color of the ceramic cup, the brighter the color, the more lead, cadmium and other compounds.

It is understood that in the production process of ceramic cup, lead is added to the glaze and lead and cadmium are added to the pigment, which can make the glaze uniform and bright. However, there are serious defects in the raw materials and processes of some small ceramic production workshops. In order to pursue low cost, the physical and chemical indexes of daily ceramic products, especially the indexes of lead and cadmium, often do not meet the product quality and safety standards.

Therefore, the industrial and commercial personnel remind consumers: when purchasing ceramic products, they should pay attention to whether the pattern color is bright. If it is not bright, it may be that the temperature does not meet the requirements when baking flowers, and the amount of lead and cadmium dissolved in such ceramic products is often high. Especially those ceramic tableware that can wipe off the pattern by hand, it is better not to buy.

Glazed technology of custom ceramic coffee mugs china

From Xinxiang Ceramic Mugs Manufacturers,To judge whether the ceramic tableware contains toxic substances, it is necessary to distinguish which kind of ceramic coffee cup is used: underglaze color, underglaze color and overglaze color.

How to distinguish overglaze color, in glaze color and underglaze color?

Generally speaking, ceramic tableware is toxic, which belongs to the category of glaze color. Because the patterns or patterns on the glaze color tableware can be scraped off with a knife, or even soluble in water, and the pigments used to make patterns or patterns are toxic.

OK, there's a problem. If the patterns or patterns on the tableware are on the surface of the tableware, those that can be scraped off with a knife or sharp tool are likely to eat toxic substances in the process of use.

So when people choose custom ceramic coffee cups factory, they should be optimistic. Don't buy glaze colored tableware. Don't be attracted by its low price. You need to know that health is priceless and can't be bought by money. It's good to spend more money to buy health and rest assured. You just choose underglaze or underglaze.

How to judge the quality of ceramic coffee mugs by watching and listening

From Xinxiang Ceramic Mugs Manufacturers,How to judge the quality of ceramic coffee mugs by watching and listening.

In daily life, we deal with ceramic tableware every day, so how to identify the quality of ceramic coffee cup? The two most important keys to distinguish ceramic tableware are "look" and "listen".

1. "Look" is to observe the inside and outside of the ceramic coffee cups carefully. First, check whether the glaze of porcelain is smooth and smooth, and whether there is scratch, small hole, black spot and bubble; second, check whether the shape is regular, and whether there is deformation; third, check whether the picture is intact; fourth, check whether the bottom is flat, and must be placed stably, without burr.



2. "Listen" is to listen to the sound when you gently tap the ceramic coffee mugs. If the sound is clear and melodious, it means that the porcelain body is fine and dense without crack damage. When it is fired at high temperature, the porcelain is complete. If the voice is dumb and dull, it can be concluded that the porcelain body is cracked or incomplete. This kind of porcelain is easy to crack after cold and hot changes.



In addition, do not buy Ceramic tableware with too bright colors. In order to make the color bright, the manufacturer will add some heavy metal additives to the glaze color. Therefore, the brighter the color of the tableware, the more likely the heavy metal will exceed the standard. Long time use of such tableware will cause chronic poisoning.



Recently, I saw a lot of people saying bad things about custom ceramic coffee mugs  on the Internet, saying that ceramic tableware is not good and contains toxic substances, which should be used as little as possible or not. I think people who say these words are all idiots and lack of common sense. People in the United States and Europe regard ceramic tableware as a symbol of family life, but some people here don't understand anything and say that ceramic tableware is poisonous. They are really angry.

Healthy use of color glazed ceramic coffee cups and tableware from china manufacturers

From Xinxiang Ceramic Mugs Manufacturers,Paper cup: the outer layer is mostly attached with plastic film or wax. It is not suitable to hold the food just out of the pot.

Ceramic cup: ceramic cup, health and threat coexist

Ceramic mugs custom is one of the tableware that almost every family will use. Although ceramic tableware is relatively safe, the lead content in ceramics is inevitable in the manufacturing process. In addition, it may contain cadmium, mercury, radium and other elements. In the long-term and improper use, it is easy to cause chronic poisoning. Cadmium damages the kidney greatly and accumulates in the bone, which leads to the decrease of human immunity, joint deformation and pain.

Purchase and safe use: lead, cadmium and other elements in ceramic tableware mainly lie in glaze color. However, glaze color porcelain is easy to be identified by visual inspection and hand touch. If the picture is not as bright as glaze, the hand feel is not smooth or even the edge of the picture is convex, you should be careful. The newly purchased ceramic cup can be boiled in boiling water for 5 minutes before use, or soaked in vinegar to release most toxic substances. When using, do not use colored ceramic tableware to contain acid food.

Enamel cup: contains lead compounds such as lead silicate, which will be harmful to human body if not processed well. To buy enamel tableware, we should choose high quality products with exquisite workmanship.

Plastic cup: containing carcinogens of vinyl chloride, long-term use can cause cancer.

Glass: sometimes "moldy", with soap and other alkaline substances can be removed after washing.

Aluminum cup: Aluminum accumulates too much in human body, which will cause arteriosclerosis, osteoporosis, dementia, etc. Therefore, it should be noted not to use a rice shovel to scrape the aluminum pot. In addition, it is not suitable for long-term storage of food and long-term storage of salty food.

Copper Cup: after rusting, it will produce "copper green", i.e. copper carbonate and blue alum, which are harmful substances, which can cause nausea, vomiting and even serious poisoning accidents.

The knowledge of fine porcelain ceramic coffee mugs

So the key point of selection is: to see whether its utensils are out of shape, and then whether the painting process is fine.

Choice of strengthening porcelain

Mainly to see if the utensils are deformed; Bone China purchase: one heft, two look, three listen and four lift. One is to weigh the weight in your hand to see whether it is moderate; two is to see whether the glaze is mirror like and glossy, whether the color is soft, whether there is a feeling of jade, and whether the color of the picture is bright; three is to listen to whether the sound is as clear as gold stone if you tap with hard objects; four is to lift the porcelain to the light source to see its semi transparency and good bone china Transparency is high.

It should be reminded that due to the lead content in ceramic mugs, poor tableware will cause harm to human body in long-term use, so in addition to not greedy for cheap in the roadside or on the stall to buy. In the normal use process, there are also some points to pay attention to:

Before using the newly purchased tableware, it can be soaked in edible vinegar to dissolve most of the lead; in the process of using, do not use colored fine porcelain custom ceramic coffee mugs to contain acid food, so as to avoid chemical reaction; do not put the utensils with metal decorative lines and patterns in the microwave oven; when washing, add detergent with warm water, wipe with sponge or soft cloth, and then clean with clear water, Then use soft towel to wipe clean, do not use rough brush or cleaning cloth to brush, to avoid damaging the glaze of the tableware and producing scratches.
