Why is there a "poisoning" incident of ultra-light clay? In the final analysis, clay has become "harmful" for two reasons: first, many private workshops have taken a fancy to the huge prospects of clay toys, but they have not monitored the production of clay products safely; Second, some "black-hearted" enterprises add inferior or even harmful chemical components in order to reduce production costs. Impure trace elements in low-cost industrial materials. Some small manufacturers will choose to use low-priced materials in order to reduce costs and increase profits. Pigment. Many clay pigments contain harmful substances, but large clay brands, with a view to long-term development, will not smash their own signs and generally use edible pigments. There are few high-quality brands that use imported pigments with better quality, which is why some clay is sold very cheaply, but some big brands are much more expensive. Preservatives and spices. The ultra-light main material PVA is one of the few materials that bacteria like very much. Non-toxic also means that it is very perishable. How much preservative to add and what kind of preservative to add depends on the manufacturer's conscience.
Some inferior clay will add a lot of preservatives, which will produce a so-called "pungent smell". However, parents should pay attention to the fact that some ultra-light clay that smells "fragrant" is even more unacceptable. "Fragrance" refers to adding a lot of essence to clay to cover up the smell of preservatives. Ultra-light clay is lighter and more plastic than plasticine. Because the works made of plasticine can't be preserved for a long time, there will be cracking and breakage, while ultra-light clay can be preserved for a long time after drying and molding, but it is also afraid of sharp tools and humid environment. Secondly, the color of ultra-light clay is very rich now. Most importantly, the works made of ultra-light clay do not need baking, and can be dried directly and naturally without cracks. It is an ideal manual modeling material.
Many parents are worried about whether ultra-light clay is harmful to children's health. In this regard, parents can rest assured that the ultra-light clay with good quality is non-toxic and harmless. The inferior soil contains heavy metals such as boron and arsenic, which is very toxic, and children will be poisoned if they eat it by mistake. If the soil you bought has a pungent smell, the skin of the extruded soil is red, swollen or itchy, and you have a headache when playing with the soil, please throw it away quickly. This judgment method varies according to the different purchase methods. Under normal circumstances, if they are bought in a physical store, parents can smell whether there is a strong smell or a pungent smell. If there is, don't buy it; You can feel it. Better quality, no fading, no sticky hands; Finally, you need to check the packaging of toys; Check whether there is a national security inspection mark. The higher the inspection level, the better the product quality. It is best to buy an internationally certified brand. As far as the inspection standard of ultra-light clay is concerned, the safety level of products certified by the European Union is higher.
