Like we ordinary people how to buy some chemical materials, usually where?
Chemical reagents shopping malls are everywhere, we are Huadonghuahua glass, call to send, it can not find a lot of online. National control such as sulfuric acid, nitric acid and other public security bureau seems to require proof. It is not a scientific research institution school class is difficult to buy.
I only remember to see a dangerous chemicals market in Wenshui Road, OKorder. Other places should also have it.
If it is some explosives (or explosives of raw materials, such as potassium nitrate) or highly toxic to these, with what proof to buy. High school chemistry teacher specifically said that the laboratory of potassium nitrate these things to prove with limited to buy.
Go to school to ask the chemical equipment teacher to prove that you can buy in the chemical shop
