Why is the enamel glass reactor blue?

The enamel glass reactor is one of the commonly used equipment in laboratories,with a blue surface.This blue color is not the color of the enamel material itself,but is formed by adding iron ions.
Iron ions are added to the raw materials of the glass lined reactor,and after high-temperature heating,the iron ions are reduced to iron ions.This chemical reaction causes the surface of the glass lined reactor to appear blue.This type of blue is formed through diffraction of light,and the depth of blue varies at different angles.
1、The advantages of blue in glass lined reactors
1.Beautiful appearance
The blue color of the enamel glass reactor is very beautiful and can improve the overall aesthetics of the laboratory.
2.Protective function
The blue color on the surface of the enamel glass reactor is not only a beautiful decoration,but also serves a protective function.The blue color can reflect some ultraviolet and visible light,reducing the internal light exposure of the reactor,thereby reducing the light and heat reactions and protecting the reactants inside the reactor.
3.Durable
The formation of blue color on the surface of the enamel reactor is achieved through high-temperature treatment,which allows the blue pigment on the surface of the enamel kettle to firmly adhere to the surface and not easily fall off,thereby increasing the durability of the enamel reactor.
2、Other advantages of glass lined reactors
In addition to the advantages of blue mentioned above,glass lined reactors also have the following advantages:
1.High chemical stability
Glass lined reactors have high chemical stability and can withstand the erosion of most chemicals without generating any chemical reactions.
2.Good thermal stability
Glass lined reactors can withstand high temperatures without experiencing explosions or ruptures in a short period of time,and can maintain their original shape and performance.
3.Easy to clean
The surface of the glass lined reactor is smooth,easy to clean,and does not contain any residual chemicals,ensuring the accuracy of the experiment
The formation of blue color on the surface of the enamel reactor is achieved through the addition of iron ions and high-temperature treatment.This blue color is not only beautiful,but also has a protective effect and durability,thereby improving the overall effectiveness of the laboratory.In addition,glass lined reactors have the advantages of high chemical stability,good thermal stability,and easy cleaning,making them an indispensable equipment in laboratories.
