Description
Blue cobalt glass is a special kind of fire-seeing glass, mainly used in chemical laboratories for fire-seeing potassium flame reactions. It is also used in many industrial applications (e.g. cement plants, steel plants, industrial kilns).
Features
- Size: 5.50x5.50x0.50cm/2.16x2.16x0.20 inches.
- Material: Glass.
- Blue cobalt glass is a viewing glass that mainly serves as a filter and protector.
- The production process for blue cobalt glass is special. It is a special glass made by adding "cobalt blue" (the main component is cobalt meta-aluminate: Co(AlO2)2) during the production process.
- The addition of cobalt blue gives the glass a special blue colour, hence the name blue cobalt glass.
- When observing the flame colour reaction of potassium, it is necessary to look through the blue cobalt glass because the potassium compound is impure and often mixed with some impurities, such as sodium (which cannot be easily separated).
- It is generally used in laboratories or industrial cement production, steel plants and other high-temperature furnace mouths.
