The experience of making modified water glass
Now there is a method of making modified water glass, which is quite exquisite. During the experience, I would like to describe in detail.

At the beginning, the selection of materials is very important. The materials must be pure and good, and impurities should not enter, in order to ensure the quality of the finished product. Choose excellent silica sand and soda ash, the ratio of the two, and prepare according to the law, the difference of the millimeter, or the change of quality.

When making, the heat and duration should be carefully controlled. The material in the kettle should be boiled over a moderate fire, observe its color and state, and stir it at the right time to make the material uniform. If the fire is fierce, the material is easy to burn, and if the fire is small, it will not be completely melted. Insufficient time, incomplete reaction; too long, or damage its properties.

After that, the cooling process cannot be ignored. Slow cooling makes the quality stable, and sudden cooling may cause cracks, which affects the quality. Cold to moderate temperature, and then test, observe its concentration, viscosity and other indicators, if it does not match, adjust it according to the method.

Making modified water glass requires caution in all aspects. Only by doing it with care, following the ancient method and improving it, can it become a good product and be used in all things, with significant effect.
