Why do you want to put kerosene in glass cutter?

Kerosene increases the surface tension of the glass, does not blast, and the cut surface is smooth. If you use a glass knife, it is not rubbed.glassOn the surface, you will see that there are glass flakes flying on both sides of the knife edge. We often say that it will be blown up, and it will not be rubbed with kerosene. The glass that is blown up is particularly prone to rotten. It can also be coated with gasoline and diesel, but because of the rapid evaporation, There is also an odor, so basically do not use these two.

Kerosene is a so-called ocean oil. Its molecular size is small, and it has good wettability with glass. When the glass knife is crossed, it acts as a "slipping" in the crack to make the fracture smooth.

Kerosene has a stagnant effect, which can prevent slippage between the glass knife and the glass. It can be used evenly and is not easy to cut.
