[China Glass Network] Glass exists in every corner of our life, common things, glass on the building, decorative glass in the family, and even the cups we drink are mostly made of glass. The teacher used it in the classroom. The utensils are also made of glass. But I don't know if you noticed that there are many patterns on many glasses. There are also many scales on the glass instruments that the teacher uses to experiment. How do these patterns and scales are "engraved"?
Some people may say that this is difficult. Just look for something that is harder than glass and you can pattern it on it. The hardness of the metal is higher than that of the glass. We can find a metal knife to see if it can be used to engrave the pattern on the glass. As long as people who have tried this way will know that it is impossible to pattern on the glass.
So, how do people engrave these patterns? This has to say a crucial chemical, hydrofluoric acid is a chemical that can strongly corrode glass. People use the characteristics of hydrofluoric acid, apply a layer of paraffin wax on the glass, and then use a knife to cut the wax layer into a pattern and apply hydrofluoric acid. It only takes a while to wash away the residual hydrofluoric acid and scrape off the wax layer. A beautiful pattern appears on the glass. Therefore, the cuts on the glass that we usually see, the scales on the glass instruments are all "carved" with hydrofluoric acid.
