This morning I had a dream. One had a drawing of a blue plane with glass cover on top curved. For a long time I have wondered about glass.. In California Glass windows on a house is not built for heavy wind storms. But here near Chicago we have storm widows. All glass is obviously not all the same. And it would seem the glass windows on planes and jets need to be able to handle a lot of air pressure. Almost as if the glass is made of metal. . I’m trying to learn basics that I can build off of here. Some of these topics can leap over my head. So I figured if I start my own topics I can learn a bit at a time. My first question is.. Is Glass made of sand? Can glass be formed by anything else? How do you take sand or rock or whatever to make it into glass? How do they ad tint or color to glass? How do they make different kinds of glass? . Lastly is the mirror part of the glass family? Is a mirror made the same way as glass? . Remember keep it simple for now until I can understand and build off this. To those who answer I will respond in comments and most likely more questions. I probably could find stuff online to read. That’s kind of the boring way. If everyone reads everything online, there is no conversation. I will guarantee this though. At the other forum I know they won’t answer stuff like this. Everything is more surface talk. This is why I joined a forum like this to those who take time to look, observe, wonder, question, study, answer and so on. But don’t forget on this topic a little Windex is needed or thus then you wont be able to see the trees on the outdoors. And when you take your next sip of Kool aid we will know more about this glass. Any links included however will be helpful also.
