Question

To blow glass, it must first be: heated, sanded, or frozen?

Answer 1

To blow glass, it must first be heated. Glass must be heated to a very high temperature in order to be shaped and formed. The glass is then shaped by blowing air into it through a pipe. Once the glass is shaped, it is cooled and can be used for a variety of purposes.

Answer 2

To blow glass, it must first be heated. Glassblowers use furnaces that reach temperatures over 2000 degrees Fahrenheit to melt glass into a molten state. Once the glass is melted, it can be shaped and molded using various tools and techniques. Sanding or cutting is a process that occurs after the glass has been cooled and hardened to achieve a desired texture or shape. Freezing glass, on the other hand, is not a common or applicable technique in glassblowing.
