Temperatures inside this giant oven will reach 2,100 degrees Fahrenheit. Large blocks of glass inside the oven will melt as the whole oven spins around at a rate of five times per second, creating a curved and smooth telescope mirror.

The pieces of glass that technicians are arranging inside the rotating oven will melt down into the curved surface of the telescope mirror. Each piece of glass is hand-inspected.
