Not quite, Anon. The melting point of common sand is about 1700 degrees Celsius. A conventional, blowtorch-design flamethrower can only reach about 1000 degrees Celsius. With the fireball, you might get around 1500-2000 degrees Celsius, but it's instantaneous, which would reduce the yield of the glass.

And besides, why use Fireball when you could use Leomund's Tiny Hut and stay there for eight hours!
