About the Glass. The most usual and natural way of turning Sand into Glass, happens with Lightningbolts, and melts at about 3000 F. Let's say Ace's rather normal fire is about the temperature of a candle flame, i.e., 1832 F. Other usual fires, like a blowtorch can get up to 2372 F, and a bunsen burner is 2912 F. So, usual fire just can't cut it.
