The science behind adding steam while baking - From Food Science Tips

Ever wonder how professional bakers get those beautifully domed loaves a bread with glossy brown crusts? The secret - at least one of them - is steam...

In the first few minutes of baking, loaves of bread will rise rapidly as the gases trapped inside expand and the yeast has a final burst of activity (this is called " ovenspring"). Steaming within this time helps keep the crust soft. This allows the bread to continue expanding freely.

The steam that has settled on the surface of the bread also dissolves sugars in the dough. As the bread stops expanding and the steam begins to evaporate, the sugars are  left behind to caramelize and create a glossy crust.

Steaming is really only useful during the first 5-10 minutes of baking while the yeast is still active and the internal structure hasn't set. After this time, the crust needs its own time to set and dry out.
