Tip - Time required for max Oven Spring and Ear Formation
At this time I think that the time required to reach maximum oven spring and ear formation is dependent upon many variables. Such as oven heat, thermal mass in the oven, steam, flour types, and a host of other variables. But, in order to get a ball park idea of the time required, a time lapse video was produced and from that video images were extracted at 1 minute intervals.
The results of that test is below.
