How we Get First Oven

Just as the Egyptians brought the prehistoric era to an end in about 3000 B. C. E, they appear to have produced the first closed oven . It was invented as a way to satisfy the demand for better bread . Flatbread had been around for approximately 5000 years, but Egyptians ovens enabled the bakers to produce bread with yeast, bread was no longer flat, it was rising.
   A traditional Oven is one of the simplest inventions, it traps heat within its walls in order to cook the food placed within. However, when considering the timing of the invention of the ovens .  
It is necessary to consider the agricultural advances that resulted in the need for it. After the last ice age around 10000 years ago, the land began to warm up from its frostbitten slumber and gradually provide its inhabitants with grain and other foods from the plant species that had been hibernating beneath the ice. Our predecessors may have been a little slow in responding to these new sources of nutrition but as demonstrated by the Egyptian bakers, they eventually got  there.                                                                        Open tandoor ( cylindrical clay brick) ovens have been found in Mohenjo-Daro, the indus valley city settlement also dating from 3000 B.C. E . However, it was the ancient Greeks who developed front loaded and portable ovens, and used them to turn bread making into a profitable venture.
