As you can see in diagram 2,
it is very important to take the temperature into consideration,
as the breaking time depends on it. At a temperature from 10º to 30º
we can reach the results in 10 hours (green line); however at a
temperature from 5º to 20º (blue line) the results are slower. But
they are still much slower from 0º to 5º (black line), where the
results are obtained after 50 hours.
