The average house fire burns at a temperature of about 1,100 degrees Fahrenheit, which isnât hot enough to destroy most metals and earthly-made substances.And if an item is well-placed and small in size, its chances of survival increase drastically.old melts at a much cooler temperature â about 2,000 degrees Fahrenheit â but thatâs enough to survive most house fires. Platinum jewelry is the priciest, so itâs a good thing that the metalâs melting point is just higher than 3,200 degrees Fahrenheit. Sapphire and Ruby also possess extremely high melting points.
1200 deg. for 20 minutes to 1700 deg. for 1 hour. Aside from the higher deg at a longer time being better, what is the. temperature of a normal house fire.
