To become coal the gel layer must be heated. This comes from rising geothermal heat trapped by the insulating effect of the thousands of feet of sediment that buried the peat swamp. When heated to 150 degrees Fahrenheit, the gel begins to change into coal. The higher the temperature and the longer the time the greater the heat value of the coal.
