Claim 29:
30. The method of claim 1, wherein the burned organic matter comprises rice hull ash, wherein the pressure-cooked reaction mixture or the preliminary sodium silicate solution travels through a heat exchanger to cool to a lower temperature, wherein the clean water flows through the heat exchanger before the step of contacting, wherein the clean water is below the rinse temperature before the clean water flows through the heat exchanger, wherein the method has the capability to consume a minimum of 1,142 kilograms of rice hull ash per hour, wherein separating the preliminary sodium silicate solution employs activated carbon, wherein the target sodium silicate solution is heated to evaporate water, and wherein the evaporated water is employed in the step of contacting the ash.
