-The LOI summarizes the components within a raw material that burn away or products of decomposition that are lost as gases during firing. Some companies separate the different components of weight lost during firing as C, H2O, SO3, etc. A formula weight of zero should be used in each oxide of this type so there is no impact on fired formula calculations.
-Note that if a material contains a volatile in its analysis that you would like to enter into the analysis and have it treated like an LOI, and if that item is not contained in the OXIDES database, you can manually key an 'L' in the status column of the analysis to force FORESIGHT to accept it as an LOI type material.
-A material's formula weight is equal to the sum of the weight of the oxides in its formula divided by 100-LOI divided by 100.
