Enter the formula and formula weight directly into the Insight MDT dialog (since it records materials as formulas).
Enter the analysis into an Insight recipe and enter the LOI using Override Calculated LOI (in the Calc menu). It will calculate the formula.
MLPT - Melting Point (MP) 3100F

F-75 sand is a popular material used in modelling clay bodies to impart drying and firing properties. It is much cleaner than brick grogs.
