For years, glass vitrification furnaces have used refractory ceramic blocks as their liner material. The understanding of how these materials will corrode over time is of utmost importance, as this will directly influence refractory service life and cost. Lab-scale tests varying temperature, time, and glass composition have been studied to better understand the driving forces affecting the corrosion rates of refractory ceramic materials. Critical to these tests is the evaluation of material loss via a physical measurement, which is sensitive to coupon preparation and physical characteristics of the corroded coupon. In this work, a fusion cast refractory (Monofrax<sup>®</sup> K3) was tested against simulated Hanford glasses using ASTM C621; a static test method used to compare isothermal corrosion resistance of various refractories. A method to remove the remaining glass from the corroded coupon using hydrofluoric acid is presented that facilitates more accurate measurements while simultaneously accelerating throughput of sample analysis.
