Compressive creep testing of ten commercially available mullite refractories was performed at C and at static stresses between 0.2-0.6 MPa. These refractories were examined because they are used in borosilicate glass furnace crowns and superstructures along with in sidewall applications. Additionally despite their high cost ( approx 500/ft sup 3 ) they are cheaper than other
