BMS Gypsum Type IV Golden Brown is a premium extra-hard dental die stone specifically formulated for high-precision fixed prosthodontics. Manufactured by BMS Dental, this Type IV die stone is indicated for crowns and bridges, inlays, onlays, and skeletal framework work where maximum surface hardness and dimensional accuracy are essential for successful restorations .
The golden brown die stone achieves an exceptional compressive strength of 950kg/cm², providing the abrasion resistance necessary for multiple wax-ups without damaging the die surface . Setting expansion is precisely controlled at only 0.1%, ensuring that dies reproduce the master impression with clinically acceptable dimensional accuracy for high-fidelity restorations .
The optimized water-to-powder ratio of 20-22ml per 100g produces a workable mix with smooth flow characteristics that capture fine marginal details without air entrapment . For consistent results, BMS recommends vacuum mixing for 4 minutes, with manual spatulation requiring 5 minutes. Initial set occurs at approximately 5 minutes, with final set at 10 minutes under standard laboratory conditions .
The golden brown color provides excellent contrast when working with wax, resin, and composite materials, reducing technician eye strain during die trimming, margin marking, and wax pattern fabrication. Available in a 25kg bulk package, this Type IV stone is ideal for high-volume dental laboratories and practices seeking consistent, reliable die material for precision restorative dentistry.
