Shellfish are ones of sea product which use as food, and shell part as a waste. This experiment was done to utilize shell as main product in glass adhesive together whit Arabic gum and white part of chicken egg as sticky substances. The shell contended about 76,64 percent of CaCO3 which could repair adhesive working to increase shear strength and curing time. Adhesive were made by variation composition in gram number of shell powder and Arabic gum. The best composition was obtain on 68.45 percent of shell; 8.22 percent of Arabic gum; 1.42 percent of white part of chicken egg and 21.90 percent of water. This composition had 16,620.105 NM-2 of shear strength; 23.14 percent of volatility and 90.9583 pa.det or 909.5830 poise viscosity as optimal result at eleven days of curing time. In environment resistant test, shear strength decreased about 64.33 percent in acid; 17.96 percent in water; and 1.83 percent in base. Storage life test of adhesive was performed in closed box at temperature 27° C and fungi grew it in fourth week.
