Overview Teton Foundry Supply™ prepackaged Hydrocal®* White is a high-performance gypsum-based casting material that reaches an impressive 6000 psi strength when fully cured. Use it where fine-detail reproduction is desired along with chip-resistance. Supported Applications -Solid/Hollow casting of various decorative objects -Low-use foundry patterns and other similar tooling Uses -Modeling (scenery) and professional art applications -This product is NOT compatbile with molten metal (do not use as a mold for molten metal) -This product is NOT recommended for outdoor or wet area use. -DO NOT use this product to make castings of humans or live animals (severe burns possible). Directions -Mix 40 to 41 parts water per 100 parts Hydrocal (by weight) -Always add plaster to water, sift or break apart lumps in plaster before adding, and mix well. -Sets approximately 25-35 minutes after mixing -Clean tools prior to product setting or it may be hard to remove product from tools.
