Collagen Glue Set
The Collagen Glue Set contain four different collagen glues. The set is especially useful for exploring the function, strength and behavior of different glues in grounds and painting mediums. Animal glues vary in strength, but rabbit skin glue usually offers the highest strength, viscosity and elasticity. True rabbit skin glue tends to gel at lower temperatures, making it easier to use in gesso applications. Otherwise, glue made from bovine collagen are comparable.
The set includes four 4 vol oz. jars each of:
|This is a high grade glue made in the U.S. It is a fine mesh granular glue that is easy to dissolve in water. The high-quality grade means that it is light in color and most strong glue available. This makes it ideal for use in gesso and as a medium for distemper painting.|
|High-grade glue made in the U.S. of pure bovine hides. The glue is manufactured from the protein collagen found in skin, connective tissue and bones of animals. It is a 40-mesh (U.S. Standard Sieve) granular protein glue that is easy to dissolve in water. Its lower bloom value (lower than Rabbit Skin Glue) gives it a longer setting time, making it ideal for use in gesso and for sizes.|
|This is a technical grade of gelatin made in the U.S. It is a fine mesh granular gelatin that is easy to dissolve in water. The technical grade means that it is the lightest in color and most translucsent grade available. This makes it ideal for use in gilding. Gelatin is preferred by many professional gilders over hide glue, because it can take a super burnish easier than hide glue when mixed with gilder's clay or gesso.|
|High-grade bone glue imported from Italy made of pure bovine and porcine bone. Bone glue pearls are easy to dissolve in water. Bone glue is a harder and less flexible than hide or rabbit skin glue, and stronger than technical gelatin. Animal glues vary in strength, but bone glue usually offers increased hardness over hide glues and longer open time.|
