Hide glue is available in various strengths, but as the strength of the glue increases, the amount of time you have to work with it shortens. Prepare only as much glue as you expect to use in a day or two.

Our granular hide glue is a very strong one (rated 260± Bloom strength) with a correspondingly short open time; it is good for uncomplicated assemblies where strength is of paramount importance.

Pearl hide glue, which also comes in dry form and is used the same way as granular, is not as strong (rated 150g Bloom strength) but takes longer to gel. With the longer working time, it is better for applications like veneering where you need time to fit, but where high strength is not required.

Hide Glue Characteristics:
  • Heat Resistance: low

  • Water Resistance: low

  • Solvent Resistance: moderate

  • Sandability: good
 
Hide Glue Applications:
  • Pot Life: all day

  • Open Assembly Time: 3 to 5 minutes

  • Clamp Time: 60 minutes

  • Joint Conditioning: 24 hours

  • Freeze-Thaw Cycles: stable

  • Wet Clean-Up: water
If you have never worked with hide glue, it is best to start with a small batch. A larger batch of glue may be made using the same proportion of glue to water. Put 3 tablespoons (45ml) of dry glue in a heat-resistant glass container, cover with 2 tablespoons (30ml) of cold water and let soak for several hours until the glue softens and becomes gelatinous. Place the container with the gelatinous glue in a bath of water in a spiral-wound electric pot, a waterjacketed pot or a double boiler. Heat to approximately 140°F (60°C) and maintain.

A properly prepared and heated batch of glue forms a steady thread as it drips from a brush back into the glue pot, much like honey on a honey dipper. If the glue drips from the brush in droplets, it is too thin. To thicken the glue, stir the glue while it is being heated until sufficient water has evaporated from the mixture. If the glue forms thick clumps on the brush, dilute it with hot water until the desired consistency is achieved.

Apply the glue with a stiff brush and join the pieces while the glue is still hot. As the glue cools, it will gel and lose its adhesive properties.

Note: The consistency of the glue may require modification if it is kept heated for considerable time or if it is reheated. Overheating the glue will spoil it, as will reheating it more than four times.

Dry granular hide and pearl glue can be safely stored for extended periods in airtight containers in a cool and dry place. The mixed glue can be stored for several days in a covered container in the refrigerator. The presence of mold or a strong smell indicates that the mixed glue has spoiled.
