Hide Glue

Hide Glue

Definition

Hide Glue is a traditional adhesive made by boiling animal hides and connective tissue. It has been historically used in woodworking, instrument making, and canvas preparation for painting. Known for its strong initial tack, reversibility with heat and moisture, and long-standing presence in conservation practices, it remains relevant in fine art framing and restoration work.

Characteristics

• Composition: Protein-based adhesive derived from animal hides.
• Hygroscopic: Sensitive to moisture; can soften or swell when exposed to humidity.
• Reversibility: Can be softened or reactivated with heat and moisture, making it suitable for conservation and restoration.
• Drying Time: Sets relatively quickly at room temperature, depending on concentration and temperature.

Applications

• Traditional canvas preparation for oil painting.
• Fine woodworking and joinery, including musical instruments like violins.
• Art restoration where reversible adhesives are preferred.

Best Practices

• Store hide glue in a dry, cool environment to prevent premature spoilage.
• Use appropriate concentrations and warm the glue before application for optimal adhesion.
• Consider alternatives for modern framing applications if permanent adhesion is required, but hide glue remains valuable for restoration and conservation work.
