What is the primary advantage of animal glue in woodworking?

Its reversibility. Joints bonded with animal glue can be disassembled later using heat and steam, making it essential for antique restoration.

How is animal glue graded?

It is generally graded by its jelly strength (Bloom value) and viscosity, which dictate the open time and structural strength of the bond.

Is animal glue water-resistant?

No, animal glue is highly susceptible to moisture and should only be used for interior woodworking and joinery applications.

This standard specifies the requirements, sampling, and testing methods for animal glue used in general woodworking and joinery. While largely superseded by synthetic adhesives in modern construction, this code remains relevant for specialized applications like antique furniture restoration, instrument making, and traditional crafts.

Practical Notes

Animal glue is reversible using heat and moisture, which is a highly desirable property in antique restoration but unsuitable for exterior or high-moisture environments.

The glue must be prepared in a temperature-controlled glue pot to prevent degrading the proteins through overheating.
