Nerve Glue by Ardec

Briançon Nerve Glue is an animal adhesive sold in grain which is made from cattle nerves. This glue is reversible when heated, allowing glued parts to be strengthened or removed.

Nerve glue’s stringy structure adapts well to varying degrees of wood moisture, while also offering a robust yet flexible adhesion. This glue is used for paintings restoration as well as for the bonding of delicate fabrics, leather, textiles, and for other specialized applications. It is a biodegradable glue which will not stain wood or textiles.

Nerve glue is often used in a mixture, particularly with bone glue, for its hardness: ⅔ of bone glue to ⅓ nerve glue. Some artisans will have more elaborate recipes based on their specific needs.

How to use

Preparation:

Use clean containers;
For a strong adhesion, mix one part of glue with one part of water (i.e. 100g glue for 100ml water). For surface treatment, mix one part of glue for 3 parts of water;
Pour the nerve glue in the pre-measured cold water;
Let the mix swell for 1-2 hours. Water must be absorbed;
Heat in a bain marie (double boiler) without going over 60°C. Glue that has been brought to a boil will lose all its properties;
The prepared mix can be kept for no more than 24 hours.
