Opening the glue actually means that your violin has activated its self-protection mechanism, don't panic. Be sure to loosen the strings first, as the body of the piano already has an opening to release pressure and can withstand less tension than usual. If the strings are not loosened, it may cause deformation or even rupture of the body. After completing the above steps, you can send the violin to a professional violin repairman for repair.

Common glue opening situations:

The most common location for glue opening is the fingerboard. Slight glue opening may result in gaps between the fingerboard and the neck of the instrument, while more severe cases may cause the fingerboard to fall off as a whole. The second most likely location for adhesive opening is at the junction of the face or back panel and side panel near the chin rest. Due to its proximity to the human body and high humidity, it is also a common location for adhesive opening.

Possible symptoms of glue opening:

When we produce unknown noise during playing, after excluding common factors such as loose accessories, it may also be caused by glue peeling. We often use the method of lightly tapping the edge of the junction between the panel and the side panel to listen for whether the sound changes from solid to loose, and even like two pieces of wood hitting each other, there may be glue cracking. The same method is also used to detect the back panel.
