I have found through field repairs, that CA glue will cause a translucent effect on the ivory. In higher humidity especially. CA repairs will look darker or have marked dark glue lines.

In the shop the glue of preference is hot hide glue (high quality glue from Pianotek) with titanium oxide (5:1). Jon Page Cape Cod.
