Hello all, Some bridge makers claim their bridges have been treated (whilst untreated bridges are also available). Could you tell me what is the purpose of treatment and what chemicals do they use? Do they treat the wood just because of darker look, or because of sound quality? Thanks!

Hi all! I did an experiment yesterday by putting a pH indicating dye on a strip of maple. I let that dry, and then applied 5% sodium nitrite solution to it, and placed it in the light box. To my surprise, only after a few minutes of light exposure the dye changed from orange to a cool red, indicating the presence of a base. I had always thought that nitrite reaction produces nitric acid, so, I’m very confused as to why this test indicates as alkaline. Anyone have a possible explanation? Also, I’m wondering if this is a good approach to create a pH neutral treatment? I’m not a chemist, but I imagine one could find the proper salts to add, to make sure the dye does not change color through the process.

Today the intern of my shop showed me the ribs of his newest viola. They had a nice yellowish brown color and he told me that he made it with soaking them in a Borax solution for 24 hours. He told me that he read somewhere that this treatment stabilizes the wood and makes it fire proof. I had heard about this for making wood fire proof but can it stabilize the wood? Has anyone here experience with such a treatment and what were the results?
