On cheaper violins, some modes are so strong that suck all the air around them, and it's impossible to deliver a spectrum shift since there isn't any Say what?

Super related, at least insofar as potassium silicate and sodium silicate are functionally equivalent in this usage. Quote Link to comment Share on other sites More sharing options...

So you assume, but not according to what I found. But that was about 35 years ago, so I can't provide a source. Sacconi would have said water glass, much easier to find, if he has meant water glass.

I'm not trying to assume in this case, I'm speaking only about the chemicals and what their properties are. Most salts of potassium and sodium are very similar in function to one another (though not identical), the silicates are no exception by the numbers. I wouldn't put either on wood personally. Or rather, I have tried both: alone, in combination with other things, in various concentrations. None of these yielded what I would, personally anyway, consider acceptable results. If anyone uses it any likes it, that's fine of course. It's just not for me. Quote Link to comment Share on other sites More sharing options...

My apologies, though I wasn't intending to reference anyone's work, and certainly not yours. Quote Link to comment Share on other sites More sharing options...
