With etching, the freq vs time is variable, depending on temperature & how often the solution has been used before. I think one has to approach it as an experiment vs a controlled process.

Ken, any numbers with that, to give me a ballpark idea of frequency change and time ? Thanks for mentioning 'Whink'. I did not know about that. I have a bunch of 69xx kHz rocks which are likely candidates. -Hue Miller
