First of all I would like to thank you for all the time you have spent on your well written response.
I'm sure you understand my analogy wasn't meant to be extrapolated to incorporate all the aspects you have brought into it. And in may well be a very flawed analogy, but on the skin of it, there are some shared commonalities.
I thought I'd share what information I have because T-dub implied concern that alternatives were necessary because people were braking their glass because of it, which I find to be somewhat concerning (for reasons I have covered). I'm not here to discredit or belittle what T-dub has spent his time on, only question the implied (or not?) necessity.
While my assertion may seem out of line, I believe it is not. I assumed that proper cleaning techniques were being utilized. And in circumstances where they are, there is not an increased likelihood of breakage. My goal of getting to the bottom of the original "shake and break" comment was finally ascertained by your input, for which I am thankful. But if the correct technique is employed, then only lack of coordination is to blame, which is something that doesn't change with normal handling.
I suspected that people who pay many monies for pretty toys don't like seeing it wasted when they break them consistently, so I suggested an alternative.
BTW, there are other great ways to reduce the amount of mechanical input which is necessary for a person to input, like ultrasonic baths (really only practical for small pieces).
The thread was also not titled, "I'm tired of my glass breaking, what alternatives to materials/methods are there?"
I know the thread wasn't titled as such, I just wished to offer my advice.
If you find my opinion to be objectionable, please feel free to disregard it, as I do not wish that it take away from the intent of the thread's author, I only feel that specialized cleaners are not necessary given proper techniques.
A couple things for you T-dub, your self stated goal is to minimize necessary mechanical agitation. Other, less polar solvents might be what you are looking for. Also, please do not discount the danger of oxidizers, they have a great many drawbacks. (not to imply that you have done so, just a word of caution)
