I wasted a lot of time trying to dissolve it by bringing the pH up to 14.5 (stupid meter didn't know any better).
I think I mentioned earlier in this thread or in Part I that pH meters just are not up to measuring above about pH 12.5 unless you have special electrodes and suitable standards. You should really take any pH meter reading above that level with a really big grain of salt unless you konw what you are doing and have the right equipment...
By the way, why not stop at pH 14?
