Potassium.

Does anyone have any ideal where I can source Potassium Silicate, I have drawn a blank so far, even Silicone Dioxide I believe will work, I have found a company on Alibaba.com but the shipping charge is absolutely ridiculous. It’s not the end of the world if I can’t find it,but a definite plus if I can.

Look for a chemical supply house - most big cities in Thailand have them to supply the university laboratories. I know the location of the one in Chiang Mai, if that is where you are.
