Thread: Liquids that don't react with citric acid

Hey chaps,
Excuse me if this is in the wrong section - I'm no science boffing!

I'm after binding some citric acid and baking soda together so when dry it forms a hard shape.

I now know oil (olive oil) when added does bind both items together without making them react.
I've just tried 'egg white' - it worked to a degree... but not great.


Any other items what does this?

mineral oil
