how to store calcium granules?

Straight from CLEAPSS



Storage code: FW [Silver-grey metallic granules or
irregular-size/shape pieces]
• Calcium: A grey-white oxide layer may form on granules/pieces. Purchase small quantities (eg, 25g) and store in an air-tight container to minimise oxidation.
 
In a desiccator over say anhydrous calcium chloride if possible.

I find that even in the original air tight container it slowly oxidises to a white powder,
So I keep mine in it's sealed container in the desiccator with self indicating silica gel as the desiccant

Better than Calcium Chloride because you can see when it needs re-drying (orange when dry green when wet)

I agree that it is more useful, but I have lots of anhydrous calcium chloride.
