JackX, stop trying to look smart. He couldn't use pure sodium to represent sodium, and the closest thing on TPT is salt, which is a compound that has sodium in it. It's just the next best thing.
1 point: "Salt" is quite a vague term, as it refers to any molecule that is a mixture of metals and non-metals. The obvious example is Sodium Chloride, which is the most common. Interesting fact: Low Sodium salt is actually worse for your health as it is replaced with Potassium Chloride, which is more toxic.
btw glow can be colored by setting it CType like filt
