Separating calcium and potassium chloride salts

[GadgetBoy]

So, I'm an electronics technician, so my knowledge of chemistry is limited to some rudimentary knowledge regarding battery chemistry and electrolytic capacitors.

 

So, I need some calcium chloride to raise the density of water to do a glitter lamp, but it's expensive to order online. I can, however, get desiccant at the local hardware store, which contains a mix of potassium and calcium chloride. Is there a simple way I can separate the two?

You might not need to do the separation as such.

Keep adding the mixture of chlorides to water until you get a solution which is dense enough. The potassium chloride won't do much harm .

You may need to filter the solution or let it settle to get rid of suspended particles.
