I bought my first TF-100 last spring. A couple of weeks ago I ordered refills. My old R-0870 powder has darkened. The new powder is lighter. Is my old powder still good to use until gone or should I throw it away and go with the lighter powder (or combine them into 1)?

If it still turns the water pink it's still good. Use it up. And if you're ever in doubt, repeat the test with the new stuff.
Just pulled out my backup .25lb container of R-0870, only to find that the snap top had come loose over winter, and while still ash gray in color, the entire contents of it had solidified into a solid brick due to the exposure to moisture. Is it still usable at this point, or once it has completely solidified is it a lost cause?

You can break it up and see if it is good. Typically still good until it turns really dark in color.
