Calcium chloride. A red-orange flame, not quite so bright as sodium, and not as yellow. Compare with the sodium pictures at the end of the
previous session. It shows up as a similar color, but much less bright. Worth it, I think, though it's not as spectacularly colored as strontium. Again, the camera doesn't do justice to the color - much more red.
Sasha again was able to get great detail within the flame, even though it was fairly bright.
