Jim,

I think you misunderstood my original question. Tim's answer makes sense to me (though he left out the actual answer... see below).

I asked how much of the Sun was primordial (i.e. H and He from the Big Bang) and how much was produced in first or subsequent generation stars. Tim's answer was that we can't tell material that was produced in first-generation stars from that produced in subsequent generations -- not that we can't tell primordial material from star-cooked stuff.

One website states that the Sun is 90 % hydrogen, 9 % helium, and 1 % heavier elements. So I conclude the Sun is 90 % primordial, 9 % indeterminate, and 1 % post-BB.
