Each batch of products has a total metallicity (Σ☿) of 1 (☿) + 1 (♄) + 2 (♃) + 3 (♂) + 4 (♀) + 5 (☽) + 6 (☉) = 17, If we had the glyph of rejection:

Recall that ☿ = ♄ = 1 Σ☿
17Σ☿ / ((2 Σ☿) / (2 c)) = 17 c
17c * 6 = 102 c

We can solve the puzzle in at best 102 cycles, at a rate of 17
however we don't have the luxury that rejection would provide, so the min rate is slightly greater, how much greater is the question, as I still need to do the math.
