Oddly Specific Glass ★★

Taken all the way down to base materials, one Oddly Specific Glass is 2 crafting steps deep and needs 1 intermediate — Refined Natron ×1 — which resolves to 3 distinct raw materials totalling 3 units, plus 21 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 426 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 14 Water Crystal and 7 Lightning Crystal.

Every step is Alchemist work, from a Lv 76 intermediate up to the Lv 80 finish, so one class covers the whole chain.

2 of the 3 raw materials come out of the ground, and one of them is time-gated: Ala Mhigan Salt Crystal (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Refined Natron has the widest use: 6 recipes call for it, spanning three of the eight crafting classes.
