Archaeoskin Gloves of Crafting

Taken all the way down to base materials, one Archaeoskin Gloves of Crafting is 2 crafting steps deep and needs 3 intermediates — Archaeornis Leather ×2, Mythrite Nugget ×1 and Rainbow Thread ×1 — which resolve to 6 distinct raw materials totalling 19 units, plus 15 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 958 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 9 Earth Crystal, 3 Fire Crystal, 2 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 51, Blacksmith to Lv 51 and Weaver to Lv 51 — so no single class can finish it unaided.

5 of the 6 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Rainbow Thread has the widest use: 116 recipes call for it, spanning five of the eight crafting classes.
