QUARTZ PILLAR

Where granite, diorite and andesite only ever leave your inventory at the Mason, quartz pillar runs the opposite way: he sells it, 1 for 1 emerald, the vertical-grain block used to cap columns and pillars rather than something he wants off your hands.

A crafting grid turns 2 quartz block into 2 quartz pillar, so buying it from the Mason skips a step that otherwise starts back at raw nether quartz, smelted and pressed into blocks first.

A Mason at Master sells 1 quartz pillar for 1 emerald, a fixed price rather than a rolled one, so a second Mason at the same tier asks exactly the same.

Quartz Pillar sells for as little as 1 emerald, from the Mason at the Master tier, and nothing else on that list costs more. The price is fixed rather than rolled, so a second Mason will quote you exactly the same.

The Mason at its master tier asks 1 emerald for a quartz pillar. 8 of the 72 villagers that pay emeralds, emptied out:

a diamond against 30 flint for the same 1 emerald, 30 times the carrying, and the shortest wait is the Leatherworker at 37.5 real seconds of shelf, gathering not counted.

Reaching master takes 250 banked trading experience and every tier below it cleared first, level 5 of five, the far end of what a Mason can become. Nothing shortcuts that climb; a freshly employed villager is four promotions away from this shelf.

Once there, the slot holds 1 quartz pillar at a time, 12 uses before it locks, refilling on the same twice-a-day restock timer as every other offer he carries.

12 purchases close the slot, and it needs 2 real minutes back at the stonecutter before it opens again, at most twice inside one 20-real-minute Minecraft day.

Camped for both fills, one Mason hands over 24 quartz pillar for 24 emeralds a day, then sits full again waiting for the next visit, however long that takes.

Draining the slot costs 12 emeralds for 12 quartz pillar, the same rate whether bought in one visit or spread across several, so there is no reason to ration it.

Where the emeralds go: the same Mason buys clay balls for emeralds too, one way to fund this purchase without touching a separate income source.

Also on the Mason's list: quartz block, brick, stone, chiseled stone bricks, granite and andesite.

A quartz pillar is quartz blocks turned into a carved column, which means a Nether trip, a crafting step and then a second one. Buying it from a Mason skips all three, and that is where the price comes from rather than from the material.

Pillars can be laid on their side, and the grain follows the direction they are placed, so they double as beams and as trim. Nothing else in the white palette does that.

A quartz pillar is directional. Place it and the grain runs along the axis you placed it on, so a column and a beam are the same block laid two ways, and a wall of them can be made to read vertically or horizontally on purpose.

That is unusual for a decorative block. Most of the quartz family is uniform on every face, and the pillar is the one that rewards thinking about direction before you build.

A stonecutter makes them one for one from quartz blocks with no waste, and the same cutter gives the bricks and the slabs, so one trip's worth of quartz covers the whole set.
