Lapis Dust is a non-metallic dust produced by grinding lapis lazuli ore in the Macerator, Ala Industrial's LV-tier crushing machine. One block of lapis ore or deepslate lapis ore macerates into six Lapis Dust at a cost of 300 EU, while a single lapis lazuli gem grinds down into one dust. Unlike the metallic dusts used for ore doubling into ingots, Lapis Dust cannot be smelted — it exists as a pigment and chemical reagent for a narrow set of tech recipes, so it is worth grinding only what a specific crafting step actually needs.

The main sink for Lapis Dust is the Electric Hoe Diamond Tip upgrade, which spends one dust alongside diamond dust and a cupronickel ingot in a shaped crafting grid. Surplus dust has two outlets: the Compressor turns one dust back into one lapis lazuli for 260 EU, and Ala Industrial's Industrialist villager (tier 2) buys ten Lapis Dust for one emerald across twelve trades. Because lapis itself is renewable through villager trading and the Macerator runs on EU, Lapis Dust is a fully renewable processed material for Minecraft 26.2 on Fabric or NeoForge.
