Sandustry materials

Sandustry materials are individual pixels with density, temperature, and reactions. This roster lists every official wiki material page that existed on 15 August 2026. Empty density cells are unpublished, not zero. Community names such as Slag sit in the alias column next to official Residue. Official store copy, the Hooded Horse wiki roster, and Steam patch notes are the only sources for numbers on this page. Community names stay in the alias column.

How to read the roster

Official infobox fields are Interactions, Density, Matter Type, Obtained From, Processed By, Byproducts, Burnable, Wettable, and Launchable. We keep that skeleton. Gold is the only solid with a published density of 300. Water is the only fluid with a published density of 100. Everything else waits for a first-party number.

Starter loop materials are Sand, Wet Sand, Water, Gold, and Residue. Mid-game adds Redsand, Amethelis, Voidbloom, and Fluxite. Heat is Lava, Scoria, Cinder, Fire. Cold is Ice, Snow, Steam when it condenses. Ancient and power pixels such as Auralite, Florinol, and Energy exist as named pages even when their machines are still redlinks.

Core refining pixels

Sand plus Water makes Wet Sand at 1+1=2. Wet Sand on a Shaker becomes Gold and Residue. Residue burns to Burnt Residue and then a Kinetic Press. That is the entire early economy. Dry Sand on a Shaker is a stall.

Wet Sand→Shaker→Gold + Residue

Redsand is denser than surface Sand and feeds the Fluxite botanical loop when mixed toward Voidbloom. Demo Hotfix 8 reduced rocket mining as a Redsand strategy. Use belts and filters, not explosives, once you live in red layers.

Name	Aliases	Category	Density	Obtained	Processed	Summary
Sand		surface	—	Surface dig, Dirt layers	Water contact	Starter granular solid. Mixes with Water into Wet Sand. Dry Sand on a Shaker produces no Gold.
Wet Sand		surface	150	Sand + Water	Shaker	Official density 150. Sand + Water makes Wet Sand at 1:2 (one water). Only this state belongs on a Shaker. Gold falls through; Residue stays on top.
Gold		product	300	Shaker on Wet Sand, Kinetic Press on Burnt Residue	Research spend	Heaviest printed pixel (density 300). Research currency only after it sits in a Collector. Can smelt to Liquid Gold and still count. Shaker chance about 1 in 4.
Residue	Slag	byproduct	50	Shaker	Fire, Lava, Kinetic Press after burn	Official density 50. Official name Residue (community: Slag). Every Shaker Wet Sand makes one Residue. Fire: each pixel has a 25 percent chance to become Burnt Residue, else it is consumed.
Burnt Residue	Burnt Slag	byproduct	—	Burned Residue	Kinetic Press	Residue after fire. Drop at least 25 blocks onto a Kinetic Press for 1 Gold + 1 Seed. Too little height and it just sits.
Water		fluid	100	Lakes, Melted Ice, Burned Snow	Sand wetting, Heat, Cold	Official density 100. Heats to Steam, freezes to Ice. Sand drinks limited reservoirs. Lumlings are the documented infinite refill. Pipes move it; lava cannot share those pipes.
Ice		fluid	—	Cold Water, Snow + Water	Heat, Flamethrower, Lava	Steam page physics: Ice melts when heated. Thick ice walls are a common vault obstacle.
Steam		fluid	—	Boiled Water	Cooling, Rain	Rises when water boils. Official copy says it can fall again as rain if it reaches the sky.
Snow		cold	—	Cold biomes	Fire, Water, Lava	Cryoblaster writes infinite Snow. Snow freezes Water, solidifies Lava, or can be steamed into rain.
Redsand	RedSand	deep	—	Deeper biomes	Amethelis mix, Filters	Denser sand variant used in Fluxite loops. Demo Hotfix 8 reduced rocket spam as a quarry method.
Redsoil		deep	—	Red biomes		Official wiki pixel. Treat as the packed/red-soil companion to Redsand until a full infobox is copied.
Fluxite		product	—	Natural veins, Flux Emanator	Inventory upgrades	Second currency. Official beginner page: unlocks upgrades for Grabber, Flamethrower, and Drones.
Amethelis		botanical	—	Flowers	Redsand mix, Drying	Petal resource from flowers. Mixed with Redsand toward Voidbloom. Also sits on the energy chain toward Florin.
Dry Amethelis		botanical	—	Dried Amethelis	Energy chain	Dried petal step on the official energy path: Amethelis → Dry Amethelis → Florin → Florinol.
Voidbloom		botanical	30	Amethelis + Redsand	Flux Emanator	Official density 30. Void Petals + Redsand. Feed the Flux Emanator 1:1 to grow Fluxite.
Void Husk		void	—	Void plants		Official void-plant leftover. Keep on the roster; do not invent a recipe.
Void Juice	Voidjuice	void	—	Void plants		Official liquid void product. Locator text on the official wiki mentions it.
Void Petal		void	—	Void plants		Official void botanical part.
Void Seed		void	—	Void plants	Planter Box	Official seed variant for void flora.
Seed		botanical	—	Plants, Kinetic Press spores	Water, Planter Box	Steam: watered seeds bloom into flowers that can be ignited for resources.
Wet Seed		botanical	—	Seed + Water	Growth	Wetted seed state before bloom.
Flower		botanical	—	Watered seeds	Fire, Harvest	Planter Box product. Official article: Moss stem + 4 Amethelis + 1 Gold. Destroy with weapons or Fire.
Moss		botanical	—	Damp surfaces		Official organic pixel. Treat as a fire-spread risk near flamethrower work.
Lava		heat	—	Deep heat, Remelted Scoria/Cinder	Cooling, Snow contact	Official heat fluid. Used to burn Residue and cut ice. Pipes and vents move it.
Scoria		heat	—	Lava + Snow or cooling	Further heat	Cooled lava rock used to relocate heat without an open lava lake.
Cinder		heat	—	Scoria chain	Remelt	Frozen lava. Official lava-move path: freeze Lava to Cinder, haul it, reignite with a Flamethrower.
Fire		heat	—	Flamethrower, Ignited organics		Spreads through organic tiles. Official tool path for Residue and flowers.
Dirt		terrain	—	Surface		Common terrain pixel on the official materials list.
Stone		terrain	—	Crust	Drill, Explosives	Hard crust pixel. Prefer tools over shovels once you leave sand.
Crackstone		terrain	—	Mid layers	Heavy tools	Official hard rock. Community guides ask how to break it; use heavy tools, not shakers.
Copper Ore		metal	—	Ore veins	Heat	Official ore. Smelting buildings on the official wiki are still partly redlinks, so do not invent a smelter recipe.
Copper		metal	—	Copper Ore	Heat	Refined copper pixel listed on the official wiki.
Liquid Copper		metal	—	Melted Copper	Molds	Molten copper. Copper Mold is still a redlink building.
Liquid Gold		metal	—	Melted Gold		Molten gold pixel. Do not assume it spends like solid Gold on the research desk.
Auralite		ancient	—	Ancient layers	Research spend	Ancient crystal currency mentioned beside Gold on the official research page.
Aurixite		ancient	—	Ancient layers		Official related crystal. No public recipe on 2026-08-15.

Phase-change pixels

Steam’s about text is the physics card: ice melts into water when heated; water turns to steam and rises if boiled; steam can return as rain. Snow can be burned for water. Snow plus water makes Ice. Snow plus lava makes Scoria and consumes the snow. Plan heat before it cooks a wetting tank or floods a vault with steam.

Indestructible pixels mark map bounds and some vault shells. Tools do not delete them. Treat that as a layout constraint, not a bug.

What we refuse to invent

Copper Ore, Liquid Copper, Prismite, Moonhop, Sunsand, and several void parts have official names and no public recipe. They stay on this table so the roster matches the official wiki floor. They do not get fake densities or invented smelter outputs.

How a player uses this table

Sort by category when you are shopping for a loop. Surface pixels feed the Shaker. Fluids feed the tank. Heat pixels feed the burn lane. Botanical pixels feed Fluxite. Ancient and power pixels are late. If a row has no density, do not invent a Filter setting. Split that belt by hand until someone publishes the number.

Compare piles against the roster, not a guessed chart.

Frequently asked questions

Why is Slag missing?

It is not missing. The official name is Residue. Slag is the community alias used on sandustry.wiki and older demo guides.

Why are so many densities blank?

Only Gold (300) and Water (100) have first-party numbers we could verify. Blank is more honest than a guessed chart.

Do I need every pixel to finish Early Access?

No. The published win condition is industrial expansion plus ancient vaults. Sand, Water, Gold, Residue, Redsand, Fluxite, and the botanical chain cover the documented currencies.
