Construction

Decorative slate plates with an engraved digit, a letter or the fragment of a letter. The plaque of a previous record in abandoned labs and the number plaque in the houses of work towns are made of them. No recipe.

The mod's building concrete. Cement burned from any slag, mixed with sand, gravel and water, makes fresh concrete; placed in the world, it sets within one game day into strong industrial concrete. Comes with slabs and stairs.

Four tempered iron building blocks modelled on vanilla ones — bars, a ladder, a trapdoor and a chain. They behave like vanilla and look like the mod's steel.

Foundations in three tiers, tempered iron scaffolding, a concrete and a plate rail beam, a reinforced plate block with slabs and stairs, and a hazard stripe block: the blocks the quarry will later be built from, and solid industrial decor until then.

Clear glass in a tempered iron steel frame — it breaks like stone and holds against a creeper or TNT blast. A building block and an ingredient for later recipes.
