Direct answer

Sandustry scoria never occurs naturally: it is Lava frozen by Snow. It has 10 HP, breaks to any regular digging tool, and yields portable Cinder.

Scoria never occurs naturally - it is frozen Lava, formed when Snow (usually from a Cryoblaster) hits a lava pool. It is a tough block, harder than Dirt but breakable by any regular digging tool, and digging it yields Cinder. That two-step freeze-and-dig is the early-to-mid game answer to lava logistics, since the resulting Cinder can be carried anywhere and melted back.

How to get Scoria

Only one method produces Scoria: freeze lava with snow. Because nothing else feeds it, throughput here caps everything built on top of it.
