Sandstone

Sandstone is an item used in Masonry in Survival 303.

Overview
Sandstone is an uncommon item which can be crafted or foraged. It is found naturally on Desert island and Stonewall island. All islands have the materials needed to create sandstone in infinite quantities. It can be used to level up the masonry skill, though it is not as effective as using small stones.

Trivia

 * Quarries can "mine" sandstone out of Desert Island's Sandstone Mountain.
