Brush

A brush is a tool used in archaeology to excavate suspicious sand and suspicious gravel for different items. Brushes also can be used on armadillos to get armadillo scutes.

Using the brush on any block (apart from suspicious blocks) displays a brushing animation, slowing down the player and creating breaking particles, but not actually damaging the block or brush.

When continuously brushing suspicious sand or suspicious gravel, an item dependent on the structure's loot table slowly emerges from it until it drops out, and the block turns into regular sand or regular gravel, depleting 1 durability point on the brush. It takes 96 game ticks (4.8 seconds) to brush a single suspicious block.
