Brewer Pottery Sherd is an archaeological item obtained by brushing the suspicious sand blocks that generate inside desert wells — small sandstone structures found in desert biomes at roughly 1 in 1000 chunks in Java Edition (twice as common in Bedrock). Each desert well contains two suspicious sand blocks beneath its water, and every block yields exactly one item: the Brewer Pottery Sherd or the Arms Up sherd at 25% each, or a brick, emerald, stick, or suspicious stew at 12.5% each. The motif depicts a potion — the bottled product of alchemy — hinting that the ancient dwellers of the desert practiced brewing. Placing four pottery sherds or bricks in a 2×2 crafting grid — in any combination — creates a decorated pot with one motif per face, and the sherd's slot position decides which face carries the potion pattern. Breaking the finished pot by hand or with Silk Touch returns it intact; any other tool shatters it back into the four sherds. The potion motif suits alchemy labs, witch huts, and market stalls, pairing naturally with brewing stands, cauldrons, and ingredient storage.
