Blue Glazed Terracotta is the blue entry among the sixteen glazed terracotta colors, a family of vibrant, patterned solid blocks. A furnace converts one block of blue stained terracotta into one Blue Glazed Terracotta and awards 0.1 experience per smelt, while plain unstained terracotta cannot be glazed at all. Trading opens a second route: an expert-level mason villager sells one glazed terracotta for one emerald, carries twelve such trades in stock, and lists every color as a separate offer in Java Edition. A pickaxe mines Blue Glazed Terracotta, wooden tier included, while bare hands drop nothing. Blue Glazed Terracotta registers 1.4 hardness and 1.4 blast resistance.

Placement is where Blue Glazed Terracotta earns a build slot: the motif turns to match the direction the player faces while placing, and a 2×2 or larger field of same-color blocks in matching orientation merges into a single image. Most glazed terracotta textures also carry reflection symmetry along the corner-to-corner diagonal. One stack stores 64 blocks, sixteen complete 2×2 motifs for a large ornamental floor. Blue Glazed Terracotta suits builds that need a deep-blue accent with pattern instead of flat color.
