For most building purposes, ordinary mud bricks suffice. However, certain structures -- generally buildings that use great heat, such as forges -- require more durable kiln-fired bricks. To make these, silt and sand are formed into wet firebricks, which are then fired in a kiln to produce finished firebricks.
Made in a kiln
Cost to produce (6 firebricks): 6 wet firebricks, 8 wood Time to produce: 2 minutes
Made in a true kiln
cost to produce (12 firebricks): 12 wet firebricks, 6 wood Time to produce: ~1 minute
The construction of a true kiln takes 48 firebricks, so to bootstrap you need to use a box kiln first.
