Heater

The next, and penultimate (second-to-last), Advancement for Age 0 progression is the "Ace of Melter Base" Advancement, which has you making a Heater from the Tinkers' Complement mod. There are two options for the Heater: the Seared Heater or the Porcelain Heater.

- The Seared Heater requires six Seared Bricks (note that it is Seared Bricks, not Seared Brick), which are made using 24 of the Seared Brick item; one Stone Grill; and two Clay Barrel Extensions. The Seared Brick item is made by cooking Grout in a Clay Kiln, and Grout is acquired by placing sand, gravel, and clay in a mill stone, simultaneously.

- The Porcelain Heater requires six of the Porcelain Brick item; one Stone Grill; and two Clay Barrel Extensions. The Porcelain Brick item is made by cooking Unfired Porcelain in the Clay Kiln, and Unfired Porcelain is made by placing flint, clay, and white dye powder (e.g., not just bonemeal) in a mill stone. Make sure the items are placed in the mill stone in the order indicated in JEI, or it will not work. White dye powder is created by grinding white flowers or bonemeal in a grindstone of your choice.

The Clay Barrel Extension is created by cooking an Unfired Clay Barrel Extension, which is made with six clay and can be found in JEI, in a clay kiln. The stone grill recipe is easily found in JEI, and you can cook cobblestone in a clay kiln to get stone.

Once you have all of these items, simply assemble them on a crafting table in the order indicated in JEI, and you will complete the achievement. Congrats!
