Colossal Furnace 1.2.1

Minecraft 1.21.1, NeoForge. Needs Jumbo Furnace. XP Works, JEI and EMI are optional.

Coming from the older file on this page ("Colossal Furnace 1.0.0 release", colossalfurnace-0.2.1-m6.jar)? This update has everything below. Your worlds open fine: built furnaces, everything in them and your upgrades' growth are kept. A world saved with this version can't go back to the old file, so back it up first.

1.2.1: JEI fix

• JEI now lists the near-grown Tier 2 Upgrade, Unfinished Tier 4 and Unfinished Tier 5 from the creative tab (it used to hide them as duplicates). Recipes and info pages still show for an upgrade at any growth.

1.2.0: Liquid Experience tank (with XP Works, optional)

• With XP Works installed, the furnace has a built-in Liquid Experience tank. Smelting XP flows into it (20 mB per XP point).
• Pipes are the only way out: connect any fluid pipe to any side of the furnace to pull the XP out.
• Tank size by tier: Tier 1 250 buckets, Tier 2 500, Tier 3 1,000, Tier 4 2,000, Tier 5 4,000, Tier 20 20,000 (1,000,000 XP points). Configurable (server config, section xp_tank).
• When the tank is full, smelting keeps going and the extra XP is stored the old way (you get it when you take the items out).
• If the tier drops and the tank holds more than the new size, nothing is lost: it just doesn't fill until it's below the size again.
• Breaking the furnace releases the tank's XP as XP orbs.
• A Liquid XP gauge in the furnace screen (hover it for the amount).
• Without XP Works nothing changes.

1.1.1: bug fix

• Fixed a Tier 20 furnace losing items and failing to save after a bonus upgrade was taken out while a big batch was cooking.

1.1.0: Tier 20

• With a Tier 5 Upgrade in the Upgrade slot, four bonus slots open under the Heart: Tier 2, Tier 3, Tier 4, Tier 5. Put one finished upgrade of each in them and the furnace becomes Tier 20 (1 + 5 + 5 + 4 + 3 + 2 = 20).
• Tier 20 has 5x the inventory: 135 input, 90 fuel and 135 output slots. 8,640 items at once, 2 s cook time, 64 items per coal. Overheat at Tier 20 = all 90 fuel slots stocked.
• The input, fuel and output grids scroll (mouse wheel or the scroll bars). The screen is the same size.
• The Tier 5 Upgrade is locked in while any bonus slot is filled.
• Take a bonus upgrade out and the extra slots freeze: their items are kept (not cooked, not reachable by hoppers) until you put it back. Breaking the furnace still drops everything.
• New Tier 20 frame colour, a server config section (tiers.tier20) and JEI/EMI info text.
• Fixed a lag spike when a big furnace started a new batch (a full Tier 5 batch froze the server for about 0.7 s; now under 1 ms).
• Fixed items being lost on save: if an enchanted item was cooking, everything cooking at that moment vanished when the world was saved and reloaded.
• Busy furnaces save much smaller (a full Tier 5 furnace: about 350 KB down to 4 KB).
