A fume funnel is an upgrade for the Witches Oven that increases that increases the speed (over a normal furnace) by an additional 10%, and increases the chances of a by-product being produced by a further 25%. The Fume Funnel must be positioned next to the left or right of the witches oven with the same facing. Up to two funnels can be attached to one oven. It is possible to place a funnel between two ovens for it to benefit both. A third fume funnel can also be placed on top of an oven to make it look better and also to increase its speed by a further 10%.
The Fume Funnel can be upgraded to a Filtered Fume Funnel by crafting it with a Fume Filter. The Fume Funnel is crafted with Iron Blocks, Empty Buckets, a Lava Bucket and a Glowstone block. |
