I have a room where the 1-block-thick roof is covered in furnaces as combination cheap blast protection from creepers above and fast processing for ores/glass etc. I'm considering doing some floor-to-ceiling wool block patterns, but this would jut the wool up against some furnaces and I need to make sure I won't be setting my room ablaze. Can furnaces light things on fire, particularly wool? I'm inclined to believe not but I'd like to know for sure before risking it.
No, furnaces do not start fires
The fire effect from one is purely visual.
No, they cannot. You can safely place your furnace near wool, wood, or anything else flammable and it cannot catch on fire.
In the same vein, torches, while 'on fire' graphically, do not start or spread fire.
