January 6, 20188 yr i think i have found a section of drain pipe, that is cast iron to use for a tuyere. is cast iron a good material for a tuyere? how can i test it? it has been outside for some time, it has some paint and rust on it. if i clean it up should i protect the surface or let it gently rust?
January 6, 20188 yr Cast Iron makes great tuyeres. wire brush the paint off, and use BLO to keep it from rusting, or just leave it like it is. Most folks leave it.
