| It would be much more helpful if you’d explain why you think people are wrong than acting like they’re stupid. I get tired of people quoting AI all the time too but it’s actually quite a common theory that long predates AI. I think some people are getting confused between ferrous oxide and ferric oxide. Both are iron oxide. Ferric oxide (rust) is red and still used as pigment today. As for where you could get enough to paint a barn, I found this on AgTalk.
Red iron oxide paint could and was made ON the farm. Farmers grew flax for making linen cloth. The seed oil we know as linseed oil. Linseed oil and pigment makes paint. A good paint. Slow to dry and won't clean up with soap and water. The iron oxide pigment is found in layers in many a river bluff rock layer. Just need to be ground and the mortar and pestle has been a tool for many millenia of human history. Its a workable tool for extracting oil from flax seeds too. Flax fibers also made decent rope so it was a multiple use crop, maybe even with critter edible young leaves. Iron minerals are fairly abundant in the earth's crust, my Merck chemical index says 5% but they might not show up in quantities suitable for mining for iron ore every where, but for enough pigment to paint a colonial barn just takes a bucket or two. A seam an inch thick is plenty. A foot thick is enough to go into paint production for the whole colony. | |

Is There Any Truth To This?
