Linseed oil is used to slow down drying time of oil based paints, not a sealer for wood projects.
My grandfather told me of painting the outhouse with paint thinned with linseed oil the day before halloween, those damn kids would tip over the out house and this was a way to find the culprits, undried paint on them and their clothes.
I lived with my grandparents until I was 6 years old in Ohio on their farm. We run all these threads here on being green, my grandpa was a “junkman”, among other things, we would cruise the alleys of Columbus, collecting rags, metal, cardboard. He would go to a concreted company and get pre-stressed columns that were F-ed up and let me hammer all of the concrete off them for the rebar. I guess he was a recycler.
My grandma, grew almost everything we ate, 200 acres of corn, beans, squash, tomatoes, fruit trees and when it came to salads, she would go into the yard and come in with dandelion and mustard greens.
Everything she grew got “putup” for the winter, mason jars lining the basement.
In the fall, they would fill the galvinized tub with hog fat and wood ash and build a wood fire under it, when it had cooked off all of the water, what was left behind was “soft soap”
It was a trip to see a chicken get it’s head cut off and keep running around the yard headless.
Daisy the pig thought it was a dog, would follow you everywhere, even to the slaughter house, poor Daisy.
There was a pump at the kitchen sink for water in the house and a pump in the back yard too, I got washed each night with a “wash rag” and once a week my mother and grandma would fill the galvinized tub with water in front of the coal stove and my brother, sister and I would get our baths. That cast iron stove, had an oven, water heater tank and my grandma was the best cook one could imagine.
All this is part of why I am sort of the Mr. Wizard that I am today, learn to use what you have at hand and make do with less
