More Oak

At the beginning of the end of the last glaciation, Ireland was connected to England, England was connected to Europe. As these land-bridges sank below the rising water, and they were heavily forested, they took their trees with them. They're mining those 1st growth oaks today, 90 feet to the first branch, as they're mining 1st growth cypress from rivers in the southern US. Trees that are thousands of years old. This leads to further research into the nature of rot. An added feature of the oak harvested from the Irish Channel is that it should be quite well fire-proofed. Salt. I'd love to see a board cut from those logs. I've seen the cypress, and it's quite beautiful. I used some of it, for a den in Colorado, at $24 a board foot, and it finished like a lush dream. A full cord of oak is around 23 million BTU's which is about the same as a hundred gallons of fuel oil. Thin splits of yew coppice, after soaking, made a good attachment for planks, and the first boats were (probably) stitched oak planks, just enough framing to hold it together. Still, it wasn't building ships that denuded the forests of Europe and England, it was the iron plow. Iron, generally, because it used so much wood, but the iron plow in particular, because trees got in the way of planting. A yearly row-crop, guaranteed income, looks pretty good when you've been making your own soap, washing with rainwater, and always run out of food in March. I've been collecting oak galls, toward making a small batch of ink. This has interested me for decades. I've made ink from soot, but it didn't actually penetrate the paper fibers, it sat on top and rubbed off. I got sidetracked into paper-making, wondering about fiber, and didn't think about ink for years, then this fascination with oak galls. You need a penetrant, a binder, and a coloring agent. This is usually iron sulfate, crushed oak galls, and sticky sap, diluted, everything held in suspension. You can substitute egg whites for the sticky sap. I don't even use ink anymore, but that doesn't mean that I don't want to know more about it.
