Got the shingles real bad senior year. Almost didn't graduate.

Then what you do is you heat up the steel, you melt the bitumen, and the bitumen will flow into these micro cracks, and the stones are again fixed to the surface.

Trapped underneath the boreal forest and wetlands of northern Alberta are these vast reserves of this sticky, tar like bitumen.

And then interestingly, that building to then be clad in the oldest technology, which is the kind of hand cut shingles.

Having each some shingles of thought well dried, we sat and whittled them, trying our knives, and admiring the clear yellowish grain of the pumpkin pine.

So what we can do is use steel wool just to clean pans, and the steel wool we can cut in very small pieces, and these very small pieces we can mix to the bitumen.

Due to weathering, due to U.V. light, due to oxidation, this binder, this bitumen, the glue between the aggregates is going to shrink, and if it shrinks, it gets micro cracks, and it delaminates from the aggregates.

I didn't realize the full effect of this, but I went to Costa Rica and I stayed with these Guaymí natives there, and they could pull leaves off of trees and make shingles out of them, and they could make beds out of trees, and they could I watched this woman for three days.
