Rural Shots + Replacing Sauna Stones
There were lots of hey bales in the fields.
This farmer has been collecting hey bales from his fields. Notice the migratory birds above the treeline.
My wife asked me to wash the sauna stones. They collect dust over a long time, which may be a fire hazard in an electric sauna. I did as she asked me to do.
Emptied. The stove contained about 20 kg of stones.
Most of these were fine. But...
WTF?? I could fracture these manually. Artificial?
Anyway. I bought new ones. Only €9.90.
Good stuff.

The löyly stones do become brittle after some use, it's pretty normal. They need to be changed every few years, depending on how heavily they are being used. I guess there are some stones that can handle heat better than others though.
The strange thing about those stones was that the inside seemed to be made out of a different material than the surface.
It looked like iron deposits. Rust forms from iron reacting with oxygen (burning), and the kiuas is a very hot place. I wouldn't be surprised if it speeds up the rusting process in the stones. Throwing water on the stones also helps.
Very good point. Those stones must contain quite a bit of iron. They look rusty on the inside. Heat really does speed up oxidation, which is evident from the rusty hulls of military vehicles that have been hit. The metal is rapidly oxidized and the vehicles look as if they had been exposed to the elements for decades.
