He is a widowed ruler of Danland who lives in the mountainous village of Mount Eskel with his daughters Princesses Marda and Miri, where the people make a living by quarrying expensive stone from the mountain called linder. Laren forbids Miri from setting foot in the quarries, making her feel like an outcast in the community.
A Swedish immigrant, [3] Olof Ohman, said that he found the stone late in 1898 while clearing land which he had recently acquired of trees and stumps before plowing. [4] The stone was said to be near the crest of a small knoll rising above the wetlands, lying face down and tangled in the root system of a stunted poplar tree estimated to be from less than 10 to about 40 years old.

For a material that has been strengthened, by some processing method, the amount of force required to start irreversible (plastic) deformation is greater than it was for the original material. In amorphous materials such as polymers, amorphous ceramics (glass), and amorphous metals, the lack of long range order leads to yielding via mechanisms ...
Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand and/or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water. When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid shape.
Bentonite layers from an ancient deposit of weathered volcanic ash tuff in Wyoming Gray shale and bentonites (Benton Shale; Colorado Springs, Colorado). Bentonite (/ ˈ b ɛ n t ə n aɪ t / BEN-tə-nyte) [1] [2] is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite.
The Pantheon in Rome is an example of Roman concrete construction. Caesarea harbour: an example of underwater Roman concrete technology on a large scale. Roman concrete, also called opus caementicium, was used in construction in ancient Rome.
A forge fire for hot working of metal. In metallurgy, hot working refers to processes where metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the material to recrystallize during deformation.
Hempcrete was also used to renovate old buildings made of stone or lime. [9] France continues to be an avid user of hempcrete, and it grows in popularity there annually. [ 10 ] Canada has followed France's direction in the organic building technologies sector, and hempcrete has become a growing innovation in Ontario and Quebec .
