Investment Casting with Salt Cores Investment casting is used to produce precise components with complex geometries. Salt is an interesting material for this technology. Salt cores are produced by injection casting of molten salt, which produces casting moulds with high mechanical and thermal stability and smooth internal surfaces. The salt Read more…
from a Central European perspective, the use of salt as a construction material sounds little attractive at first sight. In periods of extended rainfall, a salt construction risks to dissolve and disappear. Combining salt with other materials is difficult, because salt is corrosive. Salt Construction Materials Attract the Interest of Read more…
Geo Engineering to Counteract Global Warming The conversion away from fossil energy sources is happening only very slowly. Political inertia to agree on common global rules and regulations is enormous. Engineering of the earth’s climate has therefor been suggested as an approach to help counteract global warming. One suggested technique Read more…
In a series of blogposts, I will describe some little know smaller scale uses of salt: Salt Used for Geo-Engineering In a recent post, “Salt in ancient customs – cruz de sal”, I wrote about the ancient Spanish custom to avoid hailstorms by spreading salt in the form of a Read more…
