In Europe a similar liquid process in open-topped crucibles took place which was probably less efficient than the Roman process and the use of the term tutty by Albertus Magnus in the 13th century suggests influence from Islamic technology. [100] The 12th century German monk Theophilus described how preheated crucibles were one sixth filled with powdered calamine and charcoal then topped up with copper and charcoal before being melted, stirred then filled again. The final product was cast, then again melted with calamine. It has been suggested that this second melting may have taken place at a lower temperature to allow more zinc to be absorbed. [101] Albertus Magnus noted that the "power" of both calamine and tutty could evaporate and described how the addition of powdered glass could create a film to bind it to the metal. [102]

Is Brass Magnetic? What Is Magnetic Brass?". Scrap Metal Junkie. 1 January 2020 . Retrieved 19 January 2020. Magnetism is a property of atoms that arises from the motion of electrons in the atom’s outermost shell. When electrons move, they create a magnetic field, which can interact with other magnetic fields to produce attractive or repulsive forces. In diamagnetic materials, the electrons cancel out each other’s magnetic fields, resulting in no net magnetic field. Lastly, the color of brass can also affect its magnetic properties. Brass that has a reddish color may contain more copper, while brass that has a yellowish color may contain more zinc. The amount of iron present in the alloy can also affect the color of brass.Brass has a good level of resistance. However, zinc reacts with the minerals in salt water. Tin, on the other hand, does not react with the minerals, therefore bronze is ideal for making boat propellers and in other applications that involve salt water.

Bell, Terence. "Here's Why Alloys Can Change the Properties of Brass". ThoughtCo . Retrieved 28 January 2021. It is worth noting that the level of magnetization you achieve in brass will depend on the strength of the applied magnetic field and the constituent elements in the brass alloy itself. Once you take out the external magnetic field, the brass will lose its induced magnetism and return to the original level of weak diamagnetism. Humphreys, Henry Noel (1897).

Their relative permeability is slightly less than one. For example zinc, copper, wood, bismuth, etc.
