Keyword: Mineral
Layman's explanation: Halloysite was first discovered in 1826 by Berthier in Angleur, Belgium. Halloysite clays are mined in Northland, New Zealand. There are two sites in Northland where halloysite is found: Matauri Bay and Mahimahi. Halloysite is used to make clay that can be used in many different things. Clay is exported to 24 countries for the manufacturing of tableware such as porcelain, bone china and fine china. It can also be used for hi-tech ceramic applications. Finally, halloysite clays can be employed extensively as suspension agents in glaze preparations.
