The clay industry began here in 1920 when the English Floyd Corporation opened a clay mine and established a factory in the village Romhány. They started the industrial production of stovetiles
using the clay of Felsőpetény.
Long before that, local craftsmen had made stovetiles and other articles for personal use.
In 1949 the mine was nationalized, the production became regular.
In the 70's openpit mines were opened to excívate the fireproof clay.
After 2004 a new chapter started in the life of the mine. We had to completely renew our product
line. Recently Agyag-Ásvány Ltd's (Clay-Mineral Ltd.) core business is Kaolin
mining and processing.
Today there is no longer underground mining operation but 2 open pit mines are being continously operated.
