It was in 1988, with a course in china makers and traditional techniques, that the Canelas china maker was reactivated, and the following year the company “Ardósias Valério & Figueiredo, Lda” was created, a company with strong family roots, which to this day, and at a pace of progress, they have been asserting themselves in the national and international market, with their natural cleaved slate products.

Over the years this product has gained prominence due to its enormous quality when compared to similar products extracted in other regions.

It can even be said that it is today the largest industry in the parish, employing only local labor, contributing to the maintenance of traditional roofs in the region and offering innovation in terms of products and processes, without neglecting the artisanal nature that characterizes it.
