The earliest pottery works date back to prehistory. This art consists of molding clay, clay or sand. The pottery creates utensils, ornamental pieces and the most diverse products, which are born of the imagination of man. The materials can be shaped and heated in the sun, in bonfires or in ovens. The ceramics sector in Portugal, which is eminently an exporter, is not the largest, but it is one of the most significant in the performance in an international context. Despite its limited expression in the manufacturing sector, Portuguese ceramics has a long history in the context of national exports, since it is present in more than 150 countries in the four corners of the world.
The packaging glass sector in Portugal is made up of four companies that own six factories, three of them in Marinha Grande, representing 55% of the national production capacity. The export market has increased from 496,000 tonnes in 2002 to 882,000 tonnes in 2012, with the main customers being Spain, France and Italy.
