Com os seus relevos ondulados que jogam com reflexos e sombras, a linha Agma Marino introduz um conceito totalmente novo, criativo e disruptivo à arte de empratar, através da aplicação de vidrado de cor irregular e efeito degradê.
The first recorded mention of these glasses, known as biquinhos, appears in a 1901 catalogue of the Nova Fábrica de Vidros da Marinha Grande. This type of glass, part of the diamond point production, is thought to have originated in the 19th century through manual cutting techniques. Later, production was transferred to the pressing method, which is still used today. Interestingly, at the beginning of the 20th century it was considered outdated - but today it's back in fashion.
