A hundred years manufacturing gum rosin.
The history of our family has been linked to the production of resin since the beginnings of the 20th Century.
Pedro Criado was the name of the forerunner in our long involvement in the production of gum rosin and turpentine. Being both an expert and a businessman, he decided to open up four resin factories, and built all of them in the province of Segovia. These factories were located in the small towns of Zarzuela del Pinar, Lastras de Cuellar, and Pinarejos.
The factory that was originally placed in Zarzuela del Pinar is the one that has been kept opened throughout the years. It is around this factory that the resin-making family’s tradition has been preserved. After its foundation by Pedro Criado, the company was renamed Hijos de Tomás Criado (Sons of Tomás Criado). In 1996, the company changed its name again to Resinas Alfonso Criado. Since then, the factory has been operating under this name in both the national and international markets.
