The research on manuscripts provides useful information about the artistic/technical production and the scientific development in the past. However, the reproduction of the ancient recipes is difficult because most of them are described generally or they hide essential information to preserve the production secrets. In this study, four different recipes from the medieval Manuscript H-490 (École de Médicine of Montpellier University, France) were reproduced. The raw materials and the production process of each recipe were discussed from the point of view of the glassmaking, and the final products were characterized. The recipe (31) indicated the preparation of a white glaze, similar to Islamic frits. The recipes (32) and (33) explained the preparation of an “unbreakable” glass; however, the characterization of the final products showed that no changes in the hardness of the glass were obtained. And the recipe (34) described the preparation of a green glass which was successfully obtained.
