The present work aims to study the glasses commonly named crystal glass produced in Portuguese factories from the 18th to the 20th centuries through their arcana or batch books. Recipes for colorless crystal glasses were selected, analyzed, and reproduced in the laboratory. Five recipes were chosen from the Marinha Grande arcanum, five recipes from the Gaivotas’ Factory arcanum, and three recipes from the Castro and Oliveira Guerra arcanum. To characterize the composition and thermal‐physical properties of reproduced glasses, different analytical techniques were used such as micro‐energy dispersive X‐ray fluorescence, µ‐ Raman spectroscopy, differential scanning calorimetry, dilatometry, Vickers hardness, optical microscopy, and UV‐Vis absorbance spectroscopy. The selected recipes were proven viable for reproduction and the obtained glasses presented good thermal properties that allow the workability and creation of objects. It was also proven that there is a similarity in terms of chemical composition to some of the historical glasses attributed to Portuguese production in Portuguese museums.

从三个18至20世纪的葡萄牙玻璃秘方中复制水晶玻璃

本工作旨在研究18世纪至20世纪在葡萄牙工厂中生产的通常称为水晶玻璃的眼镜，这些眼镜属于神秘物品或批次书籍。在实验室中选择，分析和复制了无色水晶玻璃的配方。五个食谱是从大马里尼亚选择的奥秘，从Gaivotas 5个食谱“工厂的奥秘，并从卡斯特罗和奥利维拉格拉三个配方奥秘。为了表征再生玻璃的成分和热物理性质，使用了不同的分析技术，例如微能量色散X射线荧光，μ拉曼光谱，差示扫描量热法，膨胀计，维氏硬度，光学显微镜和UV-Vis吸收光谱。所选配方经证实可复制，所获得的玻璃杯具有良好的热性能，可进行加工和制成物品。还已经证明，在化学成分方面与葡萄牙博物馆中归因于葡萄牙生产的某些历史玻璃相似。
