Following a previous communication in the annual meeting of the Society of Glass Technology [1] in 2009 we are presenting some studies of three arcana of glass production in Portugal, one from The Real Fábrica de Vidros da Marinha Grande dated 1793, another from João Augusto de Castro e Augusto de Oliveira e Serra from the period 1875 - 1925 [2] and the third from the Gaivotas glass factory in the Centre of Lisbon which worked from 1811 to 1985.

A special attention was given to the glass colour and to the evolution of the recipes during the years reported. Aside some comparisons made between the analytical results of some museum objects a few glass samples were reproduced using several compositions referred in the arcana to investigate the conditions used to obtain the glass colours.
