Deruna: A Spanish Workshop Notebook for Lime, Plaster, and Decorative Mouldings

Field notes

Deruna organizes its material as ten Spanish-language workshop sections, moving from the behaviour of lime and gypsum to substrate preparation, Venetian stucco, marmorino, terraja mouldings, rosettes, colour, and repairs. The notes distinguish quicklime from powdered hydrated lime and specify that fine polished work may use paste rested for one or two years. Safety guidance is concrete: slaking is described as a hot, splashing reaction requiring eye protection, gloves, covered arms, and ventilation.
