Smalt is produced by melting a mixture of roasted mineral smaltite, quartz and potassium carbonate, which yields a dark blue silicate glass, which is finely ground after the production. [166] Smalt was widely used to color glass and as pigment for paintings. [ 167 ]
Benzyl salicylate is a salicylic acid benzyl ester, a chemical compound most frequently used in cosmetics as a fragrance additive or UV light absorber.It appears as an almost colorless liquid with a mild odor described as "very faint, sweet-floral, slightly balsamic" by some, while others smell nothing at all.
