Without a doubt, glass is a true fruit of the art of fire, as it can so closely resemble all kinds of rocks and minerals, yet it is a compound and made by art.Especially Neri's formula of making gold-ruby glass, it was informative and very detailed:

Calcine gold so that it becomes a red powder. This calcination is done repeatedly with aqua regia, pouring it over [the gold] five or six times. Then put this gold powder into a small earthen pan to calcine in the furnace until it becomes a red powder, which will take place after many days. Sprinkle this red powder of gold [gold chloride] over the fused glass. Use fine cristallo, thrown in water many times. This gold powder, given in proportion little by little, will make the transparent ruby red glass; but you must experiment in order to find it.
At first, it is tempting to dismiss this lunar influence as the product of a fertile imagination [of the moon's influence on herb's harvest], but let us take a closer look. The ancients looked to the moon to predict crop growth cycles. The Babylonian calendar, as well as many others, measured out time in lunar phases. [...] In his Natural History, Pliny lays Cato's advice on felling trees in accordance with the lunar cycle. - Fig. 1.8
