He might be regarded as a forerunner of contemporary chemists. His work and experiments resulted in discoveries of several analytic methods and he was the first to produce hydrochloric acid. Among other chemical compounds Glauber discovered sodium sulfate, which was named after him ("Glauber's salt").
The Chemical Garden (or Silica Garden) was first observed by Glauber in 1646. In its original form, the Chemical Garden involved the introduction of ferrous chloride (FeCl2) crystals into a solution of potassium silicate (K2SiO3, water glass).
