Glauber published some thirty separate treatises during his lifetime and is regarded as the best practical chemist of his day and the first industrial chemist. ‘He was a keen observer, a persevering and successful experimenter and inventor. He was anxious to promote technology and the industrial prosperity of his native country, but by his contemporaries, and by Adelung a century later, he was regarded as a dreamer and a charlatan. As a matter of fact he as far ahead of his time in some of his economical views’ (Ferguson).
