Sadolin passed the preliminary exams at the University of Copenhagen in 1890 and then worked for half a year in a mechanical workshop.

He was considered a promising student but temporary visual impairment led him into the theoretical and practical study of dyes.

Burial finds in Egypt had recently brought attention to encaustic paintings, and this inspired him to conduct a series experiments successful with wax-based dyes.

The product range was constantly expanded and A/S Kemisk Værk in Køge was established as a manufacturer of dry pigments and aniline dyes.

Sadolin owned a large collection of classical Dutch, Italian and Spanish art.
