Before 1693, worked with pharmacists while studying with them. He was sort of an itinerant physician/pharmacist.

1694, became Privatdozent in chemistry at Utrecht.

April 1695, City Fathers of Utrecht provided him with a laboratory.

1698, became Lector in Chemistry at Utrecht, starting salary of 250 guilders, various raises later brought it to 600 guilders.

Also received various lump sums for the dedication of some of his published works.
