Scientific glass instruments

These pieces are scientific glass work, I have made back in ’90-’92. I had to get all the dust off first! Some of them are my ’final glass exam’ stuff, also the ones with the technical specification and drawing. These drawings show the precise measures the apparatus needs to be. It had to be made fast and properly sized at the same time. These skills are obtained, at base level, after approx. 3 years of daily training.
