These amazing Citric Acid crystal microscope image coasters would make a great gift for a chemist or science / chemistry teacher. All the microscope photographs taken by myself and all the 4 different images came off the same slide of citric acid crystals I had prepared.
90mm square mdf coasters printed by dye sublimation to give a vibrant, high gloss, scratch resistant finish.
Supplied in a cellophane bag holding all 4 coasters visible (easy to wrap!) with a description on the back of each coaster.
None of the colours have been altered in photoshop - they are all the colours I saw through the microscope!
If you want to choose your own selection (including a range of non-chemical coasters please see our listings for 4 or 6 coasters of your choice.
