SCIENCE PENDANT - CITRIC ACID CRYSTALS BY POLARISED LIGHT MICROSCOPY (P4)
A solution of citric acid was evaporated on a microscope slide to form crystals. By viewing these crystals using polarised light microscopy, amazing and interesting colours and patterns are seen. This is due to the crystals forming regular arrays and interfering with the light path to give the colours seen (no colours were changed using Photoshop).
These colourful and interesting microscope photo pendants are 22mm in diameter and measure 34mm from the top of the bail to the bottom of the pendant. The pendants are silver plated and supplied with an 18 inch (45cm) silver plated chain. The image has been printed onto glossy metal which is sealed underneath a glass magnifying dome. As the images are printed onto metal there are reflections from both the metal and the glass resulting in the image having more 'depth'. Great gifts for teachers or recent graduates. Or anyone who has an interest in the world around us.
Supplied in a gift box complete with a description of the image.
