Funnel Glass slides Cover glasses Bottle with screw cap Stirring rod Dissecting Needle Spatula Graduated cylinder 3 METHOD With the graduated cylinder pour about 20 ml thinner into the bottle. Add about 1 g sulphur powder and mix well. Place the bottle with a loose cap on the heating plate and switch the heating plate on. Mix regularly Once the solution has reached a temperature of about 100 °C filtrate a part of it off in the test tube. With the aid of the stirring rod put a drop of the hot solution on the glass slide. Let de solvent evaporate. Place a cover glass Observe under the polarisation microscope. Figure 3: Lucky Zoom 5Mp camera Thinner has a rather strong smell. Conduct this experiment in a well-ventilated room. 4 RESULTS As can be seen in Figure 5, small needle like crystals form almost immediately in the test tube during filtration. The pictures below were taken with the Euromex ML2000 polarization microscope and the Lucky Zoom 5Mp camera. The captions refer to the objective lens used when taking the picture.
