Macroscopic Properties
...ample & ammeter in series. 2/ Lustre: o Determine if it is shiny, glassy, metallic, pearly or dull. 3/ Heat Conductivity: o Heat the end of a metal rod to red hot and hold it against the material for a few seconds. Determine if the material gets hot, softens, chars, melts, burns or if there is no visible effects. 4/ Flammability: o Place the material close to a small flame or use the metal rod, heat it up then place it close to the metal. 5/ Malleability: o Bend the material or use a hammer. 6/ Solubility: o Dip a part of each sample in boiling water for 60 secs and observe.
