Photography, x-ray, rain and chess; what could all these things possibly have in common? Believe it or not silver! This episode of Scope explores the world of this shiny element. We take a look at the ancient art if silver smithing, find out what science there is to cloud seeding and find silver that is being recycled from a pretty unexpected source. SILVER 101Dr Rob takes us through the basics of silver; from mining it, to its many uses. This shiny element comes in first place in our minds! SILVERSMITHSilversmithing is an old craft dating back thousands of years where ordinary pieces of silver are turned into works of art. Using hammers, stretchers, shapers and many other tools Ken Gray from Gray Reid Gallery shows us how he creates intricate objects like dinosaur chess pieces out of silver.EXPERIMENT: TARNISHING SILVERUsually the tarnishing process of silver happens over many years, but there is a way to speed up the process. Elizabeth shows us how to speed tarnish silver cutlery with a little help from different food items that are high in sulphur.MEDICAL USE OF SILVERSilver has been used in medicine for centuries and is found to be a good antimicrobial and anti-inflammatory agent. Nurse Practitioner Michelle Gibb from the Wound Healing Service at QUT explains exactly how silver helps her treat patient's wounds every day. SILVER IN FILMIf you haven't caught on to the digital craze and still use a traditional film camera, you are taking photos with a film that is covered in thousands of pieces of silver halide crystals. Mark Kimber a senior photography lecturer at UniSA explains exactly how silver plays a part in photographic film.CLOUD SEEDINGBelieve it or not, silver can help create rain! Cloud seeding is when silver iodine is dropped out of planes or released from ground based machines and into clouds. Meteorologist Steve Siems from Monash University explains the process. XRAY RECYCLINGEver wonder what happens to Xrays when they are no longer needed? Xrays actually contain silver and are sent to a refinery to have the silver extracted for reuse. Adam Horner from Siltech takes us through the process of making solid silver from xrays.So don't forget to tune in as Dr Rob wins the silver medal and proves once again that the ordinary really does become extraordinary under the SCOPE! |
