TAILIEUCHUNG - THE CHEMICAL HISTORY OF A CANDLE A COURSE OF LECTURES DELIVERED BEFORE A JUVENILE AUDIENCE AT THE ROYAL INSTITUTION

From the primitive pine-torch to the paraffin candle, how wide an interval! between them how vast a contrast! The means adopted by man to illuminate his home at night, stamp at once his position in the scale of civilisation. The fluid bitumen of the far East, blazing in rude vessels of baked earth; the Etruscan lamp, exquisite in form, yet ill adapted to its office; the whale, seal, or bear fat, filling the hut of the Esquimaux .or Lap with odour rather than light; the huge wax candle on the glittering altar, the range of gas lamps in our streets,--all. | THE CHEMICAL HISTORY OF A CANDLE A COURSE OF LECTURES DELIVERED BEFORE A JUVENILE AUDIENCE AT THE ROYAL INSTITUTION BY MICHAEL FARADAY . . EDITED BY WILLIAM CROOKES . A NEW IMPRESSION WITH ILLUSTRATIONS LONDON CHATTO WINDUS 1908 PREFACE From the primitive pine-torch to the paraffin candle how wide an interval between them how vast a contrast The means adopted by man to illuminate his home at night stamp at once his position in the scale of civilisation. The fluid bitumen of the far East blazing in rude vessels of baked earth the Etruscan lamp exquisite in form yet ill adapted to its office the whale seal or bear fat filling the hut of the Esquimaux or Lap with odour rather than light the huge wax candle on the glittering altar the range of gas lamps in our streets --all have their stories to tell. All if they could speak and after their own manner they can might warm our hearts in telling how they have ministered to man s comfort love of home toil and devotion. Surely among the millions of fire-worshippers and fire-users who have passed away in earlier ages _some_ have pondered over the mystery of fire perhaps some clear minds have guessed shrewdly near the truth. Think of the time man has lived in hopeless ignorance think that only during a period which might be spanned by the life of one man has the truth been known. Atom by atom link by link has the reasoning chain been forged. Some links too quickly and too slightly made have given way and been replaced by better work but now the great phenomena are known--the outline is correctly and firmly drawn--cunning artists are filling in the rest and the child who masters these Lectures knows more of fire than Aristotle did. The candle itself is now made to light up the dark places of nature the blowpipe and the prism are adding to our knowledge of the earth s crust but the torch must come first. Among the readers of this book some few may devote themselves to increasing the stores of knowledge the Lamp .

• In this workbook
• experiments are elaborated using small scale glassware and equipments from a Small Lab Kit
• developed at the Department of Chemistry
• Faculty of Science
• Chulalongkorn University in Thailand
• This Small Lab Kit was created as a result of the research project entitled “Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” sponsored by Thai Research Fund (RDG 3 07 2543)
• One of the outcomes of this project is the organic laboratory book entitled “Organic Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” written in Thai by professors from 7 universities in this project
• They compiled
• adjusted and tested the experiments taken from several traditional organic chemistry laboratory books using the prototype of Small Lab Kit
• Currently
• some selected experiments from this Thai organic chemistry laboratory text have further been modified
• rewritten and edited in English as appeared in this workbook
