Printed in the United States of America Preface to the Third Edition The idea of this book took place thirty years ago, and it is gratifying that it still has a place in the firework world. The original intention was to produce a straightforward description of firework manufacture in the Western World. It was an attempt to describe what had happened in the past and to make suggestions for good practice at the present time. It was also an attempt to be fairly basic and thereby not offend friends and competitors in the trade who had to make an attempt to make a living at fireworks. Amateurs have wonderful enthusiasm and like true scientists need to know everything—for its own sake. They also want to share findings with everyone else. However, this is in complete contrast to commerce, where survival may depend on the quality of the product or the price at which it might be produced. Needless to say this "edge" can be very costly in terms of hours of research and capital expenditure. Recent years have seen the decline of the Western firework industry. The story is the same for almost every country where it has become uneconomical to make small fireworks compared to the price at which they can be bought from China. In the U.K., for example, there were ten manufacturers of small-shop fireworks in 1960, but there are none left in 1998. In the U.K. only Kimbolton Fireworks makes a full range of display fireworks with two other firms making special effects for the stage, etc. Much of the material from the Far East is cheap and only partly reliable. It is also a boon to the ever-increasing numbers of unspecial- ized (and often legally ignorant) importers who bring in and distribute explosives in much the same way as bananas. The Civil Service, in the iv Fireworks Principles and Practice U.K. at least, has been less than effective in the control of these illegali- ties in latter years. It was not so in the past, and while the EEC gets the blame for most things, it is clear that some of our partners in the EEC are much better 'at looking after their own' than is the case in the U.K. This industrial decline is a great tragedy, but it is generally agreed that there will be a place for the present for those manufacturers able to make a good quality product. Those people willing to make this capital outlay need a Civil Service which creates a level playing field. In 1998 a high profile manufacturer is constantly bombarded with rules, regulations, bureaucratic nonsense, and more and more costs at every stage. Every sizeable company has to employ unproductive safety ad- visers, subscribe to suppliers of safety information, make space for records and risk assessments. No one can deny that the simple desire for good health and safety management is laudable. In reality it has become a burden with those working in it leaving no stone unturned and sometimes reaching absurdum as they justify their existence. In the meantime companies disappear or transfer their production to the Third World. All this time, the importers increase in number and have the financial gain. It is difficult to predict what the next few years will bring. Importa- tions from the Far East will increase, but it is clear that there are far too many Chinese exporters. Most of them are selling much the same products, and it is always more important to remain competitive than to produce superior products. A Chinese supplier may well sell the same products to several people in a limited market—a policy doomed to a very limited lifespan for obvious reasons. Once again I am grateful to the many friends who have helped to make this edition possible. In particular to friends mentioned in Chapter 1 who have filled out the details about the firework scene in their own countries. I would particularly mention Dr Takeo Shimizu (b. 1912) whom I have known for over thirty years and who has been absolutely prolific in his research for the firework trade. What would we have done without him? Mention must also be made of the late Chris Philip who died in January 1998. The importation fireworks in the U.K had always been a major problem because of the prohibition on the admixture of chlor- ates and sulfur. However, Chris Philip set out to challenge a somewhat negative attitude towards importation at that time. A total ban had been easy to control, but his success then has done no favours to the home- Preface to the Third Edition v based industry some thirty years later. It has not shaken the Government into being more proactive in controlling the quality of what can be sold from abroad up to 1997 either. Nearer home I am grateful to Mark Lancaster, Dr Tom Smith, Tony Cardell, Roy Butler, and John Bennett, the Editor of the excellent U.K. magazine 'Fireworks'. This magazine has done so much to encourage an interest in fireworks and to keep some of the history intact. Lastly, to my wife Kath who has always maintained that I eat and sleep fire- works and talk about them in bed—sometimes. Ronald Lancaster 7, High Street Kimbolton Huntingdon Cambs PE18 OHB U.K. Preface to Second Edition It is now over sixteen years since this book was first put together. Progress there has been, but fundamentally fireworks are much the same as before. Over the last few years one or two important new books have been published along with a number of useful essays on individual topics. Reference has been made to these in the bibliography. I am grateful to a number of friends who have helped with this revision particularly Robert Cardwell the Editor and creator of Pyro- technica. Robert has done much to further the firework cause by the production of this interesting and scholarly periodical. I am grateful to him for revising our notes on the contemporary American firework industry. Similarly Bill Withrow of Euless, Texas, a good friend over the years has been tireless in his help and encouragement to get this book completed. Mention must also be made of the late Max P. Vander Horck. Max did so much to encourage the writing of the First Edition and when it was completed he maintained that if Weingart's Pyrotech- nics was the firework maker's Bible, then 'Fireworks, Principles and Practice' was the New Testament. I am also grateful to Dr. Tom Smith, Mr. L. Jackson and to Mark Lancaster for their help with photographs and drawings, to Tony Cardell and Walter Zink for some extremely helpful information, to Mrs. G. Crocker for allowing material to be used from the Gunpowder Mills Study Group and to Mr. J. Salmon for his excellent drawings of the Faversham Gunpowder Mills. Last and not least to Mr. Bryan Earl who kindly allowed me to quote from his splendid, scholarly work 'Cornish Explosives'. Ronald Lancaster 7, High Street Kimbolton Huntingdon England. Preface For many years Weingart's "Pyrotechnics" has been regarded as the amateur firework enthusiast's Bible, and it was news of the re-print of this work in 1968 which prompted the writer to suggest a revision of it. As it happened the suggestion came too late with the result that a new work has evolved. From the beginning the writer was anxious to share the task of writing this work, and accords grateful thanks to the other three contributors:- Dr. Shimizu, who very willingly translated part of his book "Hanabi" from the original Japanese. The script of chapter 19 is more or less as he translated it, and a great credit to him. To the best of our knowledge this was the first treatise on Japanese firework manufacture in the En- glish language. Ronald Hall, one of my long-standing firework friends who has long experience as a chemist in the explosives and firework industries. Has also been responsible for the introduction of polymerizing resins into commercial firework manufacture and is especially interested in foren- sic aspects of explosives. Last but not least my thanks go to my teaching colleague and friend Roy Butler; an able firework maker who has given even more of his time to write a precis of available historical records, adding also more up-to-date material. Turning to the general preparation of the book, I would like to express grateful thanks to Peter Smout Esq., M.A., Senior Master at Kimbolton School who has so kindly read through the script and made many helpful suggestions. Helpful comments have also been made by Peter Watson, Esq., B.Sc. Senior Chemistry Master at Kimbolton School, Dr. Herbert Ellern, the x Fireworks Principles and Practice author of Military and Civilian Pyrotechnics, and Mr.
