If you can get the book by Eward Notter, you will have all the information you'll ever need. Sadly the book is long out of print and you'll pay hundreds for it, IF you ever find a copy. The author is an internationally renowned sugar artist who now teaches at his pastry arts school in Florida...read all about him at: http://www.notterschool.com/continuing.html
. Presumably he wants ppl to do his courses rather than learn everything out of his book.
Herve Boutin taught at Le Cordon Bleu Institute in Sydney about 10 yrs ago - and I'm sorry but I do not know if he still does. Perhaps you could look them up and they may redirect you if he does not? He's well known as the authority on blowing, pulling and handcrafting sugar. The book I have by him is a slim volume from the Cake Decorating Skills Series (Book 2) - Sugar Pouring, Pulling and Blowing (try eBay, it occasionally comes up). I have toyed around with various techniques, but would really love to do a course, too (hey - if you find out about any short courses, can you let me know and I may be able to come down to Sydney to do it with you?). I am *this close* to buying a bulb and tubing set ($170!) to start blowing sugar, but really don't have unlimited time to experiment with all the other work I have on!
I got interested in the art after doing croquembouches with spun sugar...there's so much more you can do.
Can you pm me if you find out anything more about courses? That would be excellent!!
