I'm a big reader, but this month deals with being on the other side. My first two books Raku Glazes http://www.rakuglazes.com and Raku Secrets http://www.rakusecrets.com are now available on Amazon.com http://www.garyrferguson.com/myamazonbooks so if you frequent that website check them out. If you already have a copy of either (or both) and love them, please add a review on Amazon. I would appreciate it. Also the new book Fired Up With Raku by Irene Poulton which I contributed to has been published and is available at: http://www.garyrferguson.com/firedupwithraku.htm This is published in the UK and availability in the US is a little tough. Finally, my latest ebook (not Raku related) Hypnotic Auctions is now available at: http://www.hypnoticauctions.com If you sell your work on eBay or have wanted to, this ebook should reveal the methods to attracting customer and getting higher bids on your listings. Yes, I know the above was all shameless plugs, but it's my newsletter after all. Don't worry. Good content is below for your Raku-ing enjoyment. As always, I look forward to your feedback, suggestions, questions, and article ideas at:

~-~-~ "I must thank you for all the great recipes. I was a bit stuck for new recipes. I'll be here for thirty years trying all these out." - Simon D. http://www.rakuglazes.com ~-~-~ * Hang Tags in time for Christmas I read an interesting article in Pottery Making Illustrated about Hang Tags by Frank James Fisher a couple weeks ago that I would like to mention. If you sell you items at craft fairs or even out of your own studio, you may want to take a look at this article. It provides some great insight into how to create a simple, but professional looking hang tag that adds to the look of your pieces instead of being the typical price tag "eye sore." So if you are interested in improving the look of your items for sale (the holiday selling season is right around the corner) then check out his article at: http://www.potterymaking.org/issues/2006-0910/Fisher.pdf (Note: I'm sure how long the link above will be available) Also if you would like to see some great "realistic" Raku check out his website at: www.frankjamesfisher.com ~-~-~ "Our class fired again last night, and the instructor followed your tips and voila. Boy do we have copper. Its great knowing we can do it, and I really appreciate your help. Thanks again!"-Shannon P. http://www.rakusecrets.com ~-~-~ * Unstoppable Glaze Len wrote: While I was receiving instructions concerning the repair (installation of new elements) of my electric kiln, the expert told me to be sure to remove the glaze drips from the bottom of the kiln, as they would eventually produce a hole in the bottom of the kiln as they gradually work their way through the brick. Yesterday, during a Raku fund raiser, a piece of kiln shelf wound up with a hole completely through the shelf. I saved the shelf piece, which clearly shows a hole and glaze on both sides of it. Is this the same phenomenon? Can glaze actually work its way through glaze shelves if you don't chip it off and apply kiln wash? Very interesting question. First I attempt to explain the glaze on brick phenomenon. Firebrick is very porous (full of holes like Swiss cheese). When the glaze drips on the brick it fills some of these holes. Then when it cools (and shrinks), it actually breaks some of this fragile brick. If the glaze is left on there for repeated firing, the glaze will continue to liquefy, seep further into the brick, cool, solidify, and break/crack the brick more. If this process repeats enough times, yes the glaze can "eat" all the way through the brick. Now a kiln shelf on the other hand is a little different. A kiln shelf is made of much tougher stuff and is not as porous as kiln brick. The main reason you want to get the glaze on kiln shelves is to keep them smooth and flat and to prevent them from fusing to kiln furniture or your pieces. I would think it would be highly unlikely the kiln shelf developed a hole with the same process as the kiln brick above. I would think someone would have had to grind a hole through (or almost through) the kiln shelf (by repeatedly removing dripped glaze) and then possibly during the lasting firing a glaze drip finally "broke" through the shelf. Just a guess, but I think it would take more than just glaze to "eat" through a kiln shelf. ~-~-~ After reading Sue's book I discovered dozens of tips, techniques, and methods of creating Raku beads and jewelry that I never would have thought of. The hundreds of color photos are not only instructional but inspiring as well. There is a new idea to try on almost every page. This book is a gold mine!" http://www.rakubeadjewelry.com ~-~-~ * Two Halves of the Same Pot Doug sent in the following: I have only been "pottering" since last November and have found that I enjoy Raku firing more than anything else. We only Raku fire once a month and I attend each one. We have a very limited inventory of Raku glazes available to us but the one I like the best is the Glossy Green. I always seem to have a problem with it – after removing the piece from the reduction chamber (garbage can with waded up newspaper) half of the piece will be very shiny and impart lots of color while the other half will be dull and maybe even a "bubbled" finish to it. We just had a firing last Saturday and the top of the piece was just beautiful with lots of color and was very glossy but the bottom had a very dull finish to it. Is there a way to make both top and bottom halves of the piece come out the same? I have your book, Raku Secrets http://www.rakusecrets.com and have enjoyed it very much. Well, I can't know exactly what is occurring in these situations, but I can give you some insight that may help you out. There are two primary factors as you can guess: the firing process and the reduction process. Generally in a Raku firing (because of the speed), the bottom of a piece get hotter that the top of a piece in a kiln. This can lead to runs on the bottom with the top just reaching maturity, or it can get bubbles on the top of a piece when the bottom is just mature. The bubbles are caused by gas escaping during the firing and the glaze not having a change to heal itself by reaching maturity. So the solution here would be to fire slower and soak at the final temperature for a little longer to make sure both the top and the bottom reach about the same temperature at the same time. Now during the reduction process you can have two different impacts on the piece as well. When you place the piece into the reduction materials the bottom of the piece will often sit right in the combustibles, which can lead to creating marks in the glaze and more black marks from the carbon. Both of which can dull the pieces. The solution here is to use fewer combustible materials and also place one or more bricks in the bottom of your reduction chamber set the piece on to keep the piece elevated out of the reduction materials better. Hope this helps. ~-~-~ Discover the secrets to creating multiple streams of income using the power of eBay.

Has anyone read articles on how the Raku process effects the environment? Although this is probably not a popular subject, does anyone have thoughts on this or get customers inquiring about the subject? I have to admit. When I first received this email my first reaction was, you've got to be kidding. How could this be affecting the ozone, etc. But then I didn't a little looking around on the Internet and I am a little more "educated". First I couldn't find any articles specifically addressing Raku and Global Warming (so I guess this is the first). But on Wikipedia I read that Global warming is primarily attributed to increased amounts of carbon dioxide and other greenhouse gases (water vapor, methane, nitrous oxide, ozone, etc.) The first of these, carbon dioxide is produced in several ways, which include combustion of organic material and even the act of breathing (oxygen in - carbon dioxide out). So given these facts, I can say that yes, the Raku process does "contribute" to Global Warming ... but so does forest fires, barbequing, driving a car, water evaporating from the oceans, cow burps (methane), visiting the dentist ("laughing gas"), and even breathing, along with a jillion other things. But do I think it contributes significantly? Of course not. How many hours (or make that years) would I have to fire my Raku kiln to equal the impact of one forest fire? Or one oil burning car? Or one industrial factory? I think the comparative impact is miniscule at best. So I personally would not worry about adding to the Greenhouse effect, but others might look at any possible increase as bad, so if this is you, then you may want to find another art form to express yourself with. I, on the other hand, will plant a tree and keep Raku-ing. ~-~-~ "It's all your fault! I was up all night reading "Raku Secrets". I have been Rakuing for about ten years, and still so much to learn.
