  1. I'm a beginner potter and I've tried wood firing pottery outdoors because an electric kiln is not very accessible for me. My small kiln is about a bit bigger than 2'x2'x2' and made from regular red bricks with a regular grill grate halfway to place pottery. As you can probably tell, it has terrible insulation and I can never get it to a high enough temp to fire glazed pottery. I can bisque fire and it works but It never gets hot enough to melt glaze, even the low fire glazes I use. I really don't want to ditch this project because I've already put so much time and material into it
  2. Hi all! I am trying to make a small pizza oven out of raku clay. Any suggestions would be welcome, but especially any answers to: 1. How thick should the walls be? 2. Can I "self-fire" the oven by building a small fire inside instead of firing it in a kiln? I dont have my own kiln, and firing it locally could get pricey.
  3. My 6 week online course on Alternative firing techniques begins on Nov. 2-Dec 11 https://www.teachinart.com/alternative-firing.html. see more courses available online at https://www.teachinart.com. Marcia
  4. Any thoughts on why this happened. Just finished a batch of wood fired Raku pieces with unique results. On some pieces I leave bare clay areas so it turns black in the reduction, however this time the bare areas have a silver appearance. I use a copper penny glaze and fire beyond cone 08 when doing a wood fire, and had the same results on paper clay and regular raku clay. The results were ok and I may try to repeat the results. Not sure the attached photo shows this very well. The fish head and area around the fish on the tile have the silver look.
  5. Hi friendly pottery community! I am in the process of building a raku kiln from an oil drum, and I have been scouring various sources online and in books to try and answer some questions but have had no luck! I thought it might be easier to just ask. 1. What kind of burner should I buy? The raku burner kits from pottery suppliers seem prohibitively expensive, and I wondered if they are putting a big mark up on something which could be bought cheaper from a builders merchant or similar. However, as I am new to this and don't really know much about burners, I don't want to cut costs an
  6. Dear Community As everyone is self-isolating here in the UK, I'm encouraging my students and others to handbuild at home and I want to enable them to fire without a kiln in as simple a way as possible. It gets very frustrating for beginners to be unable to fire work and I want to maintain their enthusiasm. We are using the kurinuki method so that there will be no joints to break open. I know that there are some Japanese firing methods for low temp work using small containers but I can't find the videos again on You Tube. I've been trawling the internet but not come up with what I am
  7. I fired 20 4"x4" raku tiles today and all but 4 broke either during the firing or as soon as they were removed from the kiln. I did fire them propped vertically on ceramic brick so I could remove them with tongs. They were hand built tiles with leaf impressions using Standard Ceramics 239 Raku clay. They cracked in half or close to in half. What caused them to crack? (I have been doing raku firings for 40 years). Diane
  8. I'm experimenting with Wayne Higby's Raku glazes....Higby Canyon Orange, Higby Water Blue, Higby Green, and have not yet hit the "sweetspot" for glaze maturation. They seem tricky and have tried different thicknesses and temps, with minimal success. Been trying in the 1800-1900 degree range. Anybody out there using these glazes with success and can direct me to what temp you're firing them at? Thanks, Mike Brown, LizardHill Pottery
  9. What is the highest cone temp you have reached in your Raku kiln- ill be using Propane for the fuel source.
  10. This book has just been released and focuses on kiln firing fir Raku, Pit, and Barrel plus high fire wood kilns. The galleries are full of beautiful work by many ceramic artists. I am excited to be included along with many others. One piece of mine is an Obvara pot with sodium silicate crackle surface and the other in an installation of terra cotta paper clay books pit fired during my residency at Archie Bray. I used the train kiln and a pit. The installation is a memorial piece for 9/11. Marcia
  11. What foods, if any, are safe in a low fired vessel? Specific ally, can I keep tea bags in one? Fruit like apples or peaches? Thank you

    Copper & cobalt oxide glazes applied to bisque fired (950oC) pieces. Fired in a dustbin raku kiln at recent kiln building workshop. (1000oC) then plunged into sawdust to reduce.
  13. Hi, I currently do smoke firings in an oil drum, fired with wood, but I would like more control over the temperatures reached. I’m thinking of building raku kiln from another drum and trying saggar firings. One question I have is about regulators. I had always intended to use a high pressure regulator but have found it difficult to source an inexpensive change over regulator (I want to be able to connect two gas bottles up) for high pressure systems. There seem to be plenty of change over regulators for low pressure systems, so I was wondering if it would ma
  14. Hi guys, I have been trying raku firing at a center where I was introduced to ceramics few months ago, So far I have made some vessels but they are not suitale for water retention. I wonder if there is a way to make raku vessles waterproof? I have heard of a product called Thompson Water Seal in USA. and someone suggested to coat the vessel internally with a mixture of boiled starch so as to seal the clay. Any suggestion? I live in Europe, so any specific product I can get my hands on without incurring in huge import fees is very much appreciated :) Thanks for your inputs. Pierpaol

  16. In this hands on workshop learn to use mica to create subtle colors and lustrous effects with different alternative firing techniques. Attendees will also make a piece from micaceous clay from New Mexico which has glittery effects from the mica, and special insulating properties. Date: February 23-24, 2019 Time: 9 AM to 4:30 PM daily Fee: $300 for non-studio members $275 for members of American Ceramics Society So-Cal, Ventura County Potters' Guild, Clay Artists of San Diego, and AMOCA members Attendees will need to bring: 6-8 medium sized bisqu

    On Tuesday some friends helped me install the new lid with counter weight in my kiln shed. On Monday same friends dugs a hole for gravel for my raku kiln. I filled it with gravel and laid the half cinder blocks. After I put the cinderblocks down, they moved the frame in place. Today I raised the floor to a double cinderblock height . This weekend I will work of the stainless steel chamber lined with fiber. Beautiful weather after our early snow last week.
