  1. Maganese is what they use to add color to buff and darker clays, correct? I haven't had that problem with red clays or moroccan sand, etc. Weird.
  2. I am a high school teacher. The way my building is positioned, it is really hard to get sunlight to help with drying out slabs to leather hard. Since we only have 45 minutes each class, then 10 minutes to clean up, wheel thrown items can sit on their shelves overnight and be ready to trim 24 hrs later. However, with slabs, unless there is sun, forget about it. My morning students can't naturally dry slabs. And 24 hrs is too long for thin slabs to sit out before going too far towards bone dry. I've tried a fan, but it just doesn't seem to be that great, very uneven. And it Tak
  3. Okay. I'm trying out a Laguna Clay Cone 5 called Buff with Sand. I have used a Cone 06 Buff with sand with no issues itching wise. However, It seems like the sand in the Cone 5 clay is much more flecked, white and dark sand. When I wash my hands, it seems to stay on the skin more. Kind of like going to the beach and not getting all the sand off your hands or feet. I swear, I feel like I get itchy or even irritated skin, like allergic reaction? Is this possible?
  4. I replied before I saw your second response... I may have misread... Are you saying that 2050 up to 2190 in your recommended schedule is for Bisque or for Glaze? I have been Bisque firing to Cone 04 (candle for 12 to 14 hrs, then start). To be safe, I've been going 108* / hr all the way up to Cone 04 (1940 or until the cone bends) with a soak at 1200. Well... I did that Cone 5 Glaze fire last night. 200* / hr up to 2000; 100* / hr up to 2150; 50* / hr up to 2250; Cone bent at 2208 That's the 2nd time I've gotten the cone to bend at exactly 2208 with this 50* at
  5. Amazing. Great stuff. I was wondering why the Orton chart didn’t say glaze or bisque. So what do you think about the last hundred degrees of my firing for a glaze firing? 108° to 124°, or will 50° an hour give me a soak? It’s a soak necessary? I hear people talk about flattening out the glazes. I’ve got five minutes to make a decision or my kiln goes into 50° in our the last hundred degrees
  6. I am firing to cone 5. So many opinions on firing schedules for glaze firings. I have a 28 cu ft Geil, Gas, Downdraft, Fiber kiln. Orton says the cone will bend around 2187 F if you go up 108 degrees / hr. I did that once, got great results. I've been in the habit now of going up 100 degrees /hr from 2000 F to 2100, then slowing to 50 degrees / hr up to the cone bending That means a few hours from 2100 F up, which is a long soak, trying to get Oxidation, abut afraid I will burn out colors like yellow and Pink. I'm torn to go back to 108 hr, but that slow 50
  7. Hello. Does anyone in Los Angles have a Peter Pugger (hopefully a 20 or 30) I can come try out? I would just use clay you already have... chat a bit... bring you lunch or a coffee. I am desperate to try one to resolve my purchasing issue. I teach high school, and my last 2 pug mills (Bailey and Shampoo) had big issues. Peter Pugger does not have a single business in LA to test out a unit.
  8. I have a lot of experience with pug mills. I have a BAILEY MXP-70T. It sat for 5 years bagged up from the last teacher who never used it. It is a dual auger. I come on board and It worked for a while then the motor kept getting locked up and something broke in the motor area. Amazing mixes, but took forever, small hopper, and had to be hooked up outside my classroom to a single phase, 240v plug outdoors. Now out of warranty. I may sell it to someone who wants to embark on a Pandora's Box to repair it. I just bought a SHIMPO NVS-07. I bought it for the HUGE hopper door (10" x 13"
  9. DO NOT GET THE SHIMPO NVS 07. I have good experience with pug mills. I bought it and it LEAVES HOLES IN THE LOGS. See picture. The tan is new clay out of the bag. Seriously. They grey is recycled clay. The factory says my batches are too wet. Huh? The consistency, as seen wrapped around my finger, is perfect. Now they want to charge me $500 to restock it. I am fighting it tooth and nail. Should
  10. Can adding a scoop of Dry Mixed clay to a batch of recycled clay return it a bit to a stronger (purer) clay?
  11. OMG! I am a high school teacher. I just bought the SHIMPO NVS-07 because it has a huge hopper, but it is a pain in the ass! Not only am I getting HOLES in the middle of the logs, all of the water I add gets pushed up in the lid and doesn't mix into the batch. Unless the batch is perfect, it won't pug without a hole. I mixed fresh clay from the bag, from the Laguna factory, and it STILL made holes. They said it is too wet. I should be able to make a batch a little wetter or a little dryer if I want. 8 hours and pugged 4 boxes of clay. That is a waste of my time. I'll attach pictu
  12. I need to find the best All-In-One clay for cone 5, great for both hand building and wheel throwing I know. That's a tall order. But I can dream. I have a pug mill and don't want 2 bodies. Problem: I have too many problems with my gas kiln for cone 06 anymore. I'm DONE. I am moving to cone 5. Criteria / Factors: I'm in Southern California I teach 180 high school students grades 9-12, all levels of art skills, so it has to take punishment Not too sandy on the wheel, not too smooth or squishy for hand building Not too dense so it is so top-heavy wh
