  1. Hi Guys, I have a small test kiln from paragon that has one peep hole and no vent. Everyone that I have contacted says that small test kilns don't need to be vented, just prop the lid open for the first few hours of firing and then close it. I have not had any success with this. I tried keeping it propped open until it reaches 1400 degrees, however it never reaches that temperature probably because the heat is escaping. It's mainly affecting my red glazes right now, however all of my glazes come out very dark and the red ones look burnt and brown ALL the time. After doing a lot of r
  2. Hi! I was running a cone 5 glaze with my skutt electric kiln and forgot to turn on my enviro vent. When I realized it was already finished and at 500F. I have the KMT so was able to see a graph of the firing which looked fine, but it did fire in 4 hrs instead of the regular 13hrs. What problems could this cause ??? Could this hurt my kiln for future firings? Vent is on now and another fan in the studio cause it definitely smells. Thanks!
  3. Hi There, I have an e23T L&L kiln. I have 1/4" holes in the bottom of the kiln. There are 2. I've been having trouble with bloating and pin holes during glazing. A colleague suggested I might need to drill a couple of holes in the lid to help with the air circulation. I read in the L&L manual not to add more holes. How can I tell if I need more holes or not? Thanks!
  4. I have a space I would like to fire in. 11x11, with concrete block walls, with a wood ceiling. I have thought to cover the wood with concrete board. It's a walk out basement area, so it only has a door to vent it, does any one have anything creative to vent the heat out of this space. I can put a box fan in the door way, short of that, I'm interested in any ideas.
  5. Hi all, I'm in Montreal and am wondering if people have had success with air purifiers in the studio. We have an air vent connected to the window which we use for sanding and glaze mixing (and for the kiln of course), but I'm talking about general dust buildup and air quality. Our studio has about 20 members (kind of works like a gym but for ceramics) so it gets dusty really easily. Do plug-in air filters/purifiers work to help take harmful dust particles out of the air? If so, which models do you all recommend? Low wattage is best as our electrical wiring is pretty sketchy and the fuse tend
  6. Does anyone have preferences about the venting systems available (to Canadians)? I have not been able to find any reviews online. We currently have an Ortons on order to be installed on our new bisque kiln, but studio partners want to look at other options. It was only ordered today, so hopefully we can cancel the vent order if we change our minds within the next day or so. Any thoughts?
  7. Hi all, Looking for some help. Firing my kiln today, doing something new. Doing a programmed ramp and cool down. After 250 degrees I am ramping at 500 degrees an hour to 1978 degrees (farenhieght). My kiln vent is on and appears to be working properly. The only other difference is the kiln is loaded with three new glazes. I have thoroughly tested the glazes, just never done a load of just the new glazes. Firing to a top temp of 2225. Using a cone 6 red clay, same as usual. The problem, the studio smells, really strongly. It is a normal firing smell as in my previous place I fired in an
  8. I'd like to build my own downdraft vent, and would appreciate answers to a number of questions. I have a lot of questions, so don't feel obliged to answer all of them. Based on the manuals for the Orton Vent Master, L&L Vent-Sure and Skutt EnviroVent 2, the main components I will need are: Collection cup with adjustable opening that sits under the kiln A blower A flexible duct connecting the collection cup to the blower Besides figuring out the specs of these components, I need to be sure I can obtain these (preferably locally - I'm in South Africa, and shipping from the US is expensive.
  9. So, the envirovent was accidentally left off during a slow bisque fire. Obviously, the kiln atmosphere was not oxygen rich. Can the work be re-bisque fired to correct some of the potential problems?
  10. I just joined today so please go easy on me . . . I'm a fairly experienced student and I love cone 10 reduction. My only kiln firing education experience was very limited and over five years ago, at a well-equipped big city community college with huge kilns burning natural gas. I was a newbie just following precise instructions from the instructor, so I'm just about completely ignorant in practice. I am now 500 miles away on a small farm with the new-to-me 12 cubic ft updraft kiln all hooked up to my 250 gal propane tank. The kiln is 7 ft in height including the ~ 2' iron stand. There
  11. Three questions: (1) The manual (yes, actually read & referenced) for my L&L Easy Fire kiln, plus an Orton Tips sheet, say to have the vent (Vent Sure) running continuously throughout the firing. Both specify to NOT open any peep holes. OK...but then how do I see my witness cones? And if the answer is in front of my nose somewhere, please be gentle as you chuckle! (2) The instructions for upon firing completion say it is safe (and preferred, I gather) to turn off the kiln. It also says that the controller will continue to read out the temperature as it cools down. Well, once I
  12. I installed a skutt envirovent 2 several months ago to help deal with fumes when firing (especially wax resist). My studio is in my basement and as I've transitioned to being a full time potter, I'm firing 2 or 3 days a week. The fumes were definitely shortening my life. Lol Vent worked perfectly until about a week ago when I started noticing fumes again. And tonight the smell was so bad it woke me from a dead sleep to open all the windows (even though its snowing with 60mph wind). So, I'm sitting in my living room at 2am in a parka and bunny slippers hoping someone has some experien
  13. Setting up an Evenheat programmable 25x23" electric kiln in a basement room that is 15x20'. Questions: 1. Is it safe to vent to the garage, avoiding drilling through the foundation, and propping open a door to the outside? 2. Are fire retardant boards on the walls in the corner good enough or do we have to put plasterboard on the reat of the walls? 3. Will a fire alarm go off is we fire to Cone 6 and, if so, how far from the kiln should it go? Thanks
  14. Has anyone found a suitable replacement motor for Skutt's Envirovent 2? I realize Skutt sells replacements, but was hoping for something less expensive and easily swapped with the old motor. Thanks! Regards, No Draft
  15. Hi I Need to buy a new kiln, and i was offer to install an orton vent master. Is it a good thing, what will be the advantages? or disadvantages? Right now i have a bathroom fan installed with a huge round ducking over the kiln. Will the colors of glazes change? Thanks Sylvain
