  1. I have no neighbor close enough to be bothered by the fumes. this window is on the second floor and the third floor is mine as well. opposite the street is too far away to be bothered by fumes. as for the landlord, yes I'll be checking with him. I dont really want to fire luster at home anyway, it freaks me out too much. so you really think a regular fan would be enough ?? thanks for the reply !
  2. I just moved in a new apartment and I'd like to use the extra space as my studio. there is a small den on the left of the staircase leading to the bedrooms upstairs, on the right of the staircase is the living room/kitchen. (check the picture attached) there is no door to close the den, not sure if I would be an issue... I could set up a heavy curtain if needed. so I'm planning on putting my Paragon Xpress-1193 in the space under the staircase that has the brick wall. now which kind of vent should I go for ? I mainly want to use the vent to exhaust all the fumes during bisque and glaze firing. I also do luster but would it be safe enough to have a vent in a space that is open ? would a heavy curtain closing the space do the trick to be sure no fumes goes in the living area ? on the paragon website they seem to recommend the KILNVENT MASTER 120, should I go with that or with a hood vent ? thanks for you help in advance !
  3. I've been working on the molds of my sake set for the past week and I'm still not done. this is really time consuming and a bit frustrating for me (as I tend to be an outer perfectionist). I would like to find a professional mold maker, that would save me some sanity haha. is there any pro mold maker here ? or do you have any to recommend ? thanks in advance!
  4. I did add a layer to the silver cup. the cup I try to burn off the luster from was another test, I only wanted to burn it off because some of the luster went on the top where I dont want any... I thought I cleaned everything but the glaze being black it's very hard to see if there is any luster where I don't want it. next time I will use a luster eraser if I can find one at my ceramic shop. thanks for your answers Johanna !
  5. is it normal for a high fire glaze to change so much at 06 ? I fired it a cone 6 I'm really surprised it had so much effect on it...
  6. I did my first luster tests a few days ago. I actually fired them twice to retouch them a little... I might fire again because the silver one is not fully covered at the bottom.. or I'll just try to make new tests and learn how to handle lusters more. the gold is a bit cloudy at the bottom... I messed one of my test cups and got luster on the top, I was sure I cleaned everything though, but I guess doing luster on black glaze makes it harder to clean up... I'm using Duncan lusters and they say to fire at cone 06 to get the luster off, but that didn't work for me, the gold luster only partly disappeared and the black glaze turned bubbly and cloudy any tip on firing off luster without messing the glaze ??
  7. love instagram! http://instagram.com/dontstareatthesun
  8. thanks everyone for the replies! you've been very helpful! I'm not going to use this glaze then, because I really don't want to take the risk to have copper leaching
  9. ok I see, not worth it then I just really like a low fire glaze I've found (food safe) and don't seem to be able to find something similar in high fire glazes it's the Amaco Opalescent Black Tulip http://www.dickblick.com/products/amaco-opalescent-glazes/ I could try to fire it at cone 5/6 and see how it looks but then I wonder if it will still be food safe...
  10. is it food safe to use a low fire glaze (05) on a porcelain piece bisqued at 04 ?
  11. in the book I have it says "soaking porcelain for 1 hour will burn out any organic materials that could cause pinholing and other glaze faults" it also recommends 15-20 mn soak for low fire
  12. so I recently purchased a small 120V kiln to use outside (I have no space inside unfortunately, but I do store it inside when it's not in use) it's the Paragon XPRESS 1193, chamber 11x9 in, 0.56 cu ft http://www.paragonweb.com/XPRESS-1193.cfm it comes with the Sentry Xpress 4.0 Digital 3-Key Controller. I'm a real beginner at ceramics. I did the first firing yesterday at cone 01 with the lid open a few inches for 1 hour as recommended, peephole open and the shelves inside. today I'm doing my first bisque firing. I've read the instructions many times and all I could find online, but I still don't know a few things... it seems that I should vent the kiln in the first stages of the firing, I proped the lid open a few inches and left the peephole open but I'm not sure how long I'm supposed to leave it open. the pieces are really dry (casts that have been sitting on my shelves for weeks). so I figure I would check with a mirror if any steam would come out from the peephole and close the lid around 200°. I saw no steam forming on the mirror at all so I actually closed the lid 25 mn after starting the slow cone 04 program. the temp was about 160° i think. should I have left the lip open longer ? I'm really unsure of the venting time required. I've read that the slow program is recommended for bisque. what are the risks and advantages of doing medium/regular and fast speed ? also, what should be the soaking time ? I've read in a book that porcelain should soak 1 hour. for this first bisque firing I have both porcelain and low fire casts, so I programmed the soaking time for 30mn. should I increase it to 1 hour ? also, I've read you should always leave the top peephole open, and well, this is a small kiln so there is only 1 peephole. so I'm not plugging it. when should I ever plug it ? the instruction manual is not really clear... in a few days I'm going to do a glaze firing at cone 5 or 6 for the porcelain pieces and a glaze firing at cone 06 for the low firing. do I need to have a venting time at the beginning as well ? if so, how long or at what temp should I close the lid ? I guess I should leave the peephole open during the glaze firing as well. what about the soaking time ? what should it be ? again, what are the advantage and disadvantages of doing slow, medium or fast program during a glaze firing. any recommendation? I'm sorry I'm having so many questions but I find many different instructions online and I'm not sure what apply to a small kiln like mine. any help is welcome !
  13. all your posts are really helpful and I've decided to buy a small test kiln to use outside and store inside when not it use thank you all !
  14. yes I guess I could store the kiln in the kitchen after use... to be clear, using a kiln in an open space where you work is a big no-no, right ?
  15. Hi there, I'm a real newbie to ceramics, I just finished my first project, a black porcelain sake set: http://www.dontstareatthesun.com/work/yozakura/ and I'm going to start working on new projects, so I'm thinking of investing in a kiln. but! I do not have a basement nor an extra room I could use. I was thinking of getting a small test kiln to put in my kitchen (which has no door and is open to the living room where I work most of the time) but I've been told it would not safe. now, I do have a backyard, would it be possible to have a kiln outside ? I searched this forum and googled in order to find some answers, it seems some people do it but I still don't know if it's ok to do that. I mean, would it be ok when it snows and rains ? what about when it's super hot during the summer ? would the changes of temperature outside the kiln be an issue ? I don't even know if my landlord would be okay for me to have a kiln outside but before I ask him I want to make sure it would actually be an option. thanks for reading!
  16. I just dont understand the logic... yes 1lb is 16 oz, but I don't understand the maths here 6 % of 10lb is about 10z and 8% of 10lb is 13 oz so your math is right even if I don't get it haha I just found out this page: http://shop.clay-planet.com/stains.aspx it says "Black, being total color saturation, requires at least a 10% addition, usually higher to avoid grey" have you tried 10% ? do you think it's too much from your own experience ?
