    Question?? I am a new potter and I am using cone 5 and cone 6 stoneware clay and cone 5 & 6 glazes.
    Do I need to bisque fire at cone 5? I know the glaze firing needs to be at a cone 5 or 6. Appreciate your input. Thanks! TP

    • @OutpostPottery
      @OutpostPottery  8 месяцев назад

      Hi Tosha. You usually bisque fire much lower - like cone 04. I usually bisque at cone 010 or 09 (somewhere in the 1600F range). If you bisque fire all the way up to your peak temp (cone 5 or 6 in your case), your glaze will have a tough time adhering to your pots because the clay body is already vitrified - meaning all the tiny holes in the clay body have already closed up - not porous anymore. Does that make sense? Hope that helps - and it will save you some electricity / fuel as well :) -mj

      @OutpostPottery  2 года назад +1

      Hi Mary. Unfortunately, I don't have a lot of experience with kilns with sitters. I used one at the local community college but i don't have a ton of reps with that. If I'm not mistaken the time of firing will be dependent on when the kiln reaches the cone on the sitters peak temp - then it melts and makes the trigger/sitter auto shut off. I don't have the lingo down for this system becuase I dont use it but I believe the time of firing should be similar to my bisque firing time - somewhere in the 5 hour range if you're ramping up really fast and 8-10 hour range if yo're going really slow. I hope that helps. Sorry I don't have much more to offer there. Let me know how it goes!!! -mj

      @OutpostPottery  4 месяца назад

      you should be able to add slip or underglaze decoration at the bisque stage but I wouldn't try to attach anything functionally. I use underglaze / colored slip on bisque all the time.

    Thank you for your videos! I was wondering, how do I know if my pottery has been bisque fired if I dont have a temp gauge. I am doing more primitive type pottery with an adobe kiln I made and occasional pit fires. Also do you think it would be possible to glaze pottery in a wood fired brick kiln (currently trying to make one)? Thank you in advance!

    • @OutpostPottery
      @OutpostPottery  3 года назад +1

      Hey Higher perspective. Thanks for the question. Usually bisque firing is around cone 04 (1845 F) all the way down to cone 010 (1650 F). I think this is a lot higher than the traditional pit fire. Something called Quartz Inversion happens around the 1450 F mark as well - I heard that was important :)
      I don't think pit fires usually get hot enough for stoneware. When I think of pitfire i think of earthen ware clays - a different type of clay - more like terracotta. But perhaps there's another potter on this thread who can answer better than I can?
      You can wood fire and get all the way up to cone 10 (2400ish F) or even hotter. Some of the best potters do this. It takes a kiln especially made for this usually. Forgive me Higher Perspective if this is more basic than you're asking. I have a little experience with gas, soda and wood kilns but not much. I'm almost exclusively using electric in my garage. I also want to make am atmospheric kiln but not yet unfortunately :(
      Great question. Does that help? Sorry my knowledge is somewhat limited here.

    Hi!
    I am a new potter and super confused about how to fire.
    I have a cone 6 porcelain slip I’ve made mugs out of moulds.
    Do I still have to bisque fire this first? And then proceed to glazing and firing to cone 6?
    Or do I fire it to cone 6 from the start?
    I know silly question but I don’t have support where I am from :/ appreciate your help!

      No worries Catherine! You don't have to bisque fire first but I would. Some really amazing potters only do single firing, but i always bisque. It's easier on a number of levels, though it does add another step. Do you have a kiln (or have access to one)? -mj

      @@OutpostPottery I will be investing in my own kiln very soon. I have gone to a local ceramic shop but my mugs were refused since they said they only do low fire firings. Especially when I said they are cone 6 porcelain wet slip clay.
      For me the steps won’t matter once I have my own kiln. But I’m afraid of any explosions in the kiln due to inaccurate firing temps.

      @@catherinemontalvan4340 I bisque fire to cone 010. It's much lower but accomplishes everything i need in a bisque fire - makes it solid for me to handle, glaze, clean teh base, etc. It's a lot faster too since it doesn't go up near as high. Then I usually glaze fire to cone 5 or 6, much hotter. The main times i've seen explosions (rarely) are when students have really thick pieces in there or if the clay is still a little wet. As long as your walls hare super thick and your totally bone dry, you should be fine. I can't remember the last time i saw an explosion on my work to be honest. When i was starting out, i was under the impression that explosions happen much more frequently than they actually do. I would suggest you don't go too big. I got two smaller kilns for the price of one larger kiln and it has turned out to be a very good decision. Thanks for asking Catherine. Good luck!!! -mj

    Hi, thank you for the video but I was after a little more information other than stacking. It was great you mentioned drying out the pottery at 200Deg but was that C or F and what temp should you get it up too and for how long? do you need to exclude the oxygen? Are there any shapes that are harder to fire than others?

    • @OutpostPottery
      @OutpostPottery  Год назад

      Hi Tegan. 200 F was what I set my preheat to. When i preheat i usually allow 2 or 3 hours. It's actually longer than that because the clock wont start during the slow climb to the preheat temperature. The time you set only starts when it arrives at that desired temp - usually at least an hour to climb to that temp. No need to keep oxygen out of the kiln. in fact it's best if you leave the top cracked and plugs out while youre preheating. that moisture has to go somewhere and we want it out of that atmosphere inside the kiln. so go ahead and leave your kiln open a little bit. Plates are hard to fire... rather, they take a lot of shelf space. when you bisque fire you can stack them but be careful as they may warp or crack if you stack too many. I hope that helps Tegan! Don't give up - that's my best advice. Firing well is a skill worth investing in! - mj

    • @OutpostPottery
      @OutpostPottery  3 года назад

      Hey Michelle. I'm pretty sure you "fast glaze" which goes to 2167F cone 5 I think. I bought mine from American Ceramics in Fort Worth Texas and I beleive they advised me to put cones on the top middle and bottom shelves... then use the preset "fast glaze" button to run it. Then after it's finished and cooled down you can check out your cone packs to make sure top, middle and bottom are all firing evenly. Do you have test cones? Also, do you have a Bartlett controller - the box on the side of the kiln with all the buttons? Does yours look like this: www.theceramicshop.com/product/15013/bartlett-v6-cf-control-board/?gclid=CjwKCAjw_JuGBhBkEiwA1xmbRcrdj7jOSH3F9I7pcPSGt1jdncR9joFIvKZ47KiPlSdsbCT93pnLZRoCIsoQAvD_BwE?

    • @OutpostPottery
      @OutpostPottery  3 года назад +1

      Hey Bentley. I bisque fire to 1650 F, Cone 010 - which is 898 C... so we are almost identical in our bisque fire temps. most people i know bisque fire to cone 04 which is 1845 F / 1000 C. I only go to cone 010 because 1. it's faster and 2. saves energy/money but 3. still get's the vessels hard enough for me to handle them for glazing.
      No need to go higher in bisque but you do need to go the full peak temperature for the clay body you're using for your glaze firing. Every clay body (every type of clay) has a peak temperature. For me i use cone 5 or midrange clay from Armadillo Clay in Austin. It peak fires to 2167 - cone 5. That's the temp where all the little pores in your vessel get sealed up tight becuase of the heat. This is called vitrification. At the local community college here in town we used cone 10 clay. that means we had to take the kiln all the way up to cone 10 (around 2300 F / 1260 C).
      If you don't go all the way to peak temp for your clay body, your vessel may still have tiny pores in it (ie. its not yet vitrified). That might make it where it's not totally food safe or where it can't go in teh microwave. I'm not sure what else it means but that's my understanding of it. Hope that helps Bentley!

      @OutpostPottery  3 года назад

      Hi Kim. Good question. I like my olympic kilns. they have been really reliable for me. skutt kilns are really good - may people swear by them. they might be the "best" or priciest brand. paragon are good too but they seem to be... well i don't really know a whole lot about them except a lot of folks around Texas have them because they have a base in Dallas. I would recommend not getting one at first and just honing your skills. But once you have a good handle on the basics of throwing a good form, I would go with one that's big enough to handle the production volume you want to be at (you did say "yet" above :), but does not require you to change your electric box. I was thinking about a kiln that was 2x as big as mine - it was a slightly better value but i would have to spend a lot of money changing my electric panel so i opted for 2 of the same size and kind. it has proven to be a good decision. Thanks for asking!

    • @OutpostPottery
      @OutpostPottery  2 года назад

      Hey beautiful findings. sorry for the really late reply. the short answer is you firing schedules vary. If you are just going as fast as you can up to "peak temperature" - the temp your clay needs to fire to vitrify - then you can probably get up there in about 4 or 5 hours. Then, at the fastest, you can just shut the whole kiln off and wait for it to cool down. That will take about 12 hours or so. alternatively you can slow climb or slow cool on either end and add more time. Does that make sense? Sorry if that's a confusion answer. Let me know what other questions you have! -mj

    • @OutpostPottery
      @OutpostPottery  3 года назад

      Congratulations! Sorry i am just now responding. i"d love to hear how it went!
      in general you want the vessel "bone dry" as in no water. you don't want any water in there when you fire.
      I can be a bit impatient sometimes so i often preheat my kiln and let greenware dry out in a 200 degree kiln before firing but this can be hard on your kiln elements so be careful.
      basically, you want it completely dry. if you scrape or sand the surface dust will come off (but don't do that because you'll be putting silica into your breathing air :). Happy Firing Elizabeth!

      Most people bisque to cone 04 which i think is like 1845 F. But I bisque to cone 010 which i think is around 1650 F. I like bisquing to a lower temp because: 1. it's faster. 2. less energy. 3. it burns off all the organics 4. they say it goes through the Quartz inversion something are a lower temp than cone 010 so you're fine doing it. Honestly, I don't understand the quartz inversion but it sounded like it was important so I made sure teh temp was higher than the temp that would happen at. So i bisque to cone 010 - around 1650 F. Sorry - long answer to a short question ;)
