In this video I'm talking all about single firing/raw glazing your pottery! Or - glazing pots in the "green" stage and skipping the bisque. I've always been interested in single firing and I couldn't find a lot of videos about it - so I made my own! This was a first for me and the results are exciting. I can't wait to take this further and explore some more. I know Lucie Rie was a real pioneer for single firing and an inspiration to me. Feel free to comment and give any further info or add anything I might not have covered! :) As always, thanks for watching!

A good way to minimize the dust is to get a 20" box fan and bungee a furnace filter to the intake side. It works better if you take five 20" filters and tape them together into a 5 sided box then have the fan blowing out from the 6th side to maximize surface area of the filters and get a good flow (there's plans on line for this one). Doesn't end the problem of dust but it does help pull ultra fine particles out of the air. I'm working on the once fire method myself, thanks for experimenting.

this is super helpful! thank you. we had awful wildfires in portland a few years back and did something similar. i’ll have to give it a go for the silica dust! :)

you have such a peaceful demeanor and this style of video is my favorite! I'm so new to pottery so this single firing is something I've never considered, does it affect the integrity of the piece?
@bwpottery
@bwpottery Жыл бұрын
thank you!! :) and not at all! the pieces are still strong and fully functional. i think the biggest difference/issue is that the green ware doesn’t absorb glaze as well as bisque. 😬

Just watched this for the first time, thank you! I'm about to embark on my first single firing. I'm intrigued with you putting the bungs in right at the beginning, I would've thought for single firings, allowing moisture to escape initially is key. It doesn't seem to have affected your firing at all. Was the kiln vented at all in the first couple of hours? btw I"m so impressed with your calmness at looking at the results! All those top pots would've been whipped straight out if it were me so I could see other shelves immediately! 😂

Thanks so much for sharing your experiment in raw glazing. I have a quick question: after you glazed the inside, you sprayed water on the outside to equalize the absorption. Do you do the same thing later on when you glaze the outside of the same piece (i.e. do you spray the inside with water after glazing the outside)? I'm considering trying raw glazing and I haven't been able to find a good answer to this question. It seems like it wouldn't be a good idea to spray water on a surface that has already been glazed but I'm wondering why it's necessary with one but not the other. Thanks in advance!

I think you are correct. It makes sense. I will soon be starting raw glazing at the studio I go to. I am a bit nervous.

If you made a denser glaze and altered the viscosity with darvan, could you theoretically go for a full dip rather than pouring inside/outside 12 hours apart?

This is video is so informative. Thank you so much! I have one question that came out of it tho :) If I can't assure vitirification of the ceramic, than it can't be defined as food sface right? To give an ilustration: I just bought an old kiln (those ones where it only shuts when the cone melts to its temperature). If I have a cone that melts at 1196ºC degrees and use it to fire stoneware clay that vitrificates at 1200ºC degrees, there is a difference of 4ºC degrees. I can't say that those ceramic works are food safe. Right? This having in mind the single fire method. Sorry, your video was so detailed and informative, but I still have this question. TSMIA!!

thank you!! and thanks for the question. i’ve had kilns in the past with a kiln sitter and they do make it a little bit harder! my best advice would be buying a pyrometer. put it in one of the peep holes so you can gauge the temp when it’s reaching top temperature. you can be there before the kiln shuts off (the lever drops) and catch the lever before it hits the switch. keeping the kiln on for a little longer until it reaches your desired temperature! 😊

A good vitrification test is to boil the finished glazed pot in hot water for a few hours then compare the weight difference before and after absorbing the water. Vitrified Stoneware should not absorb more than 2% of it's total weight.

Cant you just let it dry for longer (after glazing) ...then fire? The biggest for me would be knocking off time to get too that finished product/piece! Nice detailed tutorial..liked the ride!

Doesn't the temperature that you need for fire a bisque different than the glaze ? I haven't learn much about glaze yet, but I thought that was the point for why you can't glaze the bone dry pots without fire them. (since technically they still can absorb water)

it is! a bisque firing is around 1800 f where a glaze firing is 2250. a bisque makes the pots more durable but still porous enough to except a coating of water/glaze. a pot that is green, or not bisque is also porous and will except glaze/water. :)

oh no!!! honestly my worst nightmare. after some more experimenting i sort of stick with a bisque before glazing. i just don’t have time to reformulate my glazes to get the right thickness for single fire. bisque pots absorb the glaze so much better than bone dry pots. 😬
