- Following last week's glaze kiln video, this is how to load a top loader biqsue kiln. If you're a beginner potter with your first electric kiln, or you've been in the ceramics game for a little while but you've not fired a kiln before, this video is for you.

I love your process videos. I always learn something.
thank you for this vid. you have a gift!
Brilliant video! I’m just starting my own kiln journey though I’ve done loads of pottery in the past in a studio… where I learnt lots. But when it comes to it I’ve been very hesitant to actually start up my kiln (fumes? Ventilation? Electricity requirements! Protecting the kiln in various ways…🤔😬). I love the vibe of this video… shall watch all your work 🤩 Thank you for sharing your experience 🙏😘
Can't wait to see you glaze and load those lovely babies. 🤩
It was so stressful watching you load that lol!! Great video :)
"Kids are hectic, man" killed me :D :D :D Amazing video btw!
This is a fabulous video - thanks for the great information! I’ve been trying to figure out a bisque program for the old manual kiln I just got. I am very new to all of this and couldn’t find anything that had basic instructions for what temps and how long to bisque fire. I’ll try your program as a starting point and see how it goes. Thank you so much!!
Feel free to go slower - 65°c / h works well in the winter, but if you’re not sure if things are dry you can go as slow as 50°c. I also will sometimes slow the second ramp to 150°c/h too, especially as the elements age. Good luck!
Great vid, thank you. I love the terracotta pieces. And could that cracked plate be glaze fired as two pieces, the little one looked like a crescent 🌙
Your videos are so helpful. I have only just begun to scratch the surface of my pottery journey! Can i please ask- so you can put all types of clay (stoneware, porcelain, etc) together in a bisque fire?
Looking forward to seeing what you do for the glazing of these pieces.
Yes all can go in the same bisque! The glaze firing is where you need to separate the clay types
There's ways to fix cracks in greenware. People make stuff called magic water and spooze and some kind of stuff with toilet paper. I've never tried any of those myself so I can't comment, but I have put things into like a super-damp damp box and have managed to save a few cracked items in that way.
I'm sure you've already scrapped those amazing Picasso vases (😞), but maybe future items can be saved?
Great vid! Sorry your coil plate cracked. I have issues on my lowest shelf with flat things. I now only fire small things like mugs etc on that lowest shelf. I’m not sure exactly why, but it has something to do with fast temps, heat, mass, whatever but anyway, just a caution for you. I’m still trying to figure it out.
Very nice
Question- will ALL "cone" level clays turn to ceramic @ ~600 degrees F?
Also, THANK YOU for explaining the greenware/bisqueware part. I'm brand new to pottery and trying to figure out my next step on some pottery my wife and I made. I looked everywhere for the definitions of these commonly used terms and everyone is SO technical. Like, I dont need to know the chemistry formula for clay to understand what "bisque" firing is!! lol.
Maybe I missed it but I didnt catch what "cone" your greenware is. And from what I learned that's a VERY important part when turning pottery into ceramics. And 99% of youtube videos dont specify the cone level of the pottery they're using! Especially since I could take techniques and advise and destroy my pottery by heating it to incorrect temps.
Ty and looking forward to a response from someone that knows better than I (hopefully).
I'm glad that was of use - when I was editing I wasn't sure if I should cut that out!
Greenware is unfired clay, so isn't a cone. But the clay that I'm using is fired to cone 8-10, but these bisque instructions in this vid will apply to 99% of the clays that you'll be using in studio pottery.
Generally all pottery clay is bisque fired to 950-1000c (around 1800f), and that quartz inversion happens around 600c with pretty much all clays. There will be a slight difference in all clays due to different levels of organic materials etc.
Where you want to be aware of your cone temp is when you are glazing - if using an earthenware, it could melt or bloat if you put it in a stoneware firing. If using a stoneware clay, it will be underfired in a earthenware firing, for example.
Hope that helps!
Lob the accent. Reminds me of home. Interesting video thanks.
love it
I have terracotta clay(900°), and stoneware (1100°C). Can be they fired simultaneously? Also, do i need to clean my tools and wheel after each use to prevent one clay get into another? Or it's not really important
Can pieces like plates touch the side of the kiln when you stand them up?
Yes
That terracotta is such a nice colour!!! Is it waterproof in this stage, or is that why you then glaze it?
I love it! That's why it gets glazed - it's still a bit porous at this point. Terra cotta generally melts before it's able to become fully watertight!
Hi Mae, I was gifted about 200 doll parts moulds for porcelain slip casting. I need help firing. I want to make doll head pots for succulents. Problem is I need more advice on kiln temps to make porcelain clay hard. Where do you order your clays from? I noticed you have terracotta and white, do they fire at the same temp? Im so green. I did ceramics once when I was a kid, we had to clean greenware before bisque firing then glaze fired next. Id love to make a line of pots for ETSY. Im following you closely.
Hi! Sounds like you have a future dolls factory… spooky!
Porcelain slip can be fired very high, check with your supplier. I get my clays from Bath Potters or Potclays - if you’re in the uk check them out. Otherwise look up local pottery suppliers in your area - don’t go to amazon or similar as you’ll pay higher with no support.
Terra cotta and stoneware can be bique fired together, but the glaze is separate. Watch my glaze firing vid for more tips there :)
Hello, he is a pottery maker, can you give me advice?
Is it stoneware or earthenware clay?☺️
Mix of both! They can be fired in the same bisque firing, but glaze is separate.
so there is no way to repair greenware when it has cracks?
There are ways - but they very often will open up again in the kiln. generally I think it’s a good rule to remake the piece with the lessons learned sadly.

Hello, I have a simple question for you, unfortunately no one has ever been able to give me an agreement, what is the maximum mass I can load my 310L kiln with? do you know maybe?
Hi you sound Australian ❤

Too bad about the loud annoying music while you are talking. Doesn’t really help me learn or understand if I can’t hear what you’re saying. Just saying.
