Life is a continuing learning lab, isn’t it? Thanks for sharing your victories and defeats…
I bought a Skutt j ust like yours about 3 years ago and I'd swear we're mirroring each other and our lessons. One is taught to throw pots on the thinner side and not unlike yourself I opened my kiln and found pots twisted and warped. My skutt fires on the hot side and I've learned to fire it at cone 4 with a 30 minute soak and now my witness cone 6's are bending just right. I had an explosion in mine too, damnit that pitcher was a beauty!! LOLOL So hey Lady... Thanks for sharing your process as I do enjoy watching your videos . You've got a sister potter in Denver Colorado that feels your pain and smiles with you at your keepers!!!
Thankyou. I agree the Skutt is hot. So I’m now using the preset cone 6 with no hold and accepting it’s a 6 and a half. Because no pinholes and glaze is always good. So not going to change it just yet.
Glad to see a video of what can go wrong rather than just happy results , Thank you
I’ve had pots explode and it’s very frustrating. It taught me patience. Love your videos. Thanks for sharing.
Lois, I know its frustrating but I really appreciate that your being vulnerable on the good days and the bad. It is educational, Im just sorry it is at your expense, lol. I just had a conversation with the Lady who first gave me pottery lessons about my plates warping. She said I was throwing to thin and be sure i am drying them very slowly and evenly.
I like your bowls with the brushed swoosh. So many heartbreakers, though!
Oh dear. I make a cone pack of three with the target cone in the middle. I make coils of my clay and then place the cones at the correct angle into the clay. Then I stab the heck out of these little clay sausages with a pin tool. I was taught to work in a bit of vermiculite into the clay used for the cone pack to help with drying and to prevent them from going kaboom lol! The cones used to come packaged in vermiculite, very convenient Now I just make sure that there are a lot of holes and that they are very dry. I often do a preheat to make sure things are dry. If your using a porcelain style of stoneware too thin to hot is the perfect combination for slumping. I make my plates much thicker with a deeper foot and a rim on more of an angle. Your glaze combinations are excellent. I love watching your openings. 🇨🇦
Thankyou so much for the advice. And putting pen to pepper. Really appreciated.
Ohh, I know the feeling of frustration when you open a kiln and so much has gone wrong. I've had a more than half kiln of blistering pieces once when the kiln overfired. I love the glaze combinations you've got there. As we know, there's nothing a given thing in pottery. Thanks for sharing and keep up the good work!!!
Hello from New Mexico, I just bought a pint of Vintage Gold and I have been searching for someone's firing of it. Our kiln runs hot so I may fire at cone 5. Love your videos! I tell my girlfriend that ceramics is learning and perfecting constantly. I am grateful for content creators like you that share their experiences.
I really like watching your glaze videos. Extremely helpful and saves countless people time. Really like your amaco sandstone with lavender mist. 14.40 ish in your video.
Oops sorry meant it was 1423 in the video
Thanks Jason. They are the Mayco glazes. Thanks for your message.
Like seeing/hearing about the results of your efforts even when they're of the unexpected variety. Watching each piece come out of the kiln is more interesting for having seen the steps that lead up to their final form. Thanks for sharing your progress with us.
wow what a shame. I'm so sorry for the explosion. Thanks for sharing
Can't win em all.....and I know you've learned a ton. Very valuable kiln! ❤
Well what a great bunch of learning how wonderful!!
Our community kiln, fires to Cone 5 with a 30 minute hold and natural cool, and it comes to a cone 6, and we no longer get pin holes. Ancient Copper turns out beautifully, if we give it space around the piece.
I feel so bad for you. I’m so sorry this happened.
Thanks for sharing it is not a mistake more of an learning opportunity for you and me
I feel your pain a few weeks back I had virtually the same kiln unloading, my cone pack exploded and wrecked pretty much everything else ( I think mine exploded because it was too thick and possible y not completely dry in the centre perhaps). I make a lot of platters and never had any trouble with them til I tried sitting them on the large cookies ( something I saw someone else do and decided to try) which caused the base of them to push right up making them useless ... so frustrating to say the least. I also use to glaze fire at Cone 6 with a 10 min hold but dropped down to 5 with a 10 min hold and was much happier with the glaze results ( I use mostly amaco and some of the mayco glazes). I absolutely loved the bowl with sandstone and lavender mist ... beautiful :)
Thanks. Really appreciate you taking the time to out pen to paper. Everything you’ve said just reinforces my thoughts. Thanks again.
Thank you for sharing this video with us so we can all learn. Even though this load was disappointing for you, your other work has been beautiful. I'm glad I stumbled across your channel.
Thankyou.
@@LoisHook i sent u a list of these one's I'd like.. Don't dust bin them..luv
Bless your heart. This is why my studio is overflowing with bisqued pieces. I'm just not brave enough...
ARGH!!! the science behind the art!
ahhhhhhhhhh! But I love your attitude through it all. Thank you for your videos!
Hi Lois. oh I feel for you, soooo much work goes into that kiln load. It feels disheartening but once you've taken a step back and seen all the lessons learnt in that kiln, it turns it into a positive. We learn from when things go wrong. I'm still struggling with things warping too. Great video and thank you for sharing it. We all felt it with you I'm sure. You're doing amazing work.
I like the oatmeal over snow. Love your glaze storage!
If your plate is B Mix 5, that would explain the slumping.
Thank you for sharing. Enjoying it.
In the UK. What’s a bmix 5. No grog??
@@LoisHook a white stoneware sold by Laguna.
Bummer what happened because the glazes were so pretty. I really like the impressions you put into the bowls and how the glaze flows around them.
Great stuff! Love the lavender and winter wood. Sympathy for your exploding cones. ☹️
Never have any luck with the mending of cracks. So far mine all reappear in glaze and get bigger. They do just fine in bisque. I use half shelves and alternate their height. Often load as close as three inches apart with plates all the way up except for a scattered shelf or two of five inch mugs. Fire to cone six with a ten minute hold all the time. If you make plates expect the rim to fall about 1/2” in firing per Matthew the potter. I throw thin too. Really love your colors!
I’ve had the same warping problem with most of my plates...I followed Simon Leach’s plate throwing process and have my fingers crossed...hope to fire today. My plates, I feel, we’re too thin before I tried Simon’s instruction. I don’t glaze the bottom, of course, and place the plate directly on the shelf...without a cookie. I’ll post the result. Love your colors and combinations 👍💁🏻♀️🌻🌻
Thankyou I look forward to it. Good luck.
Ah such a sickener. I’ve just emptied my kiln and found pinholing on all things on top two shelves. Better luck in the future 🤞🏼
Sorry for the cone mess-up ; live and learn:)
Thank you much fir your share😊
Sad that you had this happen. The blue bowl on the top of the kiln is beautiful other than the exploded clay.
Hi, Lois. The crystals in the Mayco glazes love to stick to the bottom of the tub. Shaking it is not enough the first go around. You'll need to mix it with a spoon and get the crystal off the bottom. Hope this helps you with the Aurora Green.
I appreciate you sharing your challenges with this firing. It helps us learn from your experience. The glaze combos were wonderful. I think plates are hard to get right, too thick and they carjack, too thin and they warp.
Such a same about the cone explosion, but great video to learn from.
My fav combos are:
Sandstone/ lavender mist
Sandstone / Aurora Green
Midnight blue
Sandstone/ midnight rain
I’ve made my first plates so I shall use your video for reference, wish me luck :-)
Duh, refire those, I have and some have even turned out better the 4th round of firing LOL I swear! And I have to make my pots a little thicker also which helped a lot!! Good luck!
I'm sorry you had so many oopsies :( You do awesome glaze jobs and I love how you share your application and results with us! Every 10 minutes of a hold will add about 1/2 a cone of heatwork to your kiln. I fire to cone 6 as well. To achieve this in my kiln, I set it to a cone 5, medium-slow speed, 12 minute hold. I had to play with hold times to get the cone bend I was happy with. My kiln runs hot naturally. I would suggest you try setting yours to cone 5, medium-slow speed, then play with hold times from 10 to 15 minutes. You should have better luck with a cone 6 bend on your witness cones this way. Good luck and keep up the awesome work!
That really helps. I just re fired to cone 5 with a 10 minute hold and it was a cone 5 the 6 didn’t bend at all.
I will have a play. It all started me doing. Cone 6 with hold because of Amaco ancient copper which I get lively that that bit clearly had issues this time.
Maybe you can try to ground the cones out from the pieces and refire the pieces, but put on the cookies, the glaze maybe run on the second fire. Good luck and don’t be upset, S happens 🤗
That’s exactly what I’ve done and added some more glaze in the bottoms. Only on the inside. May be too much glaze. We will see.
Also you can make a bunch of cones and let them dry and when you are ready to fire just get a set and put on the shelf, usually I make a dozen of them and leave them together with my posts 🤗
When we make cone packs a few tricks. 1: make it in descending order and where the lowest cone will bend down make a spoon-like depression. This ensures if you put the wrong cone in or a run-away kiln the cone won’t puddle on your kiln shelf. 2: use a cone to poke little depressions into the clay of the cone pack. Your clay will dry faster and won’t be too thick. 3: make a ‘clay god’. Each kiln needs a minor deity to watch over it and bring good luck. : ) CHEERS
Hi Lois, I got the same result with Aurora Green first time round. Now with any of the crystal glazes I shake well and decant a small amount into a dish and brush on from there. It allows you to ensure there is a good distribution of crystals.
Thanks Tammy. There were never any Chrystal a in the bottom so non in there. Get your idea about take some out when dispersed though.
Re Fire is on. !! Watch this space. !!
Alumina hydrate I believe is what you need underneath plate to aloe for movement due to shrinkage
I have Aurora Green also and it always comes out looking just as your test bowl. Maybe once it had a few more speckles/bursts, but not much. Good to see that I’m not the only one. 😉
I also have aurora green but forget to use it. I did get a replacement tub as first tub had no blue Chrystals to make the reaction.
Sorry things didn't work out in this load, I have a memory of a load that was disappointing also.
😳 I think you handled it better than I did. 😁
Ya unfortunately I think it fired too hot and as far as throwing too thin , I think your throwing is beautiful!
you are handeling this experience with grace ;) Have You got grog inYour clay?
Interesting Question. The clay used for the cones was high grog and a Raku clay. The rest are ES10 no grog.
I had a whole bunch of pitting… made a call to the glaze company… You might already be doing this…BUT, They said bring it up slow, real slow ... did it 👍🏻it all flattened !
Cheers to learning! Re fire the batch 🤷🏼♀️ will all the bits melt ? I’m new to the pottery world TOO! Really enjoy your videos(: thanks
I’ve ground the bits of with a dremmal then added some more glaze in the bowl and will re fire later today.
@@LoisHook look forward to the results! Your info is valuable stuff! Thank you!
The blistered ones you can refire I've got good results after refiring. Pinholes sometimes dissapear, sometimes not. Try the Camille Hoffmann firing scedule, it's available for cone 5 and cone 6 firing. I've never got any pinholes since I use it.
Never had pin holes before. I am re-firing later today. To a cone 5 with a 10 minute hold. I will put the Vintage gold back in.
I know how you feel. I've had overfires in the past. Heart drops. Is your kiln electronic or is there a cone sitter? I hope you never go through this again.
Lol and one more time cause I’m dumb, these are amaco or matco? Thought they are amaco but couldn’t find sandstone or lavender mist on their site.
Sandstone and Lavendr Mist is Marco. I bought them to try as they are colours Jon the potter uses.
Me again sorry, I should watched till the end😀 take the hold out, maybe you get just cone 6, the hold makes hotter 🤗. Just a suggestion 🤗
Yes your right. At the beginning no hold. Then followed everyone’s advice and it’s been too hot ever since. Re fire cone 5 today.
Good luck 🤗 let us know if works
Does anyone know what causes glazes to "skip" or "slide". I sometimes get bare spots where the glaze seems to slide down the wall during firing.
Hi, I am not totally sure. I had it once where I had layered and then I felt the kiln was hotter than the glaze really likes and it had slipped in a few areas. Also make sure the pot doesn’t get any grease or dirty hands as you paint in as that can affect the way it is absorbed. Sorry I don’t totally I’ve the answer for you as I am still learning.
Don’t pretend to understand the technicals, such a shame that you had issues. Some of those colours are amazing. As you say lots of learning, but a great job non the less
Paisano's Roost Farm (American Blackbelly Sheep) in Southern New Mexico: You might want to check out JonthePotter's youtube channel to see what he uses in his kiln. He uses the some of the same glazes.
Thanks. I have been watching jon the potter since I started and he is one of the reasons why I bought a Skutt. The Mayco glazes was me copying his suggestions and the test pieces was because I could not work out the beat way he glazes them as he uses dipping glazes.
Thanks for the info though it’s great to hear from people.
Hi there. Someone else may have already mentioned this to you (can't read the 40 comments before mine). Just wanted to help with the Mayco crystal glazes, such as Aurora Green. All the crystals settle to the bottom of the jar. You need to take a spoon or a chopstick and really scrape the bottom of the jar really well as you are stirring. This disperses all those crystals into the glaze. They can keep settling if you are glazing many pots at once, so just give it a stir to bring them back up. You can even pick them off the pot and put them where you want them, if you have too many clustered together. Mayco's youtube page has a great video, www.sharonhoppedesigns.com/shop/sharon-hoppe-designs Hope this helps you!
Thanks. I didn’t het any even in the bottom before I started to mix it up. That’s why I need to speak with the company I bough it from. Thanks for all the info I really appreciate it.
