Well, theres not much i can add to this but oh bugger!
Testing the Janet De Boos glaze 29 again cone 03-02, this time i had a good bend at 02 in the middle of the kiln. So that’s the temperature right, and the fritt substitution was right according to supplier, but i’m not so sure…i imagined cream coffee was like a more opaque milky coffee?
Tested on the white stoneware, terracotta and the smooth white clay . Curious that the red copper oxide seemed to just coat the water and not absorb so skipped that one.
Now i just have to work out what’s what and do tests using a clear gloss base for #1, #2 and #3, and add an extra 4% iron oxide to the Janet de boos glaze #8,and maybe a lighter red iron oxide wash over #8, to see if i get a brown i like for the rumpots.
I have been loading the kiln for a bisque fire today, all done by 8pm. What are the standing Angels for The Domain Christmas Craft Market still doing over there!
Okay, so it isn’t all done, one more re-arrange of the kiln to make room for the Angels and it will be, did i really start loading at 11am 🙂
Caffeine or sleep …..hmmm?
Woops, they rolled into each other! A definite slumping fail but pretty in my window 🙂
Squeezing in a last minute firing in the kin before the market on Sunday, should be done by 2am. I’m on my second pot of strong tea and hanging in there, not long now.
The things we do for love aye!
Update: This is the one I will take tomorrow, the others got a bit too wonky, lesson learned 😉
Well…the glass seed beads were a disaster, were they even glass? They bloated, lost all colour and must have given off some kind of gas to make not so beautiful air bubbles. Will chalk that one up to experience.
Luckily I have just a few more empties, and on the shelf below 2 bottles fused together woops 🙂
Just switched off kiln and am letting the bottles cool naturally overnight.
One of my more nerve wracking experiments, but I am resisting the urge to think about the worst case scenario, just going to look forward to the morning when all will be revealed 😉
Morning update: I couldn’t resist a sneaky peek into the kiln just now, it’s still fairly hot so risked a bit of thermal shock but it was worth it, just had to see if it worked!
I like the way the glass slumped and didn’t melt, it has given me some new ideas.
The first cone is 016 and with the time of the firing and temperature reached it got to well over that, just wondering if the cone 015 is a little bit over done looking at the bend on the 014.
But I think it’s close and given a good starting point so happy :-).
The firing didn’t have a hold, but maybe being so well insulated had a similar effect by not letting the temperature drop too fast? Or was it choosing 800C to begin with was a bit high for cone 015? Or just that the kiln was empty?
Firing schedule was 1 for an hour, 2 for an hour, 3 for an hour and 20 min, then on full until top temperature, was a short firing.
My new baby is now connected, all of that hoping and nervous sweating, was worth it so far. I think my new lucky elephant key ring with its trunk in the air must have appeased the kiln gods 🙂
Today I am testing if the probe is reading correctly, so far all I know is it reads a temperature, but I don’t know how true it is. So this time I put 3 cones in 014, 015 and 016 set it to 800C and so I don’t waste the whole firing I also put a few pieces of glass in one of my terrarium pieces.
What I am hoping for is that the glass will slump into a nice little puddle inside the shell, which should happen at cone 015. I want to see a full bend on the 015 which should be about 800C, if the cone above or the cone below bends instead I should be able to tell if it is reading too high or too low.
If none of that happens I will be stuck and need another potters help!
At last the final stage of my latest creations, they have been on quite a journey and the ladies are still standing 🙂 I really like the depth of the glaze, the variation in tones, the result on texture and the accumulation of soda on the faces.
What do you think, feel free to leave me comment?
