Thanks very much
-
Thanks Bill. Yes I am firing to cone 8
-
Thanks Min, I’ll try fix the pin holes (potentially too thick and glaze recipe issue) first but the drop and hold sounds like next step if I can’t get ontop of the pineholes. with regards to increasing the second ramp, is this likely to alter the appearance of any glazes or cause any blistering etc? I’m quite new to using my own programmes rather than using the standard presets of the skutt kiln.

Thanks Bill. I previously tried top temp of 1230oC and it overfired quite a bit fully bending cone 9. Yes I use witness cones and this schedule gives me a perfect cone 8
-
Hi Min, firing schedule (Celsius) is 1) 90o per hr until 300oC. 2) 115o per hr until 1080c 3) 60o per hr until 1220oc with a 20min hold. Pin holes could have been caused by a glaze too thickly applied

Hi Jeff, thanks for your reply and details. All noted:) I’m not that happy with the firing, have experienced quite a few pinhole issues so wasn’t sure if the kiln got too hot and started creeping above cone 8 temperature.
-
Hi everyone, wondering if you could help please. Im still learning how to interpret witness cones and not sure if these have overfired past cone 8? (cones are from right to left :7,8,9 ) thanks so much, kathryn

Bisque firing issues still

I have tried using the pre programmed bisque firing and had similar issues with cones not bending. -
Bisque firing issues still
Gonepotty replied to Gonepotty's topic in Studio Operations and Making Work
It's a new kiln and only done 13 firings. (Skutt with touch screen controller). Program is in celcius Set 1 :80 degrees to 600 Set2: 100 degrees to 800 Set 3: 50 degrees to 1000 with 20min hold -
Hi all, wondering if anyone can help please. Bisque firing seems to not get to temp according to witness cones. Firing to 990/1000 celcius. Cone packs 07, 06, 05. Cone 07 only very minuscule bend- I mean hardly noticeable. Top peep left out until 600 celcius and then bunged in. No issues with glaze firing, reaching target temps perfectly and cones spot on. This is very frustrating as I think the bisque must have undefined due to glazed pots with new pinhole issues... Thanks for any tips/help

Potters plaster reclaim boards
Gonepotty replied to Gonepotty's topic in Studio Operations and Making Work
Thanks both:) Seems like I am on the right track . Thanks for the excellent tips! -
Can these be reused continuously or will they eventually stop absorbing the water from reclaim ? I have a few which I have made and wonder what do I do with these when they no longer fit for purpose? Also wondering if they should be thicker or thinner? Mine are currently 5cm deep and wonder if this is why they take sooo long to dry out I between reclaim batches. Thanks:)

Thanks so much
-
This would be really great Min- thanks!
-
Thanks so much for your help:) I actually have a broken kiln shelf so will definitely use this!
-
Thanks Min, I'm assuming the base of the plates need to be unglazed to allow resting on the posts of these plate setters?
-
Is there a more efficient way of glazing plates rather than 2 plates per shelf ? (Firing stoneware to approx 1240degress celcius, underneath of plate also glazed- except the foot) My kiln is quite large but can only fit 2 large dinner plates on a shelf and I only have 4 kiln shelves and 2 half shelves . Any tips would be greatly appreciated
-
Thank you so much for your help. I'm right at the very starting on mixing up glazes from scratch so have been thrown into the deep end of glaze chemistry which I am loving but equally lots to learn. Glazy.org has been amazing with recipes and community of potters all helping each other:)
-
thanks so much for your help. This is fantastic! I will test this out. Any pointers/youtube videos on how I could go about reformulating glazes as you have very kindly done? Im very new to creating glazes and this would be very useful.

Potash feldspar 34 Quartz 23 Calcium borate frit 14 China clay 13 Whiting 11 Dolomite 5 Can get Gillespie borate....
-
It was suggested I try low expansion frit or borax frit
-
Hi all, I have a Linda Bloomfield glaze book which with a shiny base recipe which calls for calcium borate frit.....this in no longer available in the UK. Wonder if you have any ideas of a substitution? thanks!
