Yes they do have preloaded cone programmes so Im going to give that a go next.

If I do a cone offset will this only be effective if I fire using a preloaded cone programme? Don't think I want to offset thermocouple as my glaze firings are fine. I have a smaller kiln which has a S type thermocouple and its always spot on. - think i might consider upgrading mine when it comes to end of its life. Next bisque firing I'll try the preloaded cone 08 on medium speed as see how things go. Thanks so much for your help

Thanks for your reply. Not having any problems with the pots but rather feel that its not achieving the desired bisque of 950'C - trying to keep everything consistent so I know how the glazes will behave when applying and during the firing

Thanks for your message. I am going to try the preloaded cone 08 bisque firing next.

Thanks Neil, this was my next thing to try

Thanks Min, yes it only has 1 thermocouple. I'll make note of this info for my next bisque firing

Thanks so much Pres, super helpful information and great explanation. Feel more confident now with bisque firing

Thanks Babs, its really helpful to have many reference points/info from different folks as it helps build a bigger picture for me.

Thanks so much for your repl Thanks so much for your help. I think I'll adjust the firing schedule and make sure I pack it evenly! Really appreciate you taking your time to reply

Hi Pres, I used a programmable controller. Skutt 1027 with the new touch screen controller. Would you mind explaining how a tighter packed shelf will impact heat as this is something I am struggling to grasp. Thanks so much

Hi all, Having very frustrating results with my bisque firing . oxidation. Never seems to get to target temp...elements fine, glaze firing reaches target with no issues. Current 08 schedule ( Celcius) Step1) 80'C/hr to 200. Step2)120'C/hr to 915 Step3)60'C/hr to 995 +20min hold. (aiming for top target of approx 1015'C; kiln has always seemed to fire cooler for bisque by about 65'C hence aiming for this higher target in the hopes it will reach 950'C). RESULTS: Top shelf reached 08. Mid shelf reached 09. Bottom shelf … no bend to 09. Bottom shelf was densely packed...would this impact the firing.? Typically, my kiln is hottest on bottom shelf and coolest ontop. Was a ful kiln load with shelves and props. I have tried this below schedule in the past and worked quite well. It is listed as a "high bisque" schedule but wondering if it is too aggressive?: 1)90'C to 300 2) 110'C to 900 3) 60'C to 1050+ 20min hold. whilst I was quite happy with this programme, it fired a bit too hot for my bisque ware and reached 1000'C. I would like to aim for 950'C and so thought shall I: a) drop the final temp down to 1000'C+20min hold in the hope that it will reach 950'C? OR b) adjust the programme to the 08 schedule? Should bisque firings take longer than 10hrs? First firing schedule took 9.5hrs whilst the "high bisque" schedule takes 13.5hrs...Guess I was keen to also reduce firing time but it appears to not have worked that well. Any words of wisdom greatly appreciated!

Thanks everyone for your help

I have no idea…I don’t use terracotta so was going to use a pot from the garden centre

Would it work if I used a greenaware pot?

Hi all, need to make some calcined clay . Don’t have a bisqued vessel to put the EPK in…would an unglazed terracotta pot be alright?? Or any other ideas thanks so much, kathryn
