SC2 overfire and burnt inside

[Dragonfire Glass]

I would do another test firing, but I think the plug in or out is immaterial. You will be using the plug in for annealing.
It will help you get used to the kiln if nothing else

Thanks for that advice Colette. Yes, I think I will be happier when I'm more familiar with using my kiln. I'm desperate to put some glass in there though!

All the best

you might find that some of the internal staining burns away over time, when I used silver clay i got a stain, but its not there now...I have some brown marks on the door, but it just looks rugged...who wants a kiln that looks like its never been used anyway

[Shirley]

I think the idea of having the plug out is so that whatever it was that stained the inside can escape. Best to have a window open too.

Thanks for the reassurance girls.

Well, I've just set it to run again without the plug in (and with the window open) at the 3rd speed, 555 degrees C per hr, and then to hold at this temp for 10 mins. If it all goes according to plan, I shall try another empty run to a much higher temp. I'm feeling a bit less stressed about turning it on this time

Lets hope it all works this time.

Thanks again to everyone for such great help.

Thanks everyone for such great reassurance and wonderful help over the last day or so.

I opened my kiln this morning to find that it was all beautifully white inside again. even the inside of the bead door was white again and I'm feeling a lot more confident using it now. The program ran according to plan.

Do you think I need to do another empty run at higher temps before putting anything in, or should it be OK now?

Thanks loads. This is such a helpful forum.

All the best

I think you should be ok now. Have fun, and make sure you show the results

[flowerjasper]

glad its all ok now, i worried sooo much about my kiln, now i wonder why 
the advice here is from experience and trial and error!   always ask as there are some very talented people here who are always willing to share,

bless you - you must have got a fright and a half!! it does sayto do an empty run and to vent (but for a complete novice it doesn't fully explain what this is!) I needed a real idiots guide!

[sea-thistle]

I had a look in our SC2 instructions last night but couldn't find anything! glad your kiln is working ok. I've had mine about 4-5 years On the inside cover of my instruction book on the digital controller on the SC2, it has firing temperature conversion tables with Fahrenheit and Celsius. Maybe you have one in yours

[theseahorse]

I have to say, I did get a bit of a fright and wondered if I'd get the courage to turn it on again.

I think I do need an idiot's guide. I've read the instructions twice now and I still can't find anything about doing an empty firing 1st. I'm very grateful for this forum.

Thanks Sea-thistle for the tip about temperature conversion tables. Unfortunately, my version of the SC2 didgital controller instructions doesn't seem to have this, but I have been recommended in another thread in the fusing section a link to look at.

I'll try and post what comes out of my kiln. Do people post disasters on here too?

Thanks everyone

love

you can google conversions of all sorts 

[Zeldazog]

Just remember if you use conversion tables that there are different ones for TEMPERATURE and RATE. 

(so 500 degrees F converts to 260 C, but 500 F per hour converts to 278 C)

I am not sure how different the two are, but they are!

Already posted on another thread, but I have this page bookmarked for whenever I might need to check something:

Can you change the output reading on your controller - I have a Skutt, which came in Fahrenheit, but I was able to change it to Centigrade (useful for slumping and fusing programs that I know in my head, but not so good when I want to try a program from a US site!)

[Dragonfire Glass]

my SC2 has the choice of either

I'll try and post what comes out of my kiln. Do people post disasters on here too?

Yes and works in progress too because other people might help in diagnosing where I am going wrong when attempting something different.
