I'm trying to create a excel spreadsheet which will tell me roughly how long a programme will take in my kiln.
I know that it is probably extreamly variable due to different condidtions but does anyone have an idea of an approximate rate that a kiln will cool down when the programme has finished. Or a way that I can calculate it. Is it going to be different on each and every firing? or will it matter how high the kiln is when the programme is done?
I would be more than happy with an approximation...
depends on ambient an the kiln.. the bluebird cools naturally at over 100 deg / hour here.. although our internal temp in the barn is only 5 degrees... the xl, which is fire brick lined, cools at less than 40 degree's per hour in the same condition (and should be about the same for an sc2/3, although the sc's with bead doors have a small opening when the door flap is slightly raised... the sc2 cools down slightly faster than the sc3...
Thanks hunny!!! xxxxx
Thats exactly what i needed!
Now - thanks to my wizzy spreadsheet I know that my pot melt thingy will be ready to come out at about 9:00pm give or take 30 mins or so
Very clever!

I only have a little kiln so its just a tiny tiny one... it should come out as about 1" in diameter.... i thought that might be a nice size to put a bail on the back of
yay pot melt pot melt, pics please, from every angle and then a few more and how you did it and what you think of it and how hard you found it :D :D :D
Well I can tell you now that I used a egg poacher and some mesh you use to fix rusted out old cars... it soooooo professional! ;D
OK - there will be no pictures and we shall never mention the pot melt fiassco again.... :'(
Oh no! I was really looking forward to finding out what a pot melt is as well! What is it ???
Why, what happened, Stacy? You can't leave us hanging on like that!
errrrr.... it melted..... along with the egg poacher and mesh thingy that I rigged up
Its all one sort of metal and glass blob....in the future when I am a world renowed glass artist I think I will call this my industrial era.
Going to have another go at the end of the week when I have rigged up something a little more unmeltable!

Its when you put a load of glass ontop of a wire mesh or pot with holes in it. You pop it in the kiln and the glass melts through the holes into a puddle on the kiln shelf - you put lots of different colours in and they all swirl together.
Well that was my interpretation anyway - but we know how that ended! ;D
Oooh-that sounds really exciting! (I still think you should show us some pictures ;D)
I read you can do it with a terracotta plant pot - you can get those tiny ones and drill holes in the bottom - have seen the mesh ones too - what a shame Stacy!
I really want to try one of these, gonna have to raid a college or uni kiln, methinks.........
wow, that's fantastic!! Never heard of a pot melt, but it sounds delicious. Might have to try that some day!! Sorry that it all melted together, Stacy!

Ohh I've got one of those - Gonna have to give that a go today or tomorrow! thanks Dawn!
A "shelf melt" is when you pile up glass on the kiln shelf and fire it to all melt together.
A "pot melt" is when you suspend a pot (like a flower pot) over the kiln shelf and let the molten glass run out through the hole in the pot.
A "screen melt" is when you suspend screen over the kiln shelf and let the molten glass melt through the screen. Here's some examples of screen melts.
