Title: Be honest....at what temperature...
Post by: sparrow on March 26, 2010, 05:35:35 PM
....can't you wait any longer and grab your beads out of the cooling kiln?  ;D ;D

I normally put my kiln on over night so its well down to room temperature before its opened. but I think I would wait till its abut 35, 40c but that's just me being the cautious type.

:) I normally give up as soon as there's a 4 in front and it's double digits...although I've been known to open the door at 52 to speed it up :)

About 80-90, I pop them into something warm as well!
Mts only when I'm hanging about and not for big focals, usually I go out, come back and they are room temp - though it is hard to wait sometimes!

I anneal overnight so that I don't have to think about it!
I have been known to wake up at 4am and wonder what temp its at...but am usually too lazy to go and actually check

I used to take them out when the were under 40. Now my kilns outside and I also anneal over night so don't get to see them until the morning :)

I anneal overnight too but if I've had a really late session the kiln is often still at around 150 ... so I may just crack the door to speed things along.  I take them out when they're below about 90  :-[

we used to take blown glass out of the lehr anytime below 60, and if it was too slow getting down to temp we'd crack the lehr open at anything under 100 (altho only open about an inch) to cool it quicker so anything 70 or under and i will take beads out of the kiln

I've been know to whip em out at 100  ::) I figured my oven in the kitchen goes up to 240  ???

I usually wait til 50 now, just to be sure (but I used to be desperate and got them out at 100 (think the actual temperature of the beads was less than the read-out, to be honest).

Post by: Redhotsal on March 26, 2010, 11:03:13 PM
Um......about 200?  :o
But I put them in vermiculite......

Well, I'm old and I want to get to bed, dammit! ;)

Post by: Redhotsal on March 26, 2010, 11:04:24 PM
Anyway - once you've gone below the strain point it doesn't matter a jot unless the beads just crack because of the temp differential. It really won't make 'em stressy........!

Makes me stressy, flipping them from hand to hand

I'm with Sal, although I have kevlar fabric that I wrap things in and then hug them to me to stop any cold air getting to them!

If it's something in a mold then I wait till kiln gets down to 24 as the mold insulates the glass too.  I also don't coldwork anything or stick it in water for 24 hours.

I take them out any time below 100, but I don't put them in water before they're cool enough to touch.

I love the look of crackled glass its a shame its so weak
Title: Re: Be honest....at what temperature...
Post by: julieHB on March 27, 2010, 08:43:32 AM
I open the kiln door a touch as soon as the annealing session is finished, if I am there (about350 deg C to be sure), and at any point after that I whip out the beads and let them cool in the towel. Have never had a bead crack d/t thermal stress meeting with air at normal room temperature, although I probably would let a BIG bead cool off a bit more.  Does that make me the worst pupil in class...or just a very impatient one?  ;D

96 is my highest, but often below 90  8)

I overnight too, but I like em to be under 50c, and even then it stll hurts the fingers!  ;D

I usually do them overnight, but after a Monday morning session I get a bit impatient, wanting to have them out and off the mandrels before the school run. So I open the door at 300 or so and take them out once they get to double figures.

Post by: Cecilia on March 27, 2010, 11:32:56 PM
not sure really what the temperature is but i take the pot cone out of the top to speed things up a bit then if i am really impatient i get the welding gloves out and have a little nosey...

That's really interesting!!! My main reason for asking was for those days when I get two sessions in (make beads in the morning, let them cool, then turn it back on for an evening session) - I guess the roses might be a bit more susceptible to cracking than other beads, but it's good to know even I could crack the kiln open at a higher temp to speed things up!! Thanks for sharing, everyone!
