ah. good idea. thanks. e 6000 works well for me

way cool! where did you get the lamp base? r.

I just read on craftweb that a digitry controller does not like to work if its thermocouple is too cold.

oh yea i can see that that sucks. just send it to mee and it will never bother you again. r.freight collect will be fine.....

You can use a kiln for both glass and ceramics with no problems. R.

your controller might get cranky. i put a space heater near mine untill the kiln heats up enough to keep it warm. hmmm. gonna get cold here as well. must check pump house.r.

I make my own wash. 8/2 alumina/ kaolin plus some cmc for green strength. Super easy to scrape off. I use 1/1 for molds.

Put a fresh coat or two of wash between firings. No need to prefire kiln wash.

you also need to kilnwash the shelf even if you use the paper. paper can fail if you have a hi temp misfire.

i would lower your first hold to 1100f or a little less. or put in another step with a hold there. your first hold is high enough for the glass to be soft enough grabbing thinfire smutch before it has a chance to get out of the kiln. maybe prop the lid a quarter inch at first. or just use kiln wash.

huh. if the mold has been bisque fired. (those have) then it has been fired to above 1472. i can see no reason why doing like they said would do anything to the ceramic 'interior structures' or whatever. i just see no science behind that statement. cynthia m, you got a clue i am missing? r.

What manufacturer recommends That? It makes no sense to me. R.

need more info. are you firing green ceramics? if not i see no need to prefire. just kilnwash and use. r.

Wow

well there is organic stuff in whatever binder they use and whatever the chinese haik brush contributed, i do know that my epk/alumina hydrate /cmc mix will go rotten eggy. i used to use a low grade of gum arabic as a binder in kw. whew! toe cheese bugs in that binder. r.

it is supposed to turn green and slimy.
Just what did you expect to happen?

Damnable Kevin. Now I have to clean coffee of my keyboard. Ha.

i would fire it to 1000f or just put it in with whatever firing you do next. if that does not help then what you have is a result of how the mold was poured. the clay can be compressed in an area and less able to easily hold kw.

bead mandril pushed out from behind after every hole.pita. next time i have a bunch of holes to drill i am going to line up a helper. i will use 3 or 4 drill bits and the helper will be poking out the plugs while i drill. r.

every time i use a cracked piece the crack shows.
