Holding Temp

Recommended Posts

I am making a mural with tiles I bought from a store that has a matt finish glaze on it. I painted them with 05 glaze.  I've done this before in my old Duncan kiln with no problems. I recently bought a new l&l kiln that is digital.  When I go to fire them, should I do a slow glaze with holding?  Or just a slow glaze firing.

Any reason for going slow at all?

 

I have a L&L in my classroom, and use the Fast Glaze setting, because of the quick turn around it gives me. I haven't had an issues, with doing so.

Great, thank you.  I haven't had any problems .... yet. I fired a test tile with different glazes on it.  It fired good.  This mural had multiple layers of glazes on it, that is why I was worried.

Lid closed. Peepholes closed if you have a downdraft vent. Top peephole only open if you don't have a downdraft vent.

 

I always wondered about that.  My old Duncan, no downdraft, I only left the peepholes out during a bisque firing. But it had a hole on the lid.   My new L&L, no downdraft, I do the same. What is the purpose of leaving the hole open on a glaze firing?

Yes. Leave it open the entire time. I also used to fire this way. If you don't there is a chance you can have glaze defects from the burn offs. Also if your firing indoors with that kiln, make sure you have a window open or something. Also don't be in the room with the kiln, fumes are coming out of that top peephole like crazy.

Oh, I am learning so much.  Should of found this site sooner.  I have had glaze problems in the past. Makes sense now.  The kiln is in the garage.  Nobody is out there when it's firing.  Thanks for all the great info.

I found that my glaze defects weren't solved 100% by the top peep hole open. I ended up going with a down draft vent and it made my glazes a lot better. Also I think people on here would recommend if your firing in your garage to open the door a foot or so when your firing your kiln so there is new air coming in and the radiant heat has a place to disperse.
