Sunny Posted January 9, 2015 Report Share Posted January 9, 2015 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. Link to comment Share on other sites More sharing options...
Benzine Posted January 9, 2015 Report Share Posted January 9, 2015 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.

neilestrick Posted January 9, 2015 Report Share Posted January 9, 2015 Because tiles lay flat on the shelf they heat up more unevenly than most forms, so the 'Slow Glaze' setting is appropriate. There shouldn't be any need for a hold time at the end of the firing unless you're having glaze problems. Link to comment Share on other sites More sharing options...
Sunny Posted January 9, 2015 Author Report Share Posted January 9, 2015 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. Link to comment Share on other sites More sharing options...
Sunny Posted January 9, 2015 Author Report Share Posted January 9, 2015 These tiles are 12". I can only fire 5 at a time. Do I prop the lid, leave peepholes in or out? Link to comment Share on other sites More sharing options...
neilestrick Posted January 10, 2015 Report Share Posted January 10, 2015 Lid closed. Peepholes closed if you have a downdraft vent. Top peephole only open if you don't have a downdraft vent. Link to comment Share on other sites More sharing options...
Sunny Posted January 13, 2015 Author Report Share Posted January 13, 2015 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? Link to comment Share on other sites More sharing options...
neilestrick Posted January 13, 2015 Report Share Posted January 13, 2015 Stuff burns out of the glaze during firing, so you want to leave the top peep open to vent it. Link to comment Share on other sites More sharing options...
Sunny Posted January 13, 2015 Author Report Share Posted January 13, 2015 Thank you. Do I leave it open during the whole firing? Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted January 13, 2015 Report Share Posted January 13, 2015 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. Link to comment Share on other sites More sharing options...
Sunny Posted January 13, 2015 Author Report Share Posted January 13, 2015 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. Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted January 14, 2015 Report Share Posted January 14, 2015 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.

Red Rocks Posted January 16, 2015 Report Share Posted January 16, 2015 Ok to leave the peep open the entire time it is cooling? Link to comment Share on other sites More sharing options...
neilestrick Posted January 16, 2015 Report Share Posted January 16, 2015 Yes, you can leave it open during cooling. Link to comment Share on other sites More sharing options...
Sunny Posted January 16, 2015 Author Report Share Posted January 16, 2015 Even if it's bitterly cold? My kiln is in the garage. It can get pretty cold in there. Or does that small hole not make a difference. Link to comment Share on other sites More sharing options...
