fravsss Posted April 26, 2020 Report Share Posted April 26, 2020 Hey guys. I'm a begginer in ceramics, so I made a sawdust kiln and put some pieces to bisque fire, but I couldn't get to the right temperature because I was stupid and covered the kiln at the wrong time, I should have waited more, but my question is: can I put it to bisque fire again? They didn't get any closer to the point they should, they are all black and doesn't make the sound of bisquefired pots. Is it ok to try firing it again? Please help me.

neilestrick Posted April 26, 2020 Report Share Posted April 26, 2020 Can you tell us more about your kiln? By sawdust kiln do you mean a pit, or something with more engineering than that? If it's a pit, the pots won't get as hot as in a regular kiln. Link to comment Share on other sites More sharing options...
fravsss Posted April 26, 2020 Author Report Share Posted April 26, 2020 It's a pit, actually it's in my barbecue grill lol, I'm trying to make it work as a pit. And I don't think it got hot enough. Link to comment Share on other sites More sharing options...

JohnnyK Posted April 26, 2020 Report Share Posted April 26, 2020 Since it is your grill, why don't you try firing with a bunch of charcoal briquets, or some very hot burning wood to get the temp up? Do you have a thermometer to tell how hot it gets? Link to comment Share on other sites More sharing options...

liambesaw Posted April 26, 2020 Report Share Posted April 26, 2020 Will be tough to get it hot enough for your pots to ring in a BBQ. You've got no insulation so the heat can't build up very well. Link to comment Share on other sites More sharing options...

liambesaw Posted April 26, 2020 Report Share Posted April 26, 2020 Oh wow that's really nice, I wouldn't even try it in something like that! If it does get hot enough you might destroy the bbq! But yeah I think it'll still be hard in that one Link to comment Share on other sites More sharing options...

Gotta try something else then, any suggestions? Considering that I'm in the country (I live in a small town in Brazil) and here doesn't have a place that sells "pottery stuff" to make a proper kiln, so...?

If you have some extra brick you could try stacking a little kiln on/in the ground! The bricks arent designed to take that much heat, so you may only get to fire a few times, but better there than in your outdoor kitchen Link to comment Share on other sites More sharing options...

Babs Posted April 26, 2020 Report Share Posted April 26, 2020 Line a metal garbage can or 44gal drum with top cut off with ceramic fibre..cut draught holes at bottom fill with sawdust and pots and light it up lid placed on after the fuel has caught Or Cut a few slots in drum at various heights fill with pots and sawdust, light up and put lid on. This is low fired stuff Link to comment Share on other sites More sharing options...

Magnolia Mud Research Posted April 26, 2020 Report Share Posted April 26, 2020 You don't need fiber insulation for sawdust firing or "pit firing". Think of this firing technique as a trash burning in a metal can. LT Link to comment Share on other sites More sharing options...

Magnolia Mud Research Posted April 26, 2020 Report Share Posted April 26, 2020 You can also think of this as a bricked up trash burner. I fired with scrap wood and tree limbs using a found section of a concrete culvert pipe and leftover house bricks. Lasted several months of trash and other firing. Make bricks from local clay for you "metal can" LT Link to comment Share on other sites More sharing options...

Think of this firing technique as a trash burning in a metal can. LT My husband built a barrel-fired kiln using sawdust, and today we did the second firing with it just to test temperature. We started at 4:30, and it is about 1/3 finished. It has reached 640 F. I will be hot for about 20 hours. I don't know how much hotter it will get. I'll check it throughout the night. It is built by a plan (Alternative Kilns & Firing Techniques: Raku * Saggar * Pit * Barrel) exactly by the directions. Link to comment Share on other sites More sharing options...

There's so many options now that I'm kind of lost, I think I'm gonna try everything lol. Thank you for the help btw. Link to comment Share on other sites More sharing options...

I am learning and experimenting. I want to do variations with firing. My husband has another Idea to build something that will fire to at least cone 6. I am glad he will do this for me. I love the barrel-fired look, but it is not food safe. Good luck and the book we used to pattern--is so helpful. Link to comment Share on other sites More sharing options...

I love the barrel-fired look, but it is not food safe. Good luck and the book we used to pattern--is so helpful. At about midnight, I checked the temp. of the barrel-firing. It had exceeded 980 F and the flue was smoking strongly. This morning it was barely smoldering and I could see the pottery. I was disappointed about the heat and time compared to the first firing. I haven't been able to check the pottery but it didn't fire but for about 15 hours. Anyway, I am anxious to clean up the pottery and see what I have. Only two items were broken out of twelve. I am still learning and experimenting... Link to comment Share on other sites More sharing options...
