kdryvz Posted May 1, 2021 Report Share Posted May 1, 2021 Hello everyone.I am new to this forum and it is nice to see such a lovely place to share things. I want to be a part of it. I am working as a technical support engineer in Istanbul. The products we cover are kilns, wheels and other equipments. As my main interest is electrical problems, one of our customers has asked for help about this soot issue. She accidentally fired her kiln when she had forgot a cup which is filled with a little olive oil at the bottom of it. When she came back, the kiln was full of soot. The walls, the flue and everywhere was black. She asks what she can do to remove this layer from the walls without damaging the kiln insulation. Is there anybody experienced that situation before? Is there a certain method to get rid of this problem? Any help will be appreciated. Thanks! Link to comment Share on other sites More sharing options...
neilestrick Posted May 1, 2021 Report Share Posted May 1, 2021 The soot should all burn out if she fires it up hot enough. How hot did she go? I would expect normal firing temps to burn it out. Why was there a cup of olive oil in her kiln? Link to comment Share on other sites More sharing options...
kdryvz Posted May 1, 2021 Author Report Share Posted May 1, 2021 I will advise a hotter firing to her. I hope That will burn the soot out. She has many students so she is suspicious about one of them left it there. Thanks for your reply. Link to comment Share on other sites More sharing options...

Agree, but only if the kiln has enough fresh air flow throughout the kiln to convert the soot to gas; said another way, lots of ventilation on next firing in both the kiln and the kiln room!

kdryvz Posted May 2, 2021 Author Report Share Posted May 2, 2021 Worth to try. She mentioned about some chemical solution to put in the kiln. She was even planning to sand the bricks inside. Of course I didn’t let her ruin the kiln. I will consider increased air flow. Thanks for these great answers. Will write back the results. Link to comment Share on other sites More sharing options...
Babs Posted May 2, 2021 Report Share Posted May 2, 2021 Can't see why it won't just burn off. All bung holes left open, well ventilated room. Would only be carbon really. Is it an electric kiln? Just thgat you mention flue Link to comment Share on other sites More sharing options...
kdryvz Posted May 2, 2021 Author Report Share Posted May 2, 2021 Yes it is an electric kiln. Saying the flue, I meant the upper wall of the kiln. Especially around the up ventilation hole, there wass a mass of soot hanging. I hope to solve this problem with the burning. Thank you. Link to comment Share on other sites More sharing options...
Babs Posted May 2, 2021 Report Share Posted May 2, 2021 Vacuum kiln thoroughly , element grooves last. Then fire, I would be tempted to do a bique fire, pots and all after the vacuum, shame towaste the energy. Link to comment Share on other sites More sharing options...
