Emma Law Posted April 5, 2021 Report Share Posted April 5, 2021 Hi folks! I'm new to firing my own kiln pottery but am keen to have a go at raku and wood firing - I'm using different clay bodies and especially interested in using paper clay. I've recently bought some round kiln shelves for a gas raku kiln, I also bought some batt wash I read that it is advisable to fire new kiln shelves before painting with batt wash but I cannot find at what temperature My tutor at college said she doesn't know as she never uses batt wash in her home kiln! - However, I am going to be experimenting with using various additions to local salty clay so, I think it wise to protect the shelves Does anyone have advice regarding this/ Perhaps I just need to fire them for a short while to ensure they are thoroughly dry Link to comment Share on other sites More sharing options...
neilestrick Posted April 5, 2021 Report Share Posted April 5, 2021 With cordierite or high alumina type shelves there's no need to pre-fire them. Someone else will have to chime in on silicon carbide shelves, because I haven't purchased any in a really long time. That said, the last batch of silicon carbide shelves I bought 20 years ago did need to be fired once, or they would leave black stuff on the bottom of the pots.

Welcome from sunny Langdon Hills, about 60 miles north of you. Depending on flatness/size of work, you can also fire on cookies/waster slabs to protect your shelves.
