Hello,
Has someone expirience with "self-reduction" glazes? Is it possible to
achieve local reduction effects in glazes and engobes for simulating a wood
fire in electric kilns under oxidation atmosphere?
My aim is to rebuild 11th century german ceramic. The old german used an
engobe, made of red clay with flux (I think beechwood-ash) or a simplyfied
terra sigillata (red clay with deflocculant leaved undisturbed for one day).
Both works well at Segers cone 6a (1200 deg Cel) building a semimatt
surface.
At the moment I experiment with adding amounts of Carbon or SiC to an
engobe.
Perhaps someone can give me usefull hints.
Thanks
Michael
