I wonder if anyone could advise me...I bought a wonderful looking steel stove in Japan where I live...it never felt very controlable but...it looked superb... after the first season I noticed thre glass was always black and asked the maker fior advice... he asked for photos so I subsequently provided them.. he told me I should not have placed gasket all around the outside stove glass like an 'O' but like a 'U' thus leaving the top of the glass without gasket... I have no idea if this is correct and would like to ask my native speakers for advice... I would really appreciate your advice. iam not quite read to die ^^
