Photo number 1 here shows the two pieces I've been writing about, and Photo number 2 shows the ground pontils of both pieces, side by side. Photo number 3 shows the decors listed in the Musterschnitte for Max Emmanuel design 346/366, while Photo number 4 shows the decors listed for Form Nr. 622. Both mention "Ozon Cisele", which would be ozon oil spots, right? Maybe, but the oil spots on this piece are definitely darker than the ground color ozon, which seems to be a very light blue.

Looking at the details, the Form 622 seems to be on a green ground (Diana?), but if you look at the ground pontil, you can see what appears to be three colors - the dark blue oil spots, the (Diana?) green, and also the light blue ozon color. Since cobalt cisele is not listed as a decor on this form, could this be more accurately called "Ozon Cisele?" Or, is it just that cobalt cisele is an unlisted decor on this form? Certainly other examples exists where not all known decors are listed in the Musterschnitte.

Based on the evidence in the Loetz books, the two handled piece is certainly "Ozon mit Diana Cisele". The shorter piece, I maintain, MAY be Ozon Cisele (on a Diana Glatt ground). Or, it could just be cobalt cisele.

It does seem to me, however, that Diana and Ozon are most often seen together, although their relationship is not a monogamous one. :)

    You are correct that when a color precedes a decor name like "Cisele" the color refers to the colors of the spots when the word "mit" (with)and the ground color have also been previously given. I think this nomenclature also has to do with the evolution of the decor known as Cisele. In the Musterschnitte Loetz (usually but not always!) lists the color of the ground first and then the decor; i.e. Cobalt Papillon, Crete Pampas, etc. Diana Glatt - would be a plain looking piece of green glass with a thin coating of satin iridescence(Glatt). The decor, Cisele, was first described as "an opaque application of variously sized silver-yellow granules" but later a "decoration with small spots of colored glass". Diana Cisele would be a piece of green glass with an oil spot decor on it(Cisele). I have 4 examples of "Diana Cisele" where the spots and the glass are Diana! When you look at the description in Band2 for your PN622 vase note that the decors"Pampas" & "Rusticana" are listed without ground colors noted. Because both of these decors come in other ground colors, I think that there was an assumption here that these were all Crete productions.

    Warren, I miss spoke on the Diana/Diana. My pieces are all documented - shapes and decors - but the "Diana Cisele" describes the decor not the ground which is clear! What is even more curious is that my pieces as well as yours were all produced by Max Emanuel! Maybe he had thing for a "Diana". Anyway, here's a link to my web album discussion on Cisele and the "Diana Cisele" pieces:
