A unique Loetz 'Stripes and Flecks' Décor.

In the year 1900, Prof. Koloman Moser designed for Bakalowits his famous decor 'Streifen und Flecken' consisting out of silvery dots and vertical stripes on a dark blue glass with PN=85/3790 (1900). Three years later, his black version on opal white glass came 20 years too early and caused many controversions. Loetz used Prof. Moser's decor in many variations. It comes silvery on blue, green, orange and purple glass as well coloured on crystal clear, 'Blitz' and opal white glass and was often used for lamp shades, too. A variant with orange opal dots on green glass is the Loetz Ausf-122 (1911). Other derived variants are Phaenomen Gre's 1/215, 1/696, 2/314, 2/474, 3/430, 85/3833 and Argus (2/351). In 1929, Otto Prutscher designed a variant showing horizontal stripes, see eg my CW post stories/321422.
The shape of my vase is almost exactly matched by PN=II-2/473 (1902), or showing the same foot, but four lipps by PN=II/2119 (1905). All PN's have a mouth with inverdly folded lips and my vase shows the set-off foot made by a circular constriction near the bottom. Other décors on vases of similar shapes are 'Colchicum, Carrageen', the Phaenomen Gre's 2/466 and 3/430.

Usually the vertical stripes of the décor are formed by straight linear lines. In the present vase, you may observe small pairwise identations disturbing the linear line pattern. To my opinion, the glass master grabbed with a pair of tweezers the hot, already decorated, glass mass parallel to the stripes and twisted then the glass surface by about 90 degrees and caused thereby the observed S-shaped deviations. There are 12 pairs of tweezer traces, six in the upper and six in the lower third of the iridized, white opal inner cased vase covered by orange 'Streifen und Flecken'. As I never met this type of décor before, I allowed for the description 'unique' in the head line.
My vase stands H=18.8 cm, Dm=9.5 cm Du=6.5 cm. It has a polished pontil and weights 410 gr.
