A cut Loetz 'Rainbow' vase.

Loetz introduced in 1890 its first 'Rainbow' glass comprised of a combination of pink-red, topas yellow, turquoise blue and brown splashes of clear glass. Soon it was followed by the popular combination of red, blue, green and yellow glass, either on crystal clear or on white opal glass. Loetz used this later type of 'Rainbow' glass still in the 'Series III' period. Most items were either smooth or structured by optically blown glass.
The mouth of my vase has a 8-fold cut neck and the body cutting is separated by two round cut grooves. The body itself is sharply 24-fold notch cut giving rise to sharp edges accordingly. The 'Rainbow' colors are applied oppositely as inner case complementary pairs of red-green and blue-yellow clear glass, allowing for many mixed in between colour tones - like orange or purple - as can be nicely seen from the fotos taken in bright sunlight, and being arranged as turning the red glass from the left, over the back to the right side. The production number of my vase is unknown, but from the cutting and the gilded '2.nd Rococo' style enameled ornament, it was possibly made in the early 1890's. The vase has a large polished pontil, stands 11.5 cm high and its diameter is 9.5 cm.
