Since decors were reproduced by several Czech glasshouses, shape becomes all important. Fortunately for
the collector of Rindskopf glass, there are some basic guidelines:
1. Distinctive three-side or four sided tops in many decors and sizes.
2. The use of feathering--though Kralik and Loetz also used it.
2. Definite shapes and glass colors
But the best way to learn is side-by side comparison. Any two pieces with the same decor or shape belong to the same company.
AND REMEMBER: EVEN MUSEUMS MAKE MISTAKES. THESE RINDSKOPF VASES ARE HOUSED IN KRALIK CASE 254 AT THE PASSAU MUSEUM:
Same shape: different decors. This is only a sample. Even the Passau Museum makes mistakes: they have classified some of these shapes as Kralik. Thje last two photographs illustrate another Rindskopf characteristics: they would produce the dame decor in fire polished/ponti and cut/no pontil,.
Next,. we come to size. You will find Rindskopf vases, same shape, same decor, in different sizes. The largest: 13.5; the smallest: 6" Here are some examples, in the fifth picture, the contrast is between a 9" and a 6"--I also have it in the 13.5" (see above)
Next we come to decor. I have already covered them in my article on Rindskopf for http://www.loetz.com, so a few examples will suffice:
