I recently acquired a pair of Welz Oxblood Trophy vases in a rarely seen shape that was included in the Tango Exhibit. The example of this shape shown in the exhibition was in Variegated Pink and White. This is only the second or 3rd example of this form I have seen, and to find it in the distinctive Oxblood decor with the fairly distinctive interior color was a bonus. These examples are the end pieces in the first image.
In all examples of this decor, and other also shown in these images, the interior is lined with clear. This varies from the labeled Oxblood Ruckl example as it does not have a clear lining, while there is another example without a label posted on CW which is said to have a clear lining.
I think all this proves overall (the lining that is) is that this type of production detail would certainly not be a marker for any one company. This is stronly supported by the fact that the same shape and decor from the same company is found both with and without an inner lining of clear.
The images below are as described:
1) Welz Oxblood decor examples, with the center back piece having a different interior color. In the case of the different interior color, it gives the example a slightly different look overall. The shape is a well known Welz trophy shape.
2) Welz Oxblood grouping , all examples having the same casing layers and interior colors.
3) Welz Oxblood examples on unique Welz shapes.
4) Welz trophy vases, and as with most houses, same shapes were produced in different sizes. In this case, the large trophy vases are not seen all that frequently. Certainly less common than the smaller form.
