After a another year of research, this posting has been revised due to research evolving.
I have come to the conclusion on the Welz and Ruckl debate, that honestly we will NEVER know who made what until proper documentation is available.
The majority of the research that has been done is by taking a documented shape and using the decor to match with other shapes that are not documented.
Unfortunately, I don't believe this research works because we are finding many Bohemian glass companies produced the same thing.
It is important to understand the majority of the research that is done on Ruckl and Welz is EMPIRICAL research which means it's an opinion given and not based on theory or fact.
I was very lucky to have a conversation with Deb Truitt in regards to the Ruckl/Welz debate. She explained, "The problem comes when extrapolating from a known to an unknown piece. We don't have enough documentation yet to differentiate among pieces from different companies. It was a business for the glass makers, and they made what the markets wanted so many pieces are similar. So, yes, call things Bohemian until we have documentation."
My intentions for this post is to help collectors understand if you are going to rely on empirical research, be prepared to change your mind often about attributions.
Please keep in mind, if you take a documented shape and find other shapes in the same matching decor, Welz , Ruckl and Harrach will bump into each other with this type of glass.
As another example: Take a documented Loetz Tango piece in red with a black rim, and match other shapes that are red with the black trim on the rim, collector's will find more than one glass maker was producing the same thing or let's say the collector is not aware Bohemian glass companies were copying off each other, and glass was matched by decor, the collector would think it was produced by one maker which is not true.
Sorry to say... but the Welz, and Ruckl attributions are not 100% correct. So I'm taking the advice I was given by calling it Bohemian and adding Export, because more than one company was producing the same type of glass and there is practically NO documented proof to know who made what when it comes to this type of glass.
HERE IS THE ORIGINAL POSTING:
Featuring 4 different decors in the same shape. This show and tell reflects from the "I Heart Ruckl" posting. A dance of colours in a contrasting palette with the impression of the four seasons.
For fun, I have given a flower depiction representing the "Four Seasons" by colour on each heart shaped vase.
Pic 1. Winter Holiday in Poinsettia. White lining with splashes green aventurine, oxblood red and a hint of yellow.
Pic 2. Spring Ahead in Bluebells, Cherry Blossom and Daffodils. White lining with splashes of blue, pink and yellow.
Pic 3. Summer Love in Wild Flowers. White lining with rainbow colours surrounding white buttons. Note: there is a tiny air bubble above each white button.
Pic 4. Fall Back with Chrysanthemums. Yellow lining in oxblood red and white.
There is a interesting article from the Journal of Czech Decorative Arts, Vol. 1, no. 1 Spring/Summer 2002. Featured articles and pictorials include “Tango Glass” by Jitka Lnenickova.
Here is a statement from the article:
"After 1903, glassmakers used for the first time a new colour component, cadmium sulfide (CDS), aka cadium oxide in a combination with selenium oxide, antimony oxide, copper oxide, manganese. These components coloured opal glass treated with cryolithe, feldspar and fluorspar.
Only by using such opal glass with it's high intensity of colour was it possible to produce the deep and rich opaque colors to produce the deep and rich opaque colors from a very thin layer of colored glass was sandwiched between two clear layers or sometimes produced with a colour inner layer and a clear overlay."
Every Heart shaped vase shown above does correspond with having thin coloured layers sandwiched between two clear layers. Certainly not a common commercial shape to associate with another glass maker. The top is three lobes and depending how you turn the vase, a puffy heart will take shape. Embossed scallop edge panels on the stem. The vase sits in a bed of what I consider applied flames. Rim is cut and no pontil on the base.
These heart shaped vases from Ruckl are 7" to 7-1/8" tall. Diameter of each rim is 1-3/4 inches and the applied base at the very bottom is 3-1/2.
