Marquetry glass - Volume 3 - Foot and veining decors

Here is a study in decorating technique, with the hope that it would get easier to find glass distinctions or dividing lines. The goal is fairly clear, to find who is the attributable maker of this beautiful art glass. In looking at the various techniques and materials there are some good indicators that they were not all made by the same company

Foot decor

1.
this picture indicates what powders were used at the foot of the vessel. By far the most common decor is applied cobalt powders but they also used blue with green, red, orange and black Adventurine powders too (I will show the orange powder later in a post). Powders were also used throughout the glass in splotches; Blue, Yellow, Orange, Green and rarely black were used

2.
This example is more of an anomaly, it is red and purple molten glass pulled up into the flower. I would have thought this might be a different maker but the very same shape was made in the traditional satin glass

3.
Confetti was used in the foot decor as well (sometimes throughout).
There is a clear pattern of decor here: If the pink confetti was used the flower will be orange, when green confetti was used the flower will be Yellow... The vase shown is the only exception I have in my pictures.
Another anomaly has multi-color confetti decorating the foot, I will show that one in a later post

Veining decor

The use of what appears to be molten glass running vertically is actually a rod. The rod that is similar to a millifiori rod; The rod is always two colored with one color on the surface and one color internally.
This rod is applied when it is heated, it is worked into the surface of the hot vase; this application is similar to the bambus decor but usually much more organic looking

3.
The veining comes in three colors-the overall appearance can be many different colors due to temperatures, timing and technique. Sometimes the colors mix into one color while other times you see one color outlined by another (as seen in left hand corner)
1- Green veining: yellow cased with blue
2- Brown veining: orange with blue
3- yellow veining: Yellow with purple

Some patterns emerge here as well:
When you see green veining you might find a yellow or red flower as this is the most common decor.
If you find a piece with brown veining the flower is usually orange but can be red as seen in the amber types- the yellow flower is excluded; they are not seen together
Lastly, the yellow veining is quite rare and only appears in glossy type pieces... If yellow veining is used the flower is always red.
