Marquetry glass - volume 2 - Shapes and textures

In looking for the dividing line that would divide one maker from another I categorized all the Maquetry glass by texture and shape.

In looking at texture first you can plainly see that there are five main types of marquetry pieces I have listed listed in the past.
1- Satin glass: the most numerous
2- Amber glass: darker version of satin glass
3- glossy glass: the base color opaque glass with natural surface texture
3- Iris glass: iris-style reflective finish
5- transparent glass. Crystal clear or smoke glass

Satin glass is the most common type of marquetry about 65% of the images are satin texture
They come in two basic styles of pontil type (ground rim or Pontil)- this would not be a good dividing line because there are only large pontil types while you can find the cut ones small, medium and large

The amber glass stands out because it’s the only glass texture that is perfectly consistent. The amber all contain the as same base color, same flower color, same surface texture, same confetti applied the foot.
The amber series looked like they were produced by a different company but then you realize they share some of the shapes with other surface textures

The iris are a pretty rare group with a strange dividing line. If the flowers are yellow the 3 flowers are placed in a tradition way (equally spaced). If the flowers are red they are only spaced in a single cluster to one side

The glossy look the same as the satin with a few exceptions:
A. Single flower (unique), multicolor confetti (unique)
B. A lamp-vase with orange/crackle base layer, red and purple molten glass pulls (unique)

In the transparent marquetry there are actually three variations:
1. A crystal clear base with confetti or powders covering the entire surface (similar to glue chip)
2. Tradition decor with crystal clear base and glossy finish
3. A crystal clear base with confetti or powders

In regards to the shapes there are 33 different ones I have spotted (might be a few unaccounted for out there). Most of the shapes you see come in only one size (only 2 exceptions). This is interesting for me because in many glass companies you have one shape that comes in 3-6 sizes-
speaking of size the largest Marquetry is 16” and the shortest one is 7 1/4”

The other thing that is interesting is that while Kralik (Interchangeable name) could make The same form with two pontil types in the Marquetry series they pieces stay consistent- if a shape comes in pontil it stays in pontil, if it is found with ground rim it will only be found in ground rim.
This could be a good start to a dividing line because certain shapes and rim types would fall on either side of the line- you can almost say all pontil pieces were made by.....

I still can’t say for certain who made what but stay tuned
