With everyone from the Bohemian glass collecting world arguing over who made what. I thought I would share some of my favorite cased glass pieces. To me "Czechoslovakia" is a place of origin that needs no more research- it means it was produced for export, between the wars and is cheap and decorative. Glass for the masses at a price they could afford.
Cased glass means: A glass vessel with an opaque base and applied glass decor with a crystal layer of glass to increase the color and dimension of the decor.
1. Millifiore cane pattern
2. Powder (glass dust).
Multilayer of powder and glass chips
3. Powder, then crackle pattern.
Glass chips and glass dollops.
Millifiore cane
4. Various glass dollops, glass chips, threads and canes

Beautifull!!
Wow ! quite a few that I have never seen before.
thanx mate!
Jericho, do you happen to made the 2nd and 4th pieces in the last picture? I am curious as I have bowl with the exact same colors and pattern.
last pic piece two has an orange base with color windings raked up with a tool, another method would involve pressing in a mold (to create ridges) then smoothing out while pulling the piece. forming a square then acid bath. I'm not sure if the acid was placed hot or cold after the piece was cooled. I suspect all satin, glue chip, flashed pieces were treated cold.
last piece is a confetti piece with orange base. glass chips with bullseye canes (like black agate) were added then cased. the caned were probably imported from france or italy in the form of rods then broken to make chips.
Thanks for the info, Jericho. I do not know much about the making of glass. I did see a short video of a kralik piece they were showing that had mentioned the raking method though so I think I understand that.
But I do have a couple more questions if thats ok.
What are the difference in the acid bath cold/hot?
If my piece look the same from the inside and outside...does it have a clear ground or no ground? Is the ground the color everything is "cased" in?
Does the 4th vase also have an orange ground as well?
Sorry for all the questions.
Hi Jerico i think it would have been easy enough for them to make their own rods it one of the basic techniques that the glass maker uses. Ususlly the Gaffer will get his assistants to make them . it is a bit like making toffee .
good point, some of these factories were massive.
KS85. i like questions and even different opinions- each of us has insight that we need to share. lets see...correct me if i did'nt get the point.
1. here is the difference in the cold method and hot methods of applying oxides, acids and other chemicals. in the hot method you get a crackle effect and sometimes you see the color seep into the cracks of the expanding piece. in a cold method the surface of the glass is eaten away or tarnished in some way without crackling. glue chip is a cold process because even the postil is effected by the solution (clearly pontil first then glue chip later).
2. base color... if the base color is opache it most likely has at least 4 layers example: Crystal glass,color base glass, decor color, crystal.
3. clear base has three layers- Crystal, floating decor, crystal
4. the fourth vase is the blue crackle it has crystal, white, blue, crystal layers, then it is sprayed hot with an acid to create the flash finish...if you mean the 4th vase in the fourth pic. it has no base color so it is the same on the inside as the outside. hope this helps
I think I understand. Thank you very much for the detailed replies Jericho.
