Hello everybody!
I need a little help identifying these glass cups.
made of what looks to be transparent blue/ purple glass with surface resembling stone.
Remind me a little of Mdina glass but much different to my opinion.
Thanks in advance!

;D Polish glass, made by Hortensja.
Silver salts are used to create the surface decor (which are also used in Mdina, that's the connection you spotted).
Not the most common of things to find. This range, which comes with a blue background and another in amber, were only made to order.
However they are a kind of tribute to an older style, and I can't for the life of me remember what, but there are discussions here about it. I'm sure it was Flying-Free did all the research on that.
Not having your glasses in my mitts, I might be tempted to wonder, but it is far more likely to be Hortensja than the older one.
Both are lovely. I've had an interest in this since I first found it, I'm a sucker for things using silver salts. 8)

Similarities to Knizek Pandora Sue?
-
;D Yes. I knew you'd know. :-* Your brain keeps info. Mine leaks.
The links you've provided seem to cover what we know, so far.
I did a search on Knizek Pandora and found lots of Hortensja Mimosa, wrongly attributed. ::)

Thank you for the information!
I have never heard of this maker.
The finish is very different, specific and beautiful. They must have had their own way of applying these salts.
Glad to see the examples in amber.
I have a set of 8 such glasses and each is different.
I am not sure about the purpose- any idea?

When silver salts (either silver chloride or silver nitrate) come into contact with the hot metal of the glass, they separate into silver metal ions and a gas. The silver metal reacts with the glass to create colours. These vary from a deep amber to a pale opaque yellow. They will turn red glass brown and blue glass much greener.
Sometimes, the silver metal molecules get into the clear casing and there, they can create an electric blue haze, or if they escape from the vessel, end up deposited on the outside as they do in much of Mdina.
Silver chloride is a weird substance, which goes straight from being a yellow crystal into a melting liquid as soon as it starts heating up. Silver nitrate is awkward stuff because it starts dissolving in the moisture from the air, but seems to produce the kind of patterns you have on your Mimosa glasses.
I would suggest you use them, if you want to, for any purpose you like. ;D
