Kralik or Loetz Threaded Glass Footed Bowl...

I've always assumed this piece was most likely Kralik, but I have now evidence. It measures 6" in diameter and 4" tall. The feet have been shaved down to make it set even. Any thought are greatly appreciated.

 

I have no idea who made this though I've looked at a lot of what I call rose bowls but I don't know if that's an official name to no avail. This is more a question. I think of threaded as being applied strings of glass but yours looks to me a bit more like it's cut or impressed. I have no idea if I have my terms right or if that's what you've got, just a question. It's very pretty.

 

I guess the correct term would be "crackle". Like these - http://www.ebay.com/sch/Kralik-/160..._from=R40|R40&_nkw=glass+vase+crackle&_sop=16

 

I have no idea, it almost looks like your pattern goes in like it's impressed into the surface while those crackle ones look molded and go out from the surface but it's hard to tell from a photo and I'm not good with glass anyway. Sorry I have questions but no answers. Hopefully someone else will know.
