Hi,
these look like Czech, around 1920s-30s era. Typical colour scheme for this period,& yes, the use of cased glass was a feature of these items.
Have a look at the base for signs of wear appropriate to items of this age. Some are occasionally marked on the base "Czechoslovakia".
The tall vase has rustic-style thorns which are a throwback to Victorian glass, but the colour scheme is pure 1920s-30s.
The bulbous vase would have had a metal flower arranger on top.
Similar items are pictured in the book "Made in Czechoslovakia" by Ruth Forsythe. Also see Truitt's "Bohemian Glass II".
Hope this helps!
