Pair Czech 1930's/40's Orange & Blue Glass Tango Vases/Vase

Description

A superb pair of 1930's Czech/Bohemian bright orange blown glass vase with applied dark blue glass rim and handles.  Probably by Welz or Kralik.  Known as "mono-coloured" or "tango" glass, this technique was developed by Loetz around 1914.

Size

Measure approx 5.5 inches tall by 4.5 inches in diameter at widest point.

Condition

Both have faint manufacturing flaws/lines to the inside curved section, all shown in final pictures. They look a little like cracks, but are only on the inside orange layer, and occur in the exact same place on both vases, so clearly part of the manufacturing process and not damage.
