On page 175 of Das Bohmische Glas1700-1950 Band iv in the section for Glasfabrik Elisabeth there is a plate with three vases on. The right hand one appears to be in this deep pink red iridescent finish and appears to have the same applied dark purple iridescence on it in the form of rigaree ending in prunts with the same or very similar little tooling mark. In addition, the rose bowl next to it has prunts on it in the same purple iridescence which look very like my prunts but they don't have the tool twist in the middle.
I think these vases are Glasfabrik Elisabeth, Kosten bei Teplitz. The one is the book is dated 1900-1910.
