2 'Merletto' glass vases with three lobed neck

Hi all.
I have had these two vases for ages and have no idea of their origin. I purchased them on seperate occasions from estate sales. They both feature the same three lobed neck opening, however one is pulled open petal style and the other left as is. They both have a very fine latticino effect and are cased (one in clear glass, the other in pale blue) with a flat polished base. They are not signed. They measure 14 & 16.5 cm tall.

The technique is called 'Merletto', and is created using asbestos netting. 'Latticino', by way of contrast, is made with applied glass threads.

It's not really my area, but I know that Harrachov Glassworks made this kind of glass under the series name 'Harrtil' - other factories made similar wares too, so it's not a guarantee.
