In the second week of July in 2015 the International Hot Glass Symposium will be held in Haapsalu already for the tenth time. It is a unique traditional professional glass blowing event in Estonia, which has been consistently organised in Evald Okas Museum with the initiative of a glass artist Kai Koppel.
Titles of the symposium have always been chosen, in order to highlight the seaside location of the Glass Days as well as memorable improvisational atmosphere of the symposium.
This time the theme and keyword is "10!". The organisers offer to all participants, guests and other interested parties the freedom to interpret it either as the festivity of an anniversary, joy of birthday, arrival of puberty, calculation result, maximum value of an assessment scale or otherwise.
The organisers plan to enliven the symposium with glass exhibitions taking simultaneously place elsewhere in Haapsalu, to expose the best works from previous years and to introduce a different type of glass art compared to the blowing and casting techniques characteristic to the symposium.

The Haapsalu Symposium is remarkable compared to other similar events held elsewhere in the world, because the glass kiln can be used round-the-clock, and freedom of creation, readiness for experiments and realisation of new ideas arisen in the course of work is always considered more important than time. Thereby the participants always help each other. Thus the characteristic features of Haapsalu Glass Days are unique common creative energy, spontaneity, playfulness and exclusivity.
Glass art and especially glass blowing is enchanting for spectators as well. Glowing glass and its moulding is always intriguing and appealing, and the museum yard is open to everybody.

Traditionally the works completed in the workshop will be exposed in the museum after the Glass Days.
The exposition following the workshop is started to prepare already during the workshop, providing the audience an opportunity to monitor also the process of completion of the exhibition. At the same time, this provides freedom to the artists to change the original idea, if necessary.

The exhibition held in Evald Okas Museum is special in Estonian glass art for the fact that blown glass is rarely exposed in Estonian exhibitions.
