10th November 2006: Despite the fact that vase 20047 appears to be illustrated in Warmus "František Vizner: Sklo/Glass 1951-2001" image 1-10, the design for this vase is apparently the work of Vladislav Urban, and numbered 20048. Caption on image 8, on the "Sklo Union: Some Views" page,changed to reflect this.

23rd November 2006: NEW PAGE ADDED. It Is Not Sklo Union which has been added, in order to show pieces of glass, which are often assumed to have been made by Sklo Union. Nothing will be placed here, unless correctly and verifiably identified.

17th January 2007: NEW PAGES ADDED. French and German language versions of  the "Rudolf Schrötter: Designs for Josef Inwald", now added and working properly.
Thanks in advance for any suggested corrections for the German version.

15th March 2007: Information regarding newly identified designs by Rudolf Schrötter including "Ariel" added to the "Rudolf Schrötter: Designs for Josef Inwald" page.

1st August 2007: Image of  non-iridised "wood-grain" plate added to the "Sklo Union: Iridised Oddity" page.

29th August 2007: In the light of recent research developments, www.sklounion.com will gradually be expanded to cover the period 1945 to 2006. This is the date of the last hand-pressed production within the factories under study.
