Once a wooden sculpture has been dehydrated cracks will appear, where even exposure to high relative humidity will not make the cracks close up entirely. However, conservators can fill the cracks with a variety of materials to create a unified visual impression. What should I ask for when matting and framing works of art on paper? Mat board should be made from 100% rag or lignin-free cellulose. Sometimes those labelled as "museum board" or "conservation board" are not of the highest quality. Alkaline buffered boards are not sufficient if the board contains wood pulp. Photographs should not be matted with alkaline buffered boards as some prints are adversely effected by alkalinity. Hinges are used to attach the work of art to the backboard of the mat. They should be made of Japanese paper, and should be adhered with wheat starch paste. Pressure sensitive adhesive tapes and pre-gummed tapes should not be used. Photographs are often attached to the mat with photo corners.

Who am I? I am an Estonian too, my name is Jüri Ülesoo. On the photo you see me with my dog Josper. I''m not really the artist but I like art. Some years ago I made some oil paintings but not now. I''ll try to be the curator for some Estonian artists on the Internet and here you see my first step - Navitrolla''s Gallery (thanks to Lile Elam and Art on the Net). The problem is that few Estonian artists have computers, good communication connection and time to learn and use it. I want to show their works to the whole world and the Internet is the best tool for it. Until the artist has his (her) own Internet connection and e:mail address I will be mediator for him. So, you can e:mail your opinions to me and I will give them to the artists. During the "day" I work as a Marketing Manager in the Estonian, Latvian and Lithuanian area for Finnish concern VALMET (for Valmet Automation - producer of process automation systems). I am a member of Lions Clubs International.

On view throughout the Museum are an especially varied range of objects, images, and room-sized installations, including masterworks by some of the most influential artists of the past forty years, along with an impressive number of recently acquired works by emerging artists. Open Ends includes eleven distinct exhibitions and ten large-scale works and installations that examine key themes and lines of affinity that define contemporary art and artists. The exhibition opens in three stages. Architecture Hot and Cold presents a wide range of images of architecture principally drawn from the Museum’s collections of photographs and architectural drawings. The exhibition includes works by architects including Archigram and Rem Koolhaas are shown alongside the photography of Andreas Gursky and Robert Adams, for example, as well as works in different media by artists such as Gordon Matta-Clark, Andy Warhol, and Joel Shapiro.
