Nationalmuseum of Sweden Inaugurates with ArtRatio SmartGlass Table

Introduction

The Nationalmuseum of Sweden was inaugurated on 13th Oct 2018 after a 5-year $130 million renovation with the main objective being to ‘Let in the Light’.

The inauguration ceremony was presided over by the Swedish Royal family, including HM King Carl of Sweden, HM Queen Silvia, HRH Crown Princess Victoria and HRH Prince Daniel.

Also present were the Minister for Culture and Democracy Alice Bah Kunkhe and Museum Director Susanna Pettersson.

The Nationalmuseum is the principal museum of art and design in Sweden and has a collection of 700,000 objects, including sculptures, paintings and drawings from the late Middle Ages to the beginning of the 20th Century.

Since there is now more natural light entering the building facade, the museum requested an ArtRatio customised table featuring Variguard SPD Smart Glass to protect the most sensitive items from light damage.

The works being protected by the ArtRatio display case are the oldest in the museums collection and include the following:

  • Book of Hours, St. Christopher carrying the Christ Child, watercolour and gold on parchment, Spain, c1400.
  • Book of Hours, Arrest of Christ, watercolour and gold on parchment, France, c1500.
  • Ivory object, Christ on the Cross, France, c1350.
  • Book of Hours, St. Catherine and Kneeling Donor, watercolour and gold on parchment, Netherlands, c1430.
  • Book, The Hours of Giraldi-Guicciardini: The Rising of Lazarus; Death Carrying a Scythe; 1500-1525, Watercolour, gold on parchment, Italy.

Technical Specification

This project was run in collaboration with Variguard (division of Research Frontiers). The glass was manufactured by Smartglass International.

The smartglass table-vitrine allows the display of light-sensitive works of art whilst limiting damage from light exposure.

This allows greater use of natural daylight within the building facade, facilitating sustainable art collections.

The top and front smartglass facades are opaque in the OFF state, blocking 99% of UV, 50% of infrared and 99% of visible light.

When someone approaches the table, the infrared proximity sensor triggers silently, simultaneously activating the smartglass and internal LEDs.

An ‘anti-flicker’ delay, configurable from the In-Table Intranet, avoids rapid on/off cycling when the museum has large visitor groups.

The table logs popularity by counting the total time that the object has been viewed, which can help to measure visitor engagement. This data is visible on the In-Table Intranet home page.

Materials

The materials used in this table include

1. Interior lining of 6mm thick KRION which is antibacterial, fireproof, anti-static, highly durable and 100% recyclable. Colour: Mocha 6504. For full technical data, please see: http://www.krion.com/en/technical-data

2. Exterior is MDF, hand and roller-painted with water-soluble lacquer

3. Variguard SPD smartglass, laminated by Smartglass International, is 11.5mm thick, anti-bandit spec to BS EN 356 (P4A security). Transmittance in the ON state is 49% and in the OFF state it is <1%. Surface reflectance is 3% on the front and top surfaces. Blocks 99% UV at all times.
