Blue Scale – Textile Fading Cards

Textile fading cards test for effects of light on paintings, documents and textiles with blue indicating scales.

Each textile fade card features pieces of wool cloth dyed with blue dyes of different degrees of fastness which are used as light fastness standards. The blue wool card allows you to monitor the net exposure to light given to objects on display and to alert conservators to adjust intensity of illumination.

These blue scale cards are manufactured in the UK exclusively for PEL to BS EN ISO 105-B08 which is the British and European standard for blue scale textile fading cards.
