Tweaked the saturation of wool, making wool blocks slightly darker than before. Retrieved from " https: The dyes have been chosen so that each reference takes about two to three times longer to begin fading as the next lower reference in the scale. A rating between 0 and 8 is awarded by identifying which one of the eight strips on the bluewool standard card has faded to the same extent as the sample under test. The Blue Wool Scale measures and calibrates the permanence of colouring dyes.
They consist of eight strips of wool mounted side by side on a small card; each strip or reference is colored with a blue dye that fades after exposure to a known amount of light.
The dyes have been chosen so that each reference takes about two to three times longer to begin fading as the next lower reference in the scale. Under normal solar testing conditions, reference 1, the least permanent, will begin to fade in 3 hours to 3 days, depending on geographic location, season, cloud cover and humidity; reference 3 will fade in 5 days to 2 weeks; reference 6 in 6 to 16 weeks; and reference 8, the most permanent, in 6 to 15 months.
These scales are used for paint lightfastness testing under international standard ISO B , and are also used by gallery curators to measure the accumulated amount of light received by museum displays of paintings, textiles or photographic prints.
The blue wool scale cards willl normally be used in conjunction with grey scale cards in order to assess the degree of change. This table below gives one version of the eight blue wool lightfastness levels, from 1 fugitive to 8 extremely lightfast , with the amount of light exposure required to produce a color change at each level and the approximate match between the eight blue wool and five ASTM lightfastness categories.
This table is a guide for the selection of artist paints only and should not be used to extrapolate to other products. The pigment will remain unchanged for more than years of light exposure with proper mounting and display. Suitable for artistic use. The pigment will remain unchanged for 50 to years of light exposure with proper mounting and display. The pigment will remain unchanged for 15 to 50 years with proper mounting and display. The pigment begins to fade in 2 to 15 years, even with proper mounting and display.
Not suitable for artistic use. Very poor lightfastness Fugitive. The pigment begins to fade in 2 years or less of light exposure, even with proper mounting and display. Blue wool reference strip B: Megalux hours of exposure before fading becomes noticeable. Exposure to average indirect indoor lighting to lux for an average 12 hours a day equals from 0. The grey scale consists of nine pairs of non-glossy neutral grey coloured chips, which illustrate the perceived colour differences.
These are used along side the blue wool samples to determine the corresponding fastness rating as described in ISO A The problem with the blue wool scale and the grey scale is that it is a subjective test i.

Sheep will now graze grass blocks and eat grass to regain their wool, keeping the color they had before shearing.
As a counterbalance, shearing sheep will now yield wool instead of Tweaked the saturation of wool, making wool blocks slightly darker than before. Wool of any color can now be sold to farmer villagers , at 14—21 wool for 1 emerald. They also sell 1 wool for 1—2 emeralds, 1 offer for each color. Farmer villagers no longer trade wool.
