- Indigo: Dye for the blue print
A lukewarm breeze and sunshine - the conditions for "blue-and-white" things could not be more perfect, says Joseph Koó, and ties his work apron over. 25 meters of fabric are to be dyed and then brought to dry on a leash. The weather must be friendly - and not for lounging, for which the "Blaumachen" is colloquially. Incidentally, the phrase actually comes from the profession of blueprints, more precisely, because they used to have to take breaks in the dyeing process between the individual operations.
Indigo - an expressive color
This is still the case in Joseph Koó's workshop in Burgenland south of Vienna. For the Austrian is still working traditionally with indigo. The dye from India slowly unfolds in the air when it reacts with oxygen: The cotton towels, which are drawn after the first ten-minute dive from a stone vat with indigo solution, first look yellow and then green and finally blue. The fabric has to rest for ten minutes before returning to the so-called "vat". And this alternating bath is repeated six to ten times: "Depending on how dark the blue should be," says Joseph Koó, "and so that it does not fade when washing later".
First dive: Rolled up on a star tire, the fabric is lowered
In any case, it is wonderfully clinging to his hands, as well as on the floorboards of the workshop. He grew up here - in part between museum-ready implements and fabric panels. He even remembers exactly how he perceived the smell of indigo as a child: "earthy and very own". His father taught him to dye - and his grandfather, who founded the workshop in 1921. "Blue was once the color of the poor people, and the farmers from Burgenland wore a plain blue apron in the field." The typical white patterns, which are also handmade, were only seen on festive days or in the church, because such decorated clothes were intended for special occasions.
A slow technique in fast paced times
In the 1950s, when Joseph Koó's father took over the workshop, the blueprint seemed threatened with extinction. Many factories had to close because they could no longer keep up when state-of-the-art machines were able to produce synthetic fiber textiles with all imaginable colors and decors within minutes. "With the traditional procedure, treatment with indigo alone takes four to five hours," says the blue printer, as he lowers the fabric-covered star wheel for the second time into the vat. And it is not even included in how the patterns actually come to the surface.
After ten baths, the blue has the desired tone. Next, the cardboard is washed out. He dissolves in hot water
This happens before dyeing: If cotton or linen are still snow-white, those areas are printed that will not turn blue later in the indigo bath: with a sticky, color-repellent paste, the "cardboard". "It's mostly gum arabic and clay," says Joseph Koó, adding with a grin, "But the exact recipe is as secret as that of the original Sachertorte."

Artful models serve him as a stamp. And so under his skilled hands flower after flower joins the cotton ground, which is to become a tablecloth: Press model into the cardboard, put it on the fabric and tap it hard with both fists. Then immerse again, put on, tap - until the middle surface is filled. The approaches between the individual sample lots must not be visible. "That requires a lot of sensitivity," says the experienced master of his subject, "one learns this gradually like a musical instrument". For the border of the ceiling, he chooses another model from his collection, which includes a total of 150 old and new printing blocks. Dive in, put on, knock - nothing bothers his steady rhythm.

The vats are four meters deep with their mixture of indigo, water and lime. The day before the "Blaumachen" Joseph Koó is about five liters for 25 meters of cotton added. The whole thing he stirs several times and leaves it overnight

The term "blue print" is actually misleading, because the print pattern made of cardboard looks green and keeps the white underneath in the indigo bath - it "reserves" so to speak, which is why the process is also called "reserve pressure". Before dyeing, the cardboard has to dry for three weeks - for this the fabrics come on a leash

Meterware is not printed with models, but with rollers on a machine that came in 1936 as a vintage car in the workshop. It is probably the last hand-operated model that is still in operation
Bags and dresses made of blue-printed fabric are again very popular today
When the blueprint came in Europe in the 16th century, elaborately embroidered and woven fabrics were in vogue. The blue print, on the other hand, received the reputation of poor people art. Its spread in the 18th and 19th centuries, he owes to the fact that the journeymen then went to the Walz. To date, only a few workshops have survived - but in times when manual labor is valued again, blueprints turn into upmarket goods. You will find the Koła Blauddruckerei in Neugasse 14, A-7453 Steinberg (Austria).
Indigo: Dye for the blue print
Before one could artificially create colors, one painted and colored ones with plants. Blue fabrics used to be produced with the help of the dyer's wool (Isatis tinctoria). The dye of the yellow-flowering, up to 120 centimeters high, two-year-old plants is contained in the leaves and is dissolved with alcohol and salt. Pickled fabrics first turn yellow-brown. Only when drying outdoors they are blue by sunlight and oxygen. A deeper blue produces indigo, a dye that can be obtained from the eponymous indigo plant (Indigofera tinctoria). The extraction of the plant dye from the indigo plant can be detected until ancient times. Indigo was still rare in Europe until the 12th century, with smaller quantities being imported from India. Today Indigo is cultivated in Brazil and El Salvador.
