Sourgrass, the Awesome Dye – As “Flores Amarelas”

September 22, 2016

Já tinha feito o teste há uns anos e tinha ficado muito impressionada com a cor da “erva-azeda” – ou “flores amarelas do quintal”, que é um nome um bocadinho mais agradável. Este ano levei a coisa mais a sério. Pedi que me apanhassem as flores durante o inverno, para as conservar secas. Este verão foi só pô-las de molho ao sol e voilá, um taça de cor. Mas a coisa mais incrível foi a persistência do pigmento. Normalmente, com outras plantas, a primeira e segunda panela de lã que é tingida fica com cor. Mas o pigmento depois torna-se demasiado fraco. Estas flores, pelo contrário, mantiveram a mesma intensidade de cor durante 6 panelas! Agora estou a testar a resistência da cor à luz, numa experiência caseira.

I tested sourgrass, for the first time, years ago and I was pleasantly surprised. This summer I did a proper dye bath with it. I asked my fmaily to pick these yellow from our backyard during the winter and they were preserved dry. In the summer, I soaked them in water under the sun for a day – and I got a perfect solar dyebath. The most incredible thing was the persistence of colour through several dips. Usually, after the second or third dip, the batches of wool come out of the dyebath with only a faded tint. But these flowers maintained almost the same intensity for 6 whole batches of mordanted fiber! Now I am testing whether they are light fast with a homemade experiment.

 

 

Depois de 6 panelas de lã (cada uma  com mais de 100 g), o resultado continua lindo. A fotografia abaixo mostra a 6ª panela, à sombra, ainda bem amarelinha.

After 6 batches of wool (each over 100 g), the result is still beautiful. The image below shows the 6th batch drying in the shade, still bright yellow.

    Quem diria que as azedas servem também para isto. Linda cor!

      Thanks! I have a really good feeling about this one. I haven’t worn anything I dyed with these flowers (usually my preferred test method) but a skein I dyed years ago and stored away looks pristine.
