RØD! / RED!

Tænkte at jeg over det næste stykke tid ville lægge lidt billeder ud af de ting, jeg har farvet.
Jeg har for nyligt farvet en rigtig god rød på hvidt uldstof med krap, den blev faktisk Danneborgsfarvet. Det bliver til en varm vikingekjole.

(ja, det er min hånd, jeg kunne ikke lade være ;)

Jeg holdt temperaturen på 65-70 C i farveperioden for at undgå de gule nuancer fra krappen, og lod det derefter køle af ca. 4 timer i farvebadet. Jeg farvede også noget hvidt, mellemgråt og mørkegråt garn i farvebadet og farverne blev meget interessante.


Jeg har siddet og læst en del om krapfarvning og det viser sig at krap farver bedre rød hvis badet er lidt alkalisk, mens farven bliver mere orangerød hvis badet er surere. Det er jo væsentligt i Danmark, hvor vandet (groft sagt) er mere kalkholdigt jo længere østpå man kommer.

I thought I would post some of the pictures I have of stuff I've been dyeing recently.
I'm so pleased with the result of this madder-dyeing, (picture 1), it's brigth red - Lego block red. I'll make a varm dress to use at re-enactment events with it.

I also dyed some white, some pale grey and som dark grey yarn in the same bath, and I really like the colours (picture 2).

I kept the temperature at no higher than 65-70 C (149-158 F) the course of the dye period to avoid getting the yellow colours from the madder. Then I let the fabric and the yarn cool for about 4 hours in the dye-pot. I could have left them there overnight, but I needed the pot for another dyeing.

I've been doing some reading about krap, and realized that the acidity of the water means more in madderdying than I thought.
The Danish underground is very rich in calcium, as Denmark is mostly on old seabed (pray for us if the global warmning increases, oh oh) there shouldn't be any difficulties in getting god reds, but it's nice to know...and it makes me want to try an acidic bad to see what colour I would get.

Very lovely red, Saga! My water is quite acidic (pH 6) and I always get orange/peach colours instead of true red with madder. Even when I add things to make it more alkaline. I get purples instead of red with cochineal too! A proportion of each seems to be the only way I can get real reds.

Thank you.
I'm actually not talking pH here, but dH: How "soft" or "hard" the water is. Hard water gives better reds.
Also remember that temperatures above 70-75 C will give a more orange colour.
