We have found lots of resources that show us how to make dyes from vegetables, fruit and other sources of vegetation.
So ..... we experimented!
Today we have chopped up purple cabbage we have to boil it in water for about an hour then strain it.
This is meant to make a blue coloured dye.
We could see colour on the knife it looked like it was going to be purple. So we put it onto some paper to see if it would stay purple or change. We noticed that it turned blue as it dried. We also noticed that bits of cabbage left on the chopping board changed to blue too.
When we started to boil the cabbage we were able to see the water changing colour really quickly. We tested it on paper and it made light blue.
After boiling for longer we got a very dark blue dye.
We stored this dye for a week in a dark cupboard. When we got it out today (Monday 26th Aug) we found that it had changed colour again, to a reddie purple.
We are going to try dying some fabric and see what colour it stays.
While we were dying the fabric we decided to try different mordants.
No Mordant We tired - Salt We tried - Soda Ash
We now know that mordants have an effect on the colour of the dye.
