It is often importance to control the temperature of the dye bath. As I had broken my digital thermometer this week I bought a replacement . Just a simple sugar thermometer this time.
I used it to keep the temperature of my onion bath at around 80 oC . This worked well . I was pleased. Then I left the thermometer standing in the pan whilst everything soaked for about 24 hours. Perhaps this was a mistake.
Look at these spots . I can only think these are iron contamination. I have dyed many times with onions skins and never seen anything like this before. These are test pieces so it’s not the end of the world , but it yet another reminder of the care that is needed when using natural dyes. Change nothing !! Easy to say , but really quite hard to do .
On my small vessel there seem to be no spots I am quite pleased with it , and maybe the spots on the bracelets , can be considered part of the design. Well maybe !
