The river red gums are shedding bark all over my city. I was riding down to visit my parents passing a planting of these trees along the railway corridor near Marion station. I couldn’t resist, so pulled over and took pictures and bark. Under these trees, the ground is covered with thousands of tiny gumnuts (as well as bark).
So of course, I collected some bark just to try it out… and yes, tan again. Brown, with alum. Often I can see almost no difference between wool with no mordant and wool with alum after dyeing, but this was a clear example of alum making a difference.
