Eco printing throughout the year – August

Today I’m comparing prints from my rusty roasting tin with prints made in a new roasting tin.

If you want to see my eco printing posts for the rest of the year type “Ecoprinting throughout the year” into the search box.


Pot – Boil 1 – Rusty roasting tin, boil 2 – new roasting tin.

Water – Tap water with vinegar.

Paper – watercolour and cartridge papers

Mordant – alum acetate

Leaf dip – rust water

Plants – Cranesbill geranium, coeopsis, eucalyptus, fern, cotinus.

Cooking time – 45 minutes, turned, 45 minutes.

Blanket -none.


Boil 1. – Images are dark due to the pan being very rusty.

Boil 2. – Images are lighter as the only iron present was the liquid used to dip the flowers and foliage.


Left print rusty pan, right print new pan.

Conclusion – Prints using the rusty roasting tin are much darker than the ones in the new roasting tin. Also I think the tiles that I use are so impregnated with iron they are making the prints darker. I need to use new tiles for very light prints. I like the stronger tonal values, the cotinus leaves came out out very dark and the eucalyptus printed well, you can even see the stoma on the leaf prints.
