Green dye from Black Turtle Bean

Following on from the previous post about black bean dye –

The next day, bicarbonate of soda was added to the Black Turtle Bean solar dye.  Colour changed to green and this colour transferred to the un-mordanted silk and cotton scraps.

This test needs to be redone; the bicarb was added to the original dye which was probably a bit tired – the beans were ‘going off’ at the time.

I also added to the solar dye pot some rolled-up paper, but the green disappeared into a brown-green when applied to paper.   Something in the paper which is photocopy paper reacting with this dye.  Where the pools of dye were deeper the green colour is just apparent.  This paper is stuck onto the test page and covered the swatches in the above image, hence the change of page direction!

Black Turtle Bean, dye

Saw Grackleandsun‘s blog on black bean dyeing, so I thought I would add this information on my recent test.  I used Black Turtle beans – not sure if these are the ones used in dyeing by Grackleandsun, but according to Wikipedia – “Black turtle bean is a small, shiny variety of common beans (Phaseolus vulgaris), especially popular in Latin American cuisine, though it can also be found in Cajun and Creole cuisines of south Louisiana. They are often called simply black beans.”

I coloured mordanted cotton and non-mordanted silk and also used the dye straight from the solar dye pot on the page.  it gave a lovely colour.  Eventually the jar did rather pong!

Anyway, here’s the page from my test book;
