4. BioChromes¶
Notes
=> living color
=> any pigment produced by a living organism
=> it has de ability of changing
=> Bc resources: botanica - bacteria - fungi - insects and molusks - mineral
Research¶
I've started investigating and working with Biochromes a few years ago in BsAs, extracting pigments for ink and cosmetic purposes, but mostly dyes wich I incorporated in some art textiles pieces.

Recipies and dyeing process¶
Yerba MATE¶
Ilex paraguariensis
Yerba mate is a native plant from south america, and its leaves are use to prepare a every day beverage, really tradicional in Argentina, Uruguay, Paraguay and south of Brazil. I chose to work with this plant because its my every day "waste" and fortunatly has dyeing properties. I´ve been saving and dehidrating the herb since my first day in Fabricademy at the BDC.
Dye¶
- Dyeing material: 300 gr yerba mate
- Fabric: 44gr (linen, cotton, wool, silk, bamboo, felt)
- Water: 2 lts
- Boil the herb for 30 to 60 mins => filter inmediatly cause mate stars reabsorving the dye
- Boil for 30 mins with fabrics and leave to rest for some hours so that absorbs as much color as it can
- Once its dry iron the textile - it will help to fix the color
Results
Color palette¶
Experimentation with diferent vegetables + cochinilla to created our color palette at the BDC.
Recipies
115 gr **onion skins**
112 gr fabric
2,25 l water
184 gr **eucalyptus bark**
112 gr fabric
2,25 l water
300 gr **yerba mate**
112 gr fabric
2,25 l water
4.6 gr **cochinilla powder**
44 gr fabric
2,25 l water
245 gr **avocado pits**
44 gr
1 l water
Final results
INK¶
For the ink we boiled some dye bath until we obtained 100ml of liquid => we used a recipe that ive learned from Luciana Marrone
=> 100 ml of dye bath + 1 gr guar gum => mix it till it gets to a nice and thick consistency
=> add 1 drop of rosemary esencial oil as a natural conservant
Yerba Mate
- Ingredient: 41 g
- Water: 1 l
- Reduce to 100 ml
- Mix with 1 g guar gum
Hibiscus
- Ingredient: 34 g
- Water: 1 l
- Reduce to 100 ml
- Mix with 1 g guar gum
Turmeric
- Ingredient: 20 g
- Water: 1 l
- Reduce to 100 ml
- Mix with 1 g guar gum
=> the inks lacked of some consistence for stamping, and a little transparent too => we added some "blanco españa" (white pigment that has some carbonate calcium) + magnesium stearate
Stamp + Print¶
We decided to create a stamp using the modul of last week assigment with linoleo and the laser cut, to print some totebags and use our fresh inks. I was curious to see what a tanin bath would do to my fabric so I soak the totebag in it, althought the colour of the ink didnt change much the fabric got brownish.
Final result
𖦹 Notes & thoughs 𖦹¶
- Each material dye has its own particularities when it come to extracting color
- Leaving the textiles resting for hours, even days, gives very nice colours
- I very interested in making inks for textil and printting
