I've bought some logwood bark from Wollknoll (1 kg = 15 EUR) and of course had to test it immediatelly. here I would like to show what you get if you use 40 gr of bark with 1.5 litle of ordinary water. I soaked the bark overnight and then simmered it for approx. half an hour. I soaked a piece of silk in it and got very nice rusty colour (the sample on the top). Then I took the same dyed rusty coloured piece and made three samples which I soaked in three different mordants (post mordanting) I used alum, vinegar and washing soda. This is what I got:  . Alum yields very beautiful dark violet colour, vinegar turns the colour into golden yellow and soda changes the colour into bluish black. Since i had plenty of dye left I dyed a silk scarf in it but diluted the solution because I wanted pale violet. I liked the colour and decided to nuno felt at scarf. You can see the result here.  I love this dye it gives so many different beyutiful colours. There will be more experimenting in the future, this one kilogram will last very long. |

WOW! That's beautiful. I'm not a dyer (yet - you're inspiring me!), so let me make sure I understand what you did. You dyed one piece of fabric, then put pieces of it in mordants AFTER dying? I thought the whole purpose of mordanting was to prepare the fabric to take up the dyes.
Do you have any idea what would happen if you mordanted first?

Elisabeth, yes, I put pieces in mordants after dyeing silk. This is called post mordanting. I don't know what would happen if I mordanted the silk and the solution first. I need to experiment on it.

Fantastic results Nada! I admired the scarf on Facebook and liked to see more information. Thank you very much!

Those are all beautiful colors and the scarf is gorgeous. Look forward to more experiments to see if pre mordants are any different than post mordants.

Great results. I think that is what a friend of mine was experimenting with a few years ago she had sawdust from a bow maker. I think she soaked the saw dust with different things. vinegar and soda ash. one to get red and one for purple.

Lovely colours here Nada. Logwood is on my wish list, but don't know if Santa has spotted it!

I thought the whole purpose of mordanting was to prepare the fabric to take up the dyes. Do you have any idea what would happen if you mordanted first? A mordant is used before dyeing, to encourage the fibres to grab the dye and also to aid colour and light fastness. Alum, copper, tannin, oxalic acid (which comes from rhubarb leaves) are mordants, though they can be used as modifiers too. Vinegar is not a mordant but can be used as an acid modifier. Alkaline modifiers can be used too e.g. Ammonia or Sodium Carbonate. When used after dyeing, they are know as modifiers. Using before or after the dyebath will create different results. |

I posted a blog back in May of this year where I used all natural plants for dyeing silk and wool. Logwood was one of them. You can find the blog here:

Sorry I don’t know how to send the actual link, but I found it by searching “logwood dye” on the Studio Forum. Took two seconds.

I remember the post Cathy.
Some are using plant prints over a logwood dye, which gives a wonderful discharging effect. I'm aiming to try it in Spring when the foliage returns.

Judith, I have never tried the plant printing over logwood, but now that’s a new idea for the Spring!
Ruth, thanks for posting the link for my dyeing with plants!

I can't wait for Spring and the reawakening of all those wonderful plants. My intention is to freeze some next year so I'll still have something to play with next winter. Note this is my intention and you know what they say about the road to Hell.   |
