An easy dye-pot from dried leaves of Persicaria tinctoria

Michel Garcia is proposing here a simple manner to use a handful of leaves of persicaria indigo plant to get a blue dye on silk fabric.

Thank you ! You are the science teacher everyone wishes they had, and or have in school ! You are truly gifted, and know how explain and teach concepts that are hard to grasp and master. Looking forward to future content you post. This is the clearest explanation of the science involving indigo's chemical changes in each stage.

Thank you so much. your comment is very encouraging for me I am actually travelling, but planning short sequences to edit here

Thank you so much for posting this. I could listen to you for hours, such clear instructions and explanations, you make it so interesting. I am going to dry some indigo leaves to try this.

Excellent video thank you!

[@anniesprague9058]

Thank you so much for sharing this video. I found it super helpful.

[@TerrifiedTito]

This is so so helpful!! Thank you! I see you’re doing this indoors - is it safe to make a larger vat (like a big cooking pot) and cook it on the stove indoors? Is there any risk with inhaling the vapors? Also, you’re using glass - can this also be done in a metal pot?

[@michelgarcia640]

A Metal pot is appropriate. At much bigger scale trere are other processes much preferred, such as compost vat or indigo vat, however, a 10 to 20 liters vat is still OK. About vapors, there is nothing toxic in the plants and ingredients. No solvant

Hi, thank you for sharing, a question, what is the first powder you are adding? I cannot understand! Thank you!

[@JAsisterti]

thank you Michel - ! I love. your approaches :) I'm trying to figure out the streaming version of your videos - any tips

Thanks you Michel for sharing this extremely interesting video and your knowledge! I very much look forward to more! Merci!

This is interesting, thank you very much!

When you put the beaker into the pot. What is in the pot. Cool water?

[@Mega3penguins]

What are the portions?

[@bernadettepuleo]

Do you add warm water?

[@michelgarcia640]

Hot water is better

Solution soda ash is Na₂CO₃ o carbonato de sodio?

[@michelgarcia640]

si esta carbonato de sodio

Which type of lime do you use here ?

[@michelgarcia640]

This is quick lime, however I did experiment also with slaked lime. The most important being that the slaked lime must be extremely well preserved from the humidity of the air. Living in Brittany, I "solved" the problem by using quick lime, which is far less sensitive to humidity

[@ginaveda1782]

@@michelgarcia640 Thank you. So, you mean CaO. If I use slaked lime (Calcium hydroxide instead Ca(OH) 2 ) would it be in the same proportions ?

[@michelgarcia640]

@@ginaveda1782 the most important is to join lime and potassium carbonate from ashes solution. I did test the slaked lime and it worked; il might be that one need more than a pinch. The demo which is presented here is not really a recipe, this is part of a moovie from Olga Kazanskaia, which offrered this sequence, the whole film being available in few monthes. The idea will be to show "how natural dyes works" , so the question "how much shall I put in" is not the crucial point: I remember when I did propose the indigo vat that I called 1-2-3, based on proportions of indigo, lime and fructose: Lots of people did complain that they were following "acurately" the proportions and did not get satisfaction. Of course it came mostly from the quality of their lime, which, if a bit old, is far less efficient than a newly-made one.
