Material Science: Beginners Guide to Natural Dyes

Average rating:4.8Number of reviews:(1,561)
In this course, students will be introduced to the natural dying process for wool yarn.
Class experience
Naturally dyes are how all cloth was originally colored - using roots, bark, flowers, insects, and vegetables. Even though the process takes longer and results cannot always be predicted, this method allows you to produce your own unique fabrics and yarns. Once you get the hang of the chemistry you can get brighter or more subtle colors in your projects. We will be going over the four types of dyes: substantive, adjective, vat, and fugitive. Each student will be able to choose their own dye...
Students will improve their understanding of the chemistry that goes into dying fabrics and yarns as well as how to manipulate this chemistry to achieve the colors they desire. Processes covered in this course: - Scouring Process - Mordant Process - Dye Extraction/Dye Bath - Hot Dyeing Method - Modifiers
I have always been a crafty person. Working around sheep for years definitely honed my wool-processing skills. It also helps that I have a minor in chemistry.
1 file available upon enrollmentA natural dye ingredient (choose from the following): - avocado skins and pits (light pink) - tumeric powder (yellow or orange) - hibiscus tea (bright pink) - red cabbage (blue) - black bean with baking soda (green) - black bean (blue) - basic rule to how much is needed is a 1:1 to 3:1 ratio of dye ingredient to wool weights (ex: if I have 3.5 oz. (100 g) of yarn I would want anywhere between 100 to 300 g of dying ingredient.) - any ingredient like the avocado skins and pits can be stored in the refrigerator Mordant agent: Allum powder is my choice (you can get 1.5 lbs for $10) Pot (whatever you use, you can never use it to cook again!) Stirring wooden spoon (again, this will be set aside for crafting only) Strainer (this is okay to use again if rinsed very well) Neutral pH soap (a mild dish soap is okay) Cream of tartar Vinegar (1 bottle) Baking soda (1 container) Heat source (like stove top) Gallon Ziploc bags (optional method) Plastic bowl/container (not to be used for food) The wool you are going to process (make sure that it is 100% natural or it will not dye correctly) Rubber Gloves Written instructions will be provided on the first day of class for the complete process.
Learners will not need to use any apps or websites beyond the standard Outschool tools.
This course will require adult supervision as we will be boiling ingredients and working with Aluminum Sulfate (safest option, but still should use caution)
