This scarf is a gift for my uncle, inspired by quartz clusters we saw together backpacking in Cottonwood Canyon in Death Valley. From what I've been reading I think they were formed by intrusive igneous rock forming around xenoliths, and by cooling very slowly forming the incredible quartz crystals we saw, which looked like rings around the darker xenoliths in the weathered rock face we saw. I'm not trained as a geologist though and would love to find more information about the geology of Cottonwood Canyon from someone with some real expertise!
The wool is targhee roving I got at the nor cal ren faire. I spun it on my small cross arm spindle and wove it on a loom I've been borrowing from a friend. It's plain weave set at 8epi. It looked very open on the loom, but fulled into a wonderfully bouncy and dense fabric.
After fulling I scoured the fabric, then used rubber bands to do this shibori inspired dye process. After putting on the rubber bands I gave it a bath in tannins I extracted from an oak gall, then in a bath of cool water with just a tiny bit of dissolved ferrous sulfate. It was so exciting to see the fabric turn grey in a a matter of just a few minutes when I put it in the iron bath!

A fascinating wander through #history - everything from Byzantine tombs to WW2 - via the #chemistry of my favourite #colour - #purple. There's a lot of #literature and #music along the way as well as insight into the personalities behind the history and science. Filled with links that lead to so many byways to get lost in! And some serious chemistry right at the end. The journey is well worth taking.
I might happen to know the author, @keiran_rowell 😘

The many uses of Broomcorn (Sorghum): "..In Nigeria, the pulverized red leaf-sheaths of sorghum have been used to dye leather, while in Algeria, sorghum has been used to dye wool. In India, the panicle stalks are used as bristles for brooms."

21 Garden Plants to Use as Natural Dyes
You’ve heard of vegetable and cut flower gardens, but what about dye gardens? Dying yarn and fabrics with plant-based dyes allows you to create beautiful hues and develop a new appreciation for plants. If you’re not sure where to get started, join Briana Yablonski to learn 21 plants you can use as natural dyes.
Written by Briana Yablonski Horticulture review by Sarah Jay Last updated: May 1, 2024
"very so often, a new question strikes me. A few years ago, I found myself wondering how people transformed neutral-colored wool, cotton, and silk into shades of pink, blue, and yellow. I knew I could find synthetic dyes in tie-dye kits and commercial clothing factories, but I wondered how people colored their clothing, rugs, and linens before these products existed. Amazingly, many natural plant dyes can be grown right in our home gardens!
While not all natural dyes come from plants, there are more than a handful of flowers, leaves, and fruit that offer beautiful colors. Since dyeing is a chemical process strongly affected by pH, adding materials like soda and citric acid allows you to use one dye source to create multiple colors.
You’re welcome to experiment with natural plant dyes of any species, but some plants are known to produce particularly vibrant colors. Try dyeing with a few of the following plants to see the range of colors the botanical world offers."

How to Make #NaturalDyes in Every Color: A Step-by-Step Guide
Grace Waters - December 31, 2023
Excerpt: "Which Ingredients Will Make Which Colors?
You can use practically any plant, produce or spice to make a natural dye. Many of those ingredients are available year-round. Here’s how to make natural dyes with every color under the rainbow.
Red
Produce like raspberries, cherries, cranberries, and pokeberries will make rich dyes. You can also use hibiscus, rose, amaranth, and hollyhock plants. Most deeply red flower petals will produce saturated pigments. Beetroots will make a pink dye that is incredibly vibrant.
Orange
The flower calendula makes for a fantastic natural orange dye. To get that classic, bright color, use carrots or orange peels. Surprisingly, pomegranates can also produce deep orange hues.
Yellow
Tumeric is incredibly vibrant and easily stains. Ginger is another good spice, but it isn’t as bright. Flowers like goldenrod, yarrow, black-eyed Susan, and dandelions produce varying shades of yellow. You can also use lemon peels.
Green
You can use almost any plant’s stems and leaves to make a vibrant green color. Leafy greens like spinach also work well. If you want a very bright shade, you may have to add some blue.
Indigo
Blue flowers like bachelor buttons and Russian sage will create unique, rich hues. Of course, you can also use blueberries for a very dark dye. Red cabbage makes a classic, bright purple color. If you want something more saturated and subtle, use blackberries.
Brown
Red onion skin and #acorns can make light brown or tan dyes. If you want something darker, use #BlackWalnuts or used coffee beans."

Native Plant Dyes
"Plants have been used for natural dyeing since before recorded history. The staining properties of plants were noted by humans and have been used to obtain and retain these colors from plants throughout history. Native plants and their resultant dyes have been used to enhance people's lives through decoration of animal skins, fabrics, crafts, hair, and even their bodies.
"Types of Dyes
"Natural dye materials that produce durable, strong colors and do not require the addition of other substances to obtain the desired outcome are called substantive or direct dyes. Sumac (Rhus spp.) and walnut (Juglans spp.) are native plant examples of direct dyes. Because these species are high in tannic acid, they do not require additional substances to be added for the dye to attach to fibers and form a durable bond. Dyes that need this type of assistance are called adjective or mordant dyes.
"Mordants
"Mordants are water-soluble chemicals, usually metallic salts, which create a bond between dye and fiber thus increasing the adherence of various dyes to the item being dyed. The actual color one gets from a natural dye depends not only on the source of the dye but also on the mordant, and the item being dyed.
"Most mordant recipes also call for the addition of cream of tartar or tartaric acid. Use of this readily available spice is important because it reduces fiber stiffness that can occur because of mordanting. It can also increase brightness."

Viability PCR (Microbiology 🦠)
Viability PCR, also named v-PCR or vPCR, is an evolution of PCR. Through the use of a simple pre-treatment of the sample by the means of specific intercalating photo-reactive reagents it's possible to neutralize the DNA of dead cells. As a result, only DNA from live cells will be detected by PCR. This approach expands a lot the analytical scope of PCR procedures.
