A dye can generally be described as a colored Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue and others. Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of substance that has an affinity In chemical physics and physical chemistry, chemical affinity is the electronic property by which dissimilar chemical species are capable of forming chemical compounds. Chemical affinity can also refer to the tendency of an atom or compound to combine by chemical reaction with atoms or compounds of unlike composition to the substrate to which it is being applied. The dye is generally applied in an aqueous solution An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending to the relevant formula. The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent as well as naturally abundant, it is a ubiquitous solvent in chemistry, and may require a mordant A mordant is a substance used to set dyes on fabrics or tissue sections by forming a coordination complex with the dye which then attaches to the fabric or tissue. It may be used for dyeing fabrics, or for intensifying stains in cell or tissue preparations. A mordant is always a polyvalent metal ion. The resulting coordination complex of dye and to improve the fastness of the dye on the fiber.
Both dyes and pigments appear to be colored because they absorb some wavelengths of light Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye . In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not preferentially. In contrast with a dye, a pigment A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light generally is insoluble, and has no affinity for the substrate. Some dyes can be precipitated Precipitation is the formation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid. When the reaction occurs in a liquid, the solid formed is called the precipitate, and the liquid remaining above the solid is called the supernate. Powders derived from precipitation have also historically been with an inert salt to produce a lake pigment A lake pigment is a pigment manufactured by precipitating a dye with an inert binder, usually a metallic salt. Manufacturers and suppliers to artists and industry frequently omit the lake designation in the name. Many lake pigments are fugitive because the dyes involved are unstable when exposed to light, and based on the salt used they could be aluminum lake, calcium lake or barium lake pigments.
Dyed flax Flax (binomial name: Linum usitatissimum) is a member of the genus Linum in the family Linaceae. It is native to the region extending from the eastern Mediterranean to India and was probably first domesticated in the Fertile Crescent. This is called as Agasi/Akshi in Kannada, Jawas/Javas (जवस) or Alashi (अळशी) in Marathi. Flax was fibers have been found in the Republic of Georgia Georgia ( /ˈdʒɔrdʒə/ ; (Georgian: საქართველო, [sɑkʰɑrtʰvɛlɔ] (help·info)) is a country in the Caucasus region of Eurasia. Situated at the juncture of Eastern Europe and Western Asia, it is bounded to the west by the Black Sea, to the north by Russia, to the south by Turkey and Armenia, and to the east by Azerbaijan dated back in a prehistoric cave to 36,000 BP Before Present years is a time scale used in archaeology, geology, and other scientific disciplines to specify when events in the past occurred. Because the "present" time changes, standard practice is to use 1 January 1950 as the arbitrary origin of the age scale. For example, 1500 BP means 1500 years before 1950, that is, in the year 45.[1][2] Archaeological Archaeology or archeology (from Greek ἀρχαιολογία, archaiologia – ἀρχαῖος, arkhaīos, "ancient"; and -λογία, -logiā, "-logy") is the science and humanity that studies historical human cultures through the recovery, documentation, analysis, and interpretation of material culture and environmental evidence shows that, particularly in India India, officially the Republic of India , is a country in South Asia. It is the seventh-largest country by geographical area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the west, and the Bay of Bengal on the east, India has a coastline of 7,517 and Phoenicia Phoenicia what is now modern day Lebanon, was an ancient civilization centered in the north of ancient Canaan, with its heartland along the coastal regions of modern day Lebanon, extending to parts of Israel, Syria and Palestine. Phoenician civilization was an enterprising maritime trading culture that spread across the Mediterranean during the, dyeing Dyeing is the process of imparting colours to a textile material in loose fibre, yarn, cloth or garment form by treatment with a dye has been extensively carried out for over 5000 years. The dyes were obtained from animal Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also, vegetable The noun vegetable usually means an edible plant or part of a plant other than a sweet fruit or seed or mineral A mineral is a naturally occurring solid formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure, and specific physical properties. A rock, by comparison, is an aggregate of minerals and/or mineraloids, and need not have a specific chemical composition. Minerals range in composition origin, with no or very little processing. By far the greatest source of dyes has been from the plant kingdom Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants, known as botany, has identified about 350,000 extant species of plants, defined as seed plants, bryophytes, ferns and fern allies. As of 2004,, notably roots In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. This is not always the case, however, since a root can also be aerial or aerating (growing up above the ground or especially above water). Furthermore, a stem normally occurring below ground is not exceptional either (see rhizome). So, it is, berries The botanical definition of a berry is a fleshy fruit produced from a single ovary, such as a grape. The seeds are usually embedded in the flesh of the ovary. A plant that bears berries is said to be bacciferous, and a berry-like fruit is said to be baccate, bark Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines and shrubs. Bark refers to all the tissues outside of the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes, leaves In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat and thin. There is continued debate about whether the flatness of leaves evolved to expose the chloroplasts to more light or to increase the absorption of carbon dioxide. In either case, the adaption was made at the expense and wood Wood is an organic material, a natural composite of cellulose fibers embedded in a matrix of lignin which resists compression. In the strict sense wood is produced as secondary xylem in the stems of trees (and other woody plants). In a living tree it transfers water and nutrients to the leaves and other growing tissues, and has a support function,, but only a few have ever been used on a commercial scale.

I really like the vivd blue color, and for a first time the . dye. came out nicely. I would say for the inner splatter to do a couple things. First I would say hold the glue gun higher, so the lines are thinner, which IMO looks very nice ...
