Description

METHOD OF PRODUCING WHITE DYE FROM MUSSEL SHELLS Technical Area This invention utilizes mussel mother-of-pearl in a process that is free from harmful chemicals. A white material that can be applied to paper and provides complete coverage on the surface it is applied to. It relates to the dye production method. Previous Technique Natural dye making existed in the past, but today it has been replaced by industrial dyes. It is one of the techniques. In sources that have reached us from the past with limited recipes, ink... Apart from the production process, sufficient information about watercolor painting using natural dyes and traditional methods. It is not available. Natural dyes are frequently used in yarn dyeing today. Coloring appears to be limited to areas where it can be applied with a brush. The production of natural pigments and dyes has been carried out using traditional methods in many cultures throughout history. It has been made since ancient times using lime, lead carbonate, chalk, and egg white. Plant extracts were used to obtain white dye. However, like lead oxide (white lead), Due to their toxic properties, the use of these substances is prohibited today. The color white... Another common source in industry, titanium dioxide (TiO₂), also poses environmental and biological risks. Due to the risks, it is restricted in many countries. This situation necessitates the use of non-toxic, natural products. This has increased interest in white pigments derived from natural sources. Today, industrial paints use chemical solvents, synthetic binders, and opacity enhancers. Because it contains additives, it can have negative effects on both human health and the environment. This opens up. In contrast, the natural dyeing methods described in the literature are mostly single-use. It produces colored, low-strength results or results unsuitable for industrial use. It also has a natural white tone and can be used in watercolor or primer form. Detailed formulation of a paint composition with opaque properties has not been studied. Document EP2062560A2 describes the coloring of raw materials used in dental prosthetics. Jasper powder, coral powder, or mussel powder are used in the process. The powdered form... from the coloring process and effectiveness of mussels mixed into the raw material It has been mentioned. 1 Document number 2022 / 007144 discusses the use of the yellow color of the turmeric plant for dyeing. The processes involved in transforming it into a tangible form and its effectiveness have been discussed. Purposes of the Invention The aim of this invention is to eliminate the harmful and chemical processes involved in the use of mussel shells. It does not contain any pigment, can be applied to paper, and provides complete coverage on the surface it is applied to. The goal is to improve the production of white dye substances. Furthermore, the invention recycles waste mussel shells using entirely naturally sourced raw materials. to achieve this transformation, thereby both reducing environmental pollution and promoting sustainability. It aims to contribute to material production. Detailed Description of the Invention The subject of the invention is the production of white dye. - Mussel shells are placed in a mortar and pestle and ground into powder by pounding. - mixing water with the resulting mussel powder, - The powdered mussels mixed with water are strained through cheesecloth. - evaporation of the filtered water, - Obtaining the powdered dye remaining at the bottom after the evaporation process, - adding gum arabic as a binder to the resulting powdered dye, - Powdered pigment and gum arabic are ground for 1 hour to obtain the desired paint consistency. The process involves the following steps. 50-100 grams of waste mussel shells obtained from the sea or the food industry, They are cleaned to remove any organic residue. This process, It is made by washing the shells with water and drying them. Cleaned and dried. The husks are prepared for grinding. The dried husks are crushed into small pieces using a mortar and pestle or grinder. They are separated. The shells are added to the mortar in a 1 / 3 ratio. The purpose of this step is to remove the shell. to increase the surface area of ​​the mother-of-pearl layer inside and in subsequent stages to make contact with water To make it easier. 2 Water is added to the resulting mussel powder in a ratio of 1 / 3, and the mixture is homogenized. This... In this step, the water does not dissolve the shell powder, but rather separates the mother-of-pearl layer within it. and allows fine particles to pass into the water. Mussel powder mixed with water is filtered through a fine-mesh cheesecloth. This process removes large mussels. separating the particles and obtaining filtered water containing purer, finer white pigment. It enables it to be done. The filtered water is then evaporated using a slow evaporation method (for example, at room temperature or low temperature). (by being left to stand) the water evaporates. When the water evaporates, a thin, white sediment remains at the bottom of the container. It is formed. This sediment is a white pigment derived from mussel nacre. 50-100 grams of powdered pigment. It is placed on a marble slab. The resulting dry powder pigment is mixed with 10-20 grams of gum arabic, a natural binder. It is mixed with gum arabic. Gum arabic helps the pigment particles stay together and adhere to the surface. It ensures that it adheres and doesn't crack after drying. The pigment-binder mixture should be stirred for approximately 1 hour until a homogeneous consistency is achieved. It is crushed or mixed throughout. During this process, the density of the mixture is adjusted; if necessary, less is added. The desired paint consistency is achieved by adding the appropriate amount of water. The resulting mixture is in the form of a white paint that can be used directly. This paint can be used on paper, It can be applied to surfaces such as wood, canvas, or ceramics. Once dry, it completely covers the surface. It provides coverage, gives a matte white finish, and is environmentally friendly because it contains no chemical ingredients. It does not harm the user. 3
