When Did People Start Wearing Black Clothes?
I’ve been going nuts trying to work out if Istvan’s outfit is realistic or not, not least because nobody else seems to wear anything like it (closest is Hanush with his bumblebee outfit). Anyway it turns out I can unclench because black clothing was starting to become relatively inexpensive/easy to access by 1403, though now ofc I’m agitating about the gold trim.
TNT (trinitrotoluene) was first synthesized in 1863 by the German organic chemist Julius Wilbrand, but not as an explosive. He was working on yellow dyes useful for wool & cotton fabrics, uniform trim, decorative ribbons & upholstery textiles. TNT fit the bill because it formed bright yellow crystals and looked like a dye that didn’t explode like other nitro compounds. It took another 28 years before chemist Carl Haussaermann revisited the yellow dye with strong detonators, better nitration control, & a growing military interest in stable, melt-castable explosives. He recognized that TNT’s low sensitivity and high energy content made it ideal for shells & artillery. TNT’s explosive significance became globally obvious after WWI.

Bright colors still dominate U.S. foods, but scientists warn the dyes behind them may come at a cost. Almost one in five packaged foods and drinks available in U.S. grocery stores contain synthetic food dyes, according to a new analysis of 39,763 products. The research was recently published in the Journal of the Academy of […]

As the global fashion industry grapples with the urgent need for sustainability, the textile sector in Bangladesh is at the forefront of this transformation. Known for its vibrant colors and rich cultural history, Bangladesh is increasingly becoming a hub for green textiles, characterized by the use of natural dyes and sustainable fabrics. In this article, we explore the significance of green…
Green Textiles: Exploring Natural Dyes and Sustainable Fabrics in Bangladesh
ALTDyes like Congo red and methyl orange create brightly hued shirts, sweaters and dresses. But these commonly used azo dyes can be toxic, carcinogenic and are hard to remove from wastewater.
David Chem, a University of Arkansas chemical engineering Ph.D. candidate, developed an environmentally friendly solution to remove these dyes using a common byproduct of the pulp and paper industry.
Azo dyes are used in 60%–70% of commercial textile production. The dyes dissolve easily in water and resist biodegradation, which makes them an environmental hazard. The runoff from garment plants has the highest concentration of azo dyes, but they also end up in municipal wastewater from washing clothes.
I did a dye with Echinodontium tinctorium after soaking it for 2.5 months in a basic solution. I did not get as dark of color as expected, but I did get color! Next time I will have to break the fungus down more and then see of that helps, the dyebath is going to be laked, filtered and then dried and stored for later use in pigment making.
Campbell’s announced it will eliminate synthetic food dyes from all its products by the second half of 2026, replacing them with colors from natural sources.
The change will affect popular items including Lance crackers, V8 Splash, and regional snack brands, which will soon use ingredients like annatto and purple carrot juice concentrate.
The move follows shifting consumer demand for simpler,…

Black plastics are widely used in industries from packaging to electronics, but most of them never get recycled. The reason is simple conventional black pigments absorb the near-infrared (NIR) light used in sorting systems, making these materials invisible to automated recycling technology.
At Rathi Dye Chem, we are committed to promoting solutions that make recycling more efficient and sustainable. Together, we can turn a recycling challenge into an opportunity for a cleaner future.

Plastics are one of the largest sources of pollution on Earth, lasting for years on land or in water. But a new type of brilliantly colored cellulose-based plastic detailed in ACS Nano could change that. By adding citric acid and squid ink to a cellulose-based polymer, researchers created a variety of structurally colored plastics that were comparable in strength to traditional plastics, but made…
ALTSodium chlorate (NaClO₃) is a highly oxidizing chemical compound primarily used in the paper and pulp industry for bleaching processes. Additionally, it serves as a precursor in the production of chlorine dioxide and finds applications in herbicides, dyes, and explosives. With its growing demand in industrial applications, understanding the Sodium Chlorate Production Cost becomes essential for stakeholders, manufacturers, and procurement managers to optimize operations, evaluate feasibility, and forecast investments.
Procurement Resource, a trusted market intelligence and cost analysis platform, offers a comprehensive Sodium Chlorate Production Cost Analysis Report that presents detailed insights into the economic and technical aspects of the manufacturing process. This report is an indispensable tool for strategic decision-making, guiding businesses through cost modeling, raw material sourcing, and operational planning.
Sodium chlorate is a white crystalline powder or granular solid, easily soluble in water. Industrially, it is chiefly used as an oxidizing agent. The compound is favored for producing chlorine dioxide for bleaching wood pulp — a process that enhances brightness and reduces environmental damage compared to traditional chlorine bleaching.
The Sodium Chlorate Production Cost structure is influenced by several dynamic factors. Procurement Resource’s analysis identifies and breaks down these components to give a granular understanding of expenditure heads including capital investment, raw materials, utilities, and labor.
The cost model is structured to cover both direct and indirect costs:
Each cost center is calculated based on the plant capacity, process route, regional economic conditions, and technology deployment.
A pre-feasibility analysis evaluates the early-stage economic viability of the sodium chlorate manufacturing project. It includes:
Feasibility studies further explore ROI projections, break-even analysis, and payback periods under different market scenarios.
The industrial production of sodium chlorate mainly involves the electrolysis of sodium chloride (NaCl) in aqueous solution. This process occurs in a specially designed electrochemical cell.
Electricity represents a major chunk of operational costs due to the energy-intensive electrolysis process. Costs can vary significantly across geographies, making it a crucial factor in site selection and cost modeling.
Utility Costs Include:
The labor component in the Sodium Chlorate Production Cost is categorized by:
Labor costs differ based on location, labor laws, and skill availability. Automated plants may reduce headcount but increase capital expenses.
Logistics and supply chain considerations significantly affect the production cost and final price of sodium chlorate. Key components include:
Optimizing logistics, such as sourcing salt locally or choosing energy-efficient locations, can lead to significant cost savings.
Several industry trends are shaping sodium chlorate production economics:
These trends emphasize the need for continuous monitoring of input prices and technological advancements to stay competitive.
