    This material study examined natural dyeing and the use of spices as colorants. Natural dyeing has a long tradition, and the roots of spice dyeing can be traced back to ancient India. As environmental awareness increases, natural and sustainable dyeing techniques are drawing growing interest as alternatives to synthetic dyes. Using spices and other natural materials in dyeing offers a way to reduce the use of chemical dyes, which may be harmful to both the environment and human health. India’s craft traditions where dyeing has been an integral part of culture and livelihood for centuries—provide valuable insights into natural dyeing methods. This study explored how these traditional dyeing techniques could be applied to the coloring of contemporary textile materials. The aim of the research was to make natural dyeing more approachable and accessible by using spices commonly available in grocery stores as dyes. A practical approach and the use of familiar materials helped lower the threshold for engaging with traditional dyeing techniques and enabled experimentation without specialized tools or hard-to-find materials. The study sought to promote the adoption of sustainable and eco-friendly dyeing methods by demonstrating how everyday, easily available food products can serve as ecological alternatives to synthetic dyes. The study was conducted as an experimental material investigation, focusing on the suitability of three different spices, turmeric, paprika, and cinnamon, for natural dyeing. Dyeing experiments were carried out on four different textile fibers: cotton, hemp, silk, and wool. This made it possible to compare how different fiber materials respond to spice-based dyes. The effect of mordanting was also examined. Three different mordanting methods were used: no mordant, alum mordant, and soy milk mordant. This allowed for an evaluation of the role of mordanting in dye adhesion and color vibrancy. Additionally, the dyeing trials were divided into two cooking temperature groups (60°C and 80–90°C) to assess the impact of temperature on dyeing results. All combinations of dye, fiber type, mordanting method, and cooking temperature were systematically documented and clearly tabulated. The diverse approach enabled the study of several variables affecting the outcome. The dyeing results showed that the properties of the spices used significantly influenced the success of the dyeing. Turmeric produced the strongest and most even tones across all fiber types, while paprika resulted in weaker and more uneven coloration than expected. Cinnamon proved to be a surprisingly effective natural dye, yielding soft, natural brown tones. Of the mordanting methods, samples mordanted with soy milk dyed almost as lightly as the unmordanted ones, whereas alum mordanting slightly enhanced the color depth. Wool absorbed color most intensely with all spices, demonstrating the generally better dye uptake of animal fibers compared to plant-based fibers. Differences in the composition of the dye baths and the unevenness of mordanting also affected the visual quality of the dyeing results, but at the same time offered opportunities to create unique and aesthetically interesting surfaces. The study showed that dyeing with spices presents an interesting and ecological alternative for textile coloration. Although the results varied depending on the spice used, the fiber material, and the mordanting method, a diverse palette of natural hues was achieved without synthetic chemicals. It would be interesting to continue this research by studying the dyeing properties of other spices and comparing the color performance of spices from different manufacturers. If spice dyeing were to be more widely adopted in the textile industry, it would also be beneficial to investigate the wash, light, and abrasion fastness of the dyed textiles.

    This empirical study developed a pink ceramic glaze using the AI-based tool ChatGPT 4o to support design and analysis. Starting from the June Perry Pink glaze recipe, modifications were made through several test series to adapt it for oxidation firing at approximately 1240 °C. The effects of tin oxide (SnO₂) and chromium oxide (Cr₂O₃) on color and surface quality were tested on white casting porcelain and stoneware clay bodies. The goal was to create a technically sound and visually appealing pink glaze, while evaluating AI's potential in glaze research. ChatGPT was especially helpful in recipe modification, Seger formula calculations, test planning, and troubleshooting. However, limitations emerged in accuracy and reliability, including the risk of confidently delivered false information (hallucination). AI suggestions required critical review and expert comparison. Ethical use of AI followed guidelines by Aalto University and the Finnish National Board on Research Integrity: AI was used as a tool, not a co-author, and its role is transparently disclosed. The most successful result was achieved with 4% tin oxide and 0.1% chromium oxide. A second series performed poorly due to chemical imbalance and incorrect material ratios. The study shows that when used responsibly and critically, AI can support ceramic research without replacing empirical testing or material expertise.
