Abstract

Luster is a thin film layer that forms on the glaze surface when metal ions migrate toward the surface in a reducing atmosphere. This film refracts light and disperses it into spectral colors, producing metallic and rainbow-like effects. In this study, silver nitrate (AgNO₃) was used to generate a luster effect on the glaze surface. During the reduction process, silver ions move toward the surface, creating a metallic sheen. Glaze formulations containing silver nitrate and various metal oxides—both lead-based and alkaline—were prepared and applied with a brush onto chamotte clay test tablets that had been biscuit fired at 1000 °C. The luster-coated samples were first fired to 1000 °C in a gas-fired raku kiln to ensure proper glaze maturation. When the kiln temperature dropped to 850 °C, the tablets were removed with tongs and immediately subjected to a reduction process. After reduction, gold, silver, and iridescent rainbow effects were observed on the test surfaces. However, the presence of fired chamotte particles in the clay body created a rough surface texture. Additionally, the high porosity of the chamotte clay caused partial absorption of the glaze, which reduced the metallic reflection and overall luster development. It was determined that applying a thicker glaze layer enhanced the luster effect. Despite the limitations caused by surface roughness, this texture also contributed an additional artistic quality to the final product, offering a distinctive aesthetic character that complements the luster appearance.

Özet

Lüster, sır yüzeyinde oluşan ince bir film tabakasıdır. Bu ince film tabakası, sırdaki metal iyonları indirgeyici bir ortamda yüzeye doğru hareket ettiğinde oluşur. Yüzeyde oluşan bu tabaka ışığı kırar ve ışığın spektral renklerine dağılmasını sağlar. Bu, yüzeyde gökkuşağı etkisi yaratarak metalik bir etki oluşturur. Bu çalışmada, sır yüzeyinde lüster oluşturmak için gümüş nitrat (AgNO3) tuzu kullanıldı. Gümüş iyonları indirgeme işlemi sırasında yüzeye doğru hareket ederek yüzeyde metalik bir etki yaratır. Gümüş nitrat ve çeşitli metal oksitler içeren, kurşun bazlı ve alkali sırlar hazırlanmış ve 1000 °C'de pişirilmiş bisküvi haldeki şamotlu çamur tabletler üzerine fırça ile uygulandı. Lüster sır uygulanmış numuneler, sır yüzeyinin gerekli olgunluğa ulaşması için ilk olarak gazla çalışan bir raku fırında 1000 °C'de pişirildi. Fırın 850 °C'ye soğuduğunda, test tabletleri maşa ile fırından çıkarıldı ve indirgeme işlemine tabi tutuldu. Test tabletleri indirgeme işleminden sonra analiz edildi. Test tabletlerinin yüzeyinde altın, gümüş ve gökkuşağı efektleri gözlemlendi. Ancak, şamotlu çamurdaki bisküvi parçaları (şamot) yüzeyin pürüzlü bir dokuya sahip olmasına neden oldu. Ayrıca, şamotlu çamur oldukça gözenekli olduğu için sırın bir kısmını emdi. Sonuç olarak, yüzeydeki metalik yansıma ve lüster oluşumu olumsuz etkilendi. Daha kalın bir sır tabakası uygulandığında lüster etkisinin arttığı gözlemlendi. Ek olarak, dokulu yüzey özelliği sayesinde, lüster etkisinin yanı sıra ürüne farklı bir sanatsal değer katıldı.
