Deep blue, fine particle, synthetic ultramarine pigment having rounded particles that are finer and more regular in size and shape than the natural ultramarine pigment. It is prepared by mixing anhydrous sodium sulfate or sodium carbonate with clay, silica, sulfur, rosin and charcoal then slowly heating in a reducing atmosphere. Variations in mixture proportions produce various shades of blue, green, violet and red pigments. The synthetic pigment is inexpensive and is used as an artist pigment in oil and watercolor, as a whitener in textiles and paper, and in wallpaper, soap, textile printing, and laundry bluing agents.一種深藍、具細微圓形粒子的合成群青藍顏料，其粒子的形狀及大小都比天然群青藍顏料的粒子更細微更規則。先以無水硫酸鈉或碳酸鈉混合黏土、矽石、硫、松脂和木炭，然後一邊減少氣體、一邊慢慢加熱而成。混合物的不同比例會產生不同濃淡的藍、綠、紫及紅色顏料。此合成顏料價格並不昂貴，能做為油畫及水彩畫的繪畫顏料，另可當作紡織、紙張、壁紙、肥皂及紡織印染的漂白劑，還可做為洗衣上藍劑。
