Spring water contains a great variety of salts. The combinations of these can significantly affect the dye results. Calcium and magnesium salts are responsible for the hardness of the water and have a negative influence on most natural dye processes since they reduce the quality of the dyes. With other dyes, these mineral salts are important Supplements that significantly improve the quality. The variations in the color achieved with madder, for example, depend not only on the age of the madder root used and the temperature of the dye bath, but also on the mineral content of the water. Hard water and a temperature of 70-80°C gives a more violet tone; if the dye bath is heated to boiling, a browner tone results. Thus the hardness of the water is responsible for the red tones in the carpets and flatweaves of the individual proveniences. Analysis of spring and well water in different areas gave the following results:
