Katazome\/ stencil resist print is a nice way to make pattern on indigo print fabric. As Indigo color fixes when it oxidizes, when there is something that prevents oxygen to touch the surface, this part does not get dyed and remain white (or the color of the base fabric). The Katanori paste is a rice flour based glue that you can apply on a fabric to prevent the air to touch the fabric surface so the part the glue is printed remain undyed.<\/p>\n\n\n\n

For middle Europe traditional Blaudruck, the print pattern is made with similar idea. Instead of stencil, the patterns are applied with the block print technique. The resist material is called papp, and it is often a secret recipe… although secret, one of the ingredients are copper sulfate which is toxic. So it is not very desirable to use, especially with fermentation vat. At Zeugf\u00e4rberei <\/a>in Austria, they make their own papp resist<\/a> with rice flour, rice bran and many more ingredients without toxic materials. As they use the iron sulfate indigo bath, the Zeugf\u00e4rberei papp is adjusted to fit their vat. <\/p>\n\n\n\n

Chinese katazome with indigo is called \u85cd\u5370\u82b1\u5e03 and they use calk with soy flour as resist paste. I tried this once with others at the Zeugf\u00e4rberei, and although it makes a very good stable resist paste that does not come off in the vat, it is also super difficult to remove it after dyeing. It has to be scraped off when dried after dyeing and washing.<\/p>\n\n\n\n

The Japanese traditional resist paste is made of sticky rice flour and rice bran, water and salt with some calk (for indigo vat use). I tried cooking this with Janina from Zeugf\u00e4rberei and we never really succeeded in getting a good paste. But now, I found few recipe on internet and on a book and I have it work now.<\/p>\n\n\n\n
