Slow made is the basic requisite for natural ecological colours of quality.
Almost always textiles need at least one premordanting bath for proper fixing with natural dyes. This requires plenty of time; rapid processing results in colours that are less fast. Tinctoria uses the environmently friendly alum. This substance consists of plant remains bonded with aluminium salt. The crust of the earth contains 15 % alum.
For screenprinting or painting Tinctoria uses printing pastes, containing plantextracts and aluminium acetate. This fixing salt is non-toxic for the environment.
Everything is produced in small editions. Max length of printing is 6 m.
