Traditional indigo dye vat recipes include chemicals such as Thiox (oxygen reducer) & soda ash (alkaline base) & these work extremely well for standardised & effective indigo dyeing results. However, we are fully aware that many of us have a preference for a totally eco-friendly recipe & method for natural dyeing. We have therefore created an organic & eco-friendly indigo dye kit following the well established Organic indigo vat 1, 2, 3 method. This recipe combines our wonderful natural high quality indigo powder with Calcium hydroxide (the alkaline base) & a choice between natural antioxidants such as henna, or fructose powder - please choose which one you want when selecting the product. Follow the instructions provided with the dye kit. All ingredients can be composted, & also should be able to be disposed of in normal waste & drainage, though always check local requirements & regulations for waste disposal. This orgnic & eco-friendly indigo dye kit offers everything needed to get going with indigo Vat dyeing. The kit includes: 1 x 50g 100% Natural Indigo Dye 1 x 100g Calcium Hyrdoxide (also known as slaked lime) (alkaline base) 1 x 200g pack of Natural Henna, or Fructose powder (please choose which you prefer) 1 x pack of pH strips (x80 tear off strips) 1 x Instruction Booklet for indigo vat 1-2-3 dyeing. Please note, if you want a standardised & consistent dyeing result, & do not want to experiment using a natural antioxidant, then we recommend our kit which contains Soda Ash (as the alkaline base) & THIOX (which is the oxygen reducer), as this often yields more predictable results.
