A simple file designed for you to record test swatches of tannins used as mordants including source of tannin, weight of fibre used, iron modification and spaces for attaching swatches of your results. This has been designed to be used with the 2 step tannin/alum mordanting method for cellulose fibres, suitable for dyers who have knowledge of this mordanting process.
Please use for your own personal exploration of tannin mordants, commercial and found. You may not modify this document or on sell it, but you are free to use it as an example to devise a document that suits your own purposes.
