Natural Dye - Tannin

Wingham Wool Work

£10.4

Tannic Acid is a plant-based mordant widely used in natural dyeing to improve colour adhesion on cellulose fibres such as cotton, linen and hemp. Traditionally derived from materials such as oak galls, oak bark and leaves, tannic acid provides the tannins needed to help natural dyes bond more effectively to plant fibres. In natural dye processes it is often used alongside mordants such as alum or aluminium acetate. The tannin treatment prepares the fibre so that the mordant and dye can attach more strongly, resulting in deeper colour, improved fastness and more even results. This high-quality

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as WINGHAM WOOL WORK LIMITED, number 09928953. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
