Mordant - Soda Ash

Wingham Wool Work

£5

Soda Ash (sodium carbonate) is an essential dyeing auxiliary used to fix reactive dyes to fibre, it creates the alkaline conditions needed for the dye to bond permanently with the fibre. When added to the dye bath, soda ash raises the pH, allowing reactive dyes to chemically attach to cellulose fibres such as cotton, linen and rayon. Without it, colour fixation will be significantly reduced, resulting in weaker shades and poor wash fastness. This high-quality soda ash provides consistent and reliable results, making it a staple for both professional dye studios and home dyers. It is typically

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.
