Soda Ash (Sodium carbonate) is used for scouring cotton and in the woad vat & woad extraction to increase alkalinity - SAVE £1.50p over the 50 gram price of Soda Ash.
The Soda Ash is weighed and packed in a polythene grip-seal bag. The bag is then labelled and put in a second grip seal bag for extra protection. I then place the packet in a small padded envelope and post it to you First Class.
