Item details

Alum Mordant for Naturally Dyeing


Alum is a mordant for natural dyeing that creates bright, cheery, colourfast tones. Most natural dyes need to be used along with a mordant in order to help the colour attach to the fibre, and alum is the most commonly used.

Available in 50g or 100g recycled paper envelops.

Use alum at 8-15% of the dry weight of fibre (WOF). (Eg. For 100g of fibre, use 8-15g alum.)

In the samples in the last image, the bottom row was mordanted with alum, while the top row was mordanted with iron (another mordant used to darken colours). Each column is dyed with the same plant; from left to right, marigold, cochineal, and madder root.


Equipment and Saftey

Pre mix each dye vat ingredient in small containers of water to avoid lumps. Always add powder to liquid, not liquid to powder (to prevent powder from flying everywhere). Wear gloves and an apron to prevent staining your hands or clothes. Always dye in a well ventilated area and use separate pots and utensils from your cooking pots.

I am the only knitter behind Westlake, so please allow 5 days for me to knit, package and mail out your handmade goods. Thanks in advance for your patience!

In order to ensure that your Westlake piece reaches you safe and sound, each smaller hand knit item comes swathed in a bubble envelope. Larger orders will arrive in sturdy poly-mailers.

I package and ship items through Canada Post's regular air mail service, which means that, once mailed, your Westlake item should reach your door in:

- 2 to 9 business days (within Canada)
- 6 to 14 business days (within the USA)
- 6 to 21 business days (international)

PLEASE NOTE: Holiday shipping deadlines for regular air mail are as follows:
Within Canada Dec 11
US Dec 4
Worldwide Nov 27

This is the most economical shipping option, and so it unfortunately does not come with a tracking number or delivery guarantee. If your item hasn't arrived within the above timeline, please get in touch.

If you would like your package sent Express (comes with a tracking number and delivery guarantee), please get in touch and I would be happy to send you alternate shipping rates.

Please note that International and US parcels may be subject to customs fees at the border, depending on the country you're in, the value of the item and, well, luck (the process seems to be random). Unfortunately, this is out of my control, and I cannot be responsible for paying the fees. You can find out specific fees and duty free thresholds from your local postal service.

If you live in Toronto as well, feel free to contact me about pick-up options.
