I-dye poly mordant
  • I've been looking all over for alum as a mordant for some natural dyeing. The only thing I could find was i-dye poly, which has a separate packet of "intensifier". I'm assuming it's a mordant, but could you tell me which it is? And can you use the "intensifier" to mordant yarn, drying it and leaving it to dye later (as you can with alum)? Thanks.
  • Alum and iDye Poly Intensifier are two very different chemicals and the intensifier is a carrier not a mordant. It helps to attract the dye to the fiber to create darker and brighter colors.

    If you are looking for alum, then please visit the webpage for alum: http://www.jacquardproducts.com/products/chemicals/alum.php and click the "where to buy" button. You can search for brick and mortar as well as online retailers.

  • Thanks for the info. I can't find any of your alum in Australia. Can't seem to find it at all! Everyone says you can find it at the supermarket, pharmacy or craft shop, but none I've tried have it.

    I wonder if it would work anyway... Maybe I'll try a tiny bit with my leaves and see what happens ;)
  • Don't use the iDye Poly Intensifier with natural dyes. It's a completely different kind of chemical and will not help your leaves.

    Other mail-order sources of alum in Australia include Kraftkolour and Batik Oetoro. Contact info is on my page, Sources for Dyeing Supplies Around the World (scroll down to the Australia section).

  • Hi Alrischa
    If you get really stuck finding Jacquard alum in Aussie then I have some here in NZ.
    Takes about four days to get there and the price to ship is fairly reasonable.
    cheers
