The Alchemy of Indigo
The smell wafts up from the handwoven, indigo-dyed cotton cloth as I’m ironing it. It’s an unmistakable odor—a little sweet, a little pungent. If you’ve dyed with indigo, you know this smell and you understand the magical, transformative process of this dye.
Many people have been taken in by indigo’s magic. You don’t have to be a dyer to experience it. I witnessed it last year, sitting in a packed Santa Fe theater for the release of Mary Lance’s captivating documentary, “Blue Alchemy: Stories of Indigo”. This film weaves together stories of indigo’s cultural traditions and people who are reviving it. The collective “ohs and ahs” from the viewers confirmed indigo’s magical powers taking hold.

Here’s a simplified version of the dye process: Once the dyebath is prepared, it’s a deep, rich blue with scum on top.
After dipping the cloth into the bath and removing it, the cloth is a pale teal green. But once the air starts to oxygenate the cloth, it turns blue.
The more dips into the bath, the darker the cloth becomes.
So are you now intrigued to try it yourself?
And if you’re on the east coast next Friday, Sept.14, you can join botanist, chemist, and world-recognized natural dye expert Michel Garcia for an inspiring guided tour through Winterthur’s museum and grounds in Delaware (www.winterthur.org). He’ll also be conducting a workshop “Provençal Prints & Organic Indigo on Cotton” Sept. 11-13.
