xx-Sold Out-xx D01 The Science Behind the Magic of Acid Dyeing with Kimber Baldwin

Wednesday, April 29 from 9 a.m. to 4 p.m. at the Howard County Farm Heritage Museum – Blacksmith Shed

Acid dyes are magical when you understand what’s going on at a molecular level at each step in the dye process! Aqueous solutions, hydration spheres, reaction kinetics, thermodynamics, extinction coefficients, optics, color theory, isoelectric points, chromatography, molecular structure, thermal degradation, and the ultimate magic wand to control them all – pH. No science background required, and little math is involved. Each topic is discussed as relevant in the dye process. Students will leave class with a lab notebook of dye principles, skeins of beautiful yarn they’ve designed and dyed themselves, and an understanding of the science behind the dye process.

Skill level: Suitable for all. Maximum number of students: 12. Students should wear old clothes.

Class Code: D01 Class Fee: $110. Materials Fee: $75.

Kimber Baldwin is the owner of and “head chef” dyer at Fiber Optic Yarns. She has been fascinated by chemistry for as long as she has been obsessed with the fiber arts, learning to knit the same year she declared chemistry as her undergraduate major 35 years ago. She later obtained a PhD in chemistry from the University of Michigan and branched out in the fiber arts, learning spinning, weaving, and dyeing. In 2005 she decided to combine her love of science with her passion for the fiber arts and left a job as a research scientist to set up a dye studio in the furnace room of her basement. The first three years were spent optimizing the reaction conditions and exploring the limits of fiber-dye binding possibilities, the results of which are the intensely vibrant colorways for which Fiber Optic Yarns is well-known. The first skeins of yarn were sold through an Etsy store in 2008, followed by a website in 2011, and a brick & mortar store in 2014. Kimber will dye up anything that stands still long enough!

Since we weren't able to have a Breed Display Barn this year, some of you might be interested in this webinar that the American Sheep Industry Association recently sponsored.

"In this webinar we explore the amazing diversity of heritage sheep breeds found in America and how many are making a remarkable comeback as interest grows in small scale shepherding and in natural fiber arts. We discuss the decades long effort to bring rare sheep back from the brink of extinction and current efforts to develop new markets for their products. Learn about the conservation work and then listen to experiences of several rare breed sheep farmers as they recount the journey they have undertaken with their amazing sheep breeds"
