This PDF article has many different ways to dye yarn and roving. I read of a different method of jar dying that I will try tonight with some of my clean dry fiber. You wet the fiber in plan water, pack the jar tightly in layers: fiber-powder dye-fiber-powder dye-etc. I would use half of a 1/8th TSP of dye powder for each layer. The smallest I have is 1/8th TSP but I usually don't use nearly that much in jar dying. Remember: powders are concentrates of dye. Bring to just below boiling some vinigar water (at a ratio of 1/2 cup to one gallon...or a good dallop of vinegar).
Slowly add the hot vinegar water to the layered jar, tapping the jar to remove air pockets.
Now the next step it says to put the jar in a canning pot and bring to just below the boiling point and hold it there for an hour. I don't have a canning pot, so I will plan on putting it an oven safe pot filled with water and cooking it in the oven at 350 degrees for an hour.
And then there is anothe verison of cassarole dish dyeing.
>>CASSEROLE DYEING - Great for roving and yarns, any protein fiber.
1. Wet out roving or yarn, soak in vinegar solution. The arrangement of the fiber in the pan
determines color distribution. Can pinwheel, go back and forth either lengthwise or crosswise or
any other pattern you choose. Keep good records
2. Apply stock solution ( a 1 % solution works well) to fiber in planned pattern.
3. Add next layer of fiber and apply dye.
4. Add enough vinegar water down the side of container so there is about 1/2 inch water in bottom
of casserole. Cover tightly.
5. Place in preheated oven (180 degree F.) and heat for 20 minutes. If using silk be sure there is
enough water to keep it from scorching.
6. At end of 20 minutes add enough vinegar water down the side of the casserole to bring water
level with top of fiber. Gently push up and down to get water throughout the fiber. Cover tightly.
7. Return to oven and raise temperature to 200 degrees F. And hold for 1 hour.
8. Turn oven off and let casserole cool overnight.
9. Rinse, wash and rinse again until water is clear.<<
This version makes more sense to me than the last one I posted to my blog.
Result pictures are to follow soon.
