Right this minute, my oven is pre heating to 400'F so that I can turn my baking soda into washing soda. Now, some of you may be wondering why one would want to do this, and just how does it relate to spinning? Well, washing soda is good for making laundry detergent, and general other cleaning things. But the very specific reason I want to do this is because in order to degum your silk cocoons, you need washing soda! And you need to degum your cocoons to make muwata (aka silk hankies) It's sometimes hard to come by, and I'm thinking it's a bit more expensive per ounce then baking soda. Don't quote me on that though. I haven't been on a big search for washing soda, and I have lots of baking soda kicking around. So this is the easier solution.
But wait! It's found it friday! Where did you find the recipe for this magical transformation??? I found this lovely post on Nature's Nurture, via a friend on Facebook. Sarah (of Natures Nurture) links to her original source as well on her blog post.
I'll give you the basic outline of the process you need to undergo to do this bit of chemistry/magic.
1. Pre heat your oven to 400'F
2. pour your baking soda on a cookie sheet. I lined mine with parchment paper so that removing it from the pan will be easier.
3. Bake your baking soda for 30 minutes, or until it looks grainy, more then powdery, isn't shiny anymore, and wont clump.
That's it. Simple! Now use in your silk cocoon degumming solution! And spin those muwata you just made with the help of chemistry/magic.
