Blue Cold Process Soap Test 4

When I made the soap with the Blue Oil Soluble Color, I ran into a couple of surprises. First when the color was added the soap turned a blue color. Then it turned a murky grey then a bright pink. I nearly dropped the immersion blender! I poured the soap into the mold while it was still bright pink. As the soap cured it became grey again. Then it became purple in color! Come with me to the kitchen to achieve this gorgeous and shocking color.

    Taylor, truly enjoy your blog. Did you know these colors don’t “work” on your website? You can find them and click on them, then nothing. Thanks, Will

      I’m not quite sure where this problem is occurring for you, but let me see if I can help you with that. What do you see when you are clicking on the colors?

      If you click on the product code, that should bring up a small pop-up window that asks you for the quantity you want to have added to your shopping cart.
