I use talc in ceramic glaze formulation. I have a 50lb bag of it in my studio.
It can make a nice matte glaze.
When I am using it, I use a respirator and gloves.Asbestos and airborne silica is a concern for sure. Here is some info about it, if you are interested.
My dad always used Corn Starch. My Gramps used a mixture of Corn Starch & Baking Soda. Not being a male, I never tried either of them. So, I say try BOTH & see which works best for you. I most definitely would NOT use the shaving lotion as suggested unless you’re a masochist!!!
One of my daughters is allergic to corn, and so for her, both cornstarch and talc is out. She’s using tapioca flour instead. I haven’t heard any complaints so far. I found it in the baking section of our grocery store.
I’ve tried using baking soda in my armpits before. Unless it’s dissolved in water, it changes the pH of my skin so much, I get pimples, and boy, do they hurt!
@snowberry Baking powder I used. Not baking soda. Also My pharmacist suggested Epson salts in my bath. I’ve been good all day with one wipe of a wet rag with baking powder.
@RedDeerGuy1 Since you don’t have ovaries & there’s NO evidence that talcum powder causes cancer in males, you should be safe to use baby powder if you choose to.
