One difference between BRONZ/COPPRclay and silver clay, is that the base metal clay can really stain your nails and skin. Gloves in a Bottle is a great way of avoiding this. Apply a small amount before you start working, especially under your nails, and your skin will be as if covered by a invisible (and un-feelable) glove! Re-apply every four hours. Gloves in a Bottle is also fantastic if you suffer from dry sensitive skin, eczema, dermatitis, or psoriasis. It acts as a shielding lotion, so keeps "bad things" out, and good things (like moisture) in - perfect when gardening. It is unscented, non-greasy, non-sticky, and super-light so you wont feel it on your skin.
