Thank you everyone, I asked the question here again after reading the last question of this subject and the answers were over my head. I have no idea what RIO is or CMC gum solution or ferro frit are. most other chemica,l minerals, mysterious substances I am learning to recognize the names when I read them but am not really sure how to use or handle them. I only just figured out what flux is and that's how I know that gerstley borate is one. Currently I am only using commercial products and such knowing its better to wait and experiment with my own when I know A LOT more than I do now. My tiny bags of red iron oxide, gerstley borat and a couple mason stains are the first and only powdered ceramic items I have purchased so far, it took me 2 weeks to get up the nerve to even open the bag of Gerstley borate and a mason stain to mix up a test transfer tile. I've been looking at the bag of red iron oxide mystified by how to get it into liquid form safely. I have purchased a respirator for ceramics use and use it whenever I handle anything dry even wiping down my tables in case I cause clay dust to arise.
Again thank you for helping to educate me I read the forum posts old and new but it sometimes takes a awhile to actually figure out and understand what it is I am reading. Sometimes its rather like reading Greek street signs you know the sign in front of the train station says Train Station but you have no idea what the letters printed are. I know eventually ill figure it all out but the learning curve is massive at this point.
Sorry, Terry, I used the abbreviation RIO for Red Iron Oxide. While it is obviously good to error on the side of safety when handling clays and chemicals, some people take it to such an extreme that it is not only silly but a waste of studio time. Almost anything you inhale other than clean air is not good for you, but if you don't use gloves and a respirator to drive down a highway or ride a bike up a dirt trail or to watch your kid slide into home base or clean the cat box or sweep anywhere or put a kid in a sand box then you don't need gloves and a respirator to mix a little RIO (Red Iron Oxide) with water.
BTW, RIO is a main ingredient of ochres that our ancestors used to paint their bodies and cave walls and many people still used today to cover their entire bodies and is one of the many colors tossed into the air over crowds in India.

Kumkum (the red pigment thrown in the air during hindu religious festivals like holi or Krishna Janmastami) is made from mercury sulfide, not iron oxide.
