Which of these chemicals could cause a mixture of rust, age spots look for a piece of stoneware?

It will also be High Fired after the stain sets, so the mixture should not explode, disappear at high temperatures. alumina hydrate, barium carbonate Bone Ash Shadow Borax roasted green chromium oxide cobalt carbonate cobalt oxide copper oxide copper carbonate, copper sulfate Cornwallstone CMC Custer Feldspar Dolomite Black Feldspar – Minspar – Kona F4 – G200 Fluorite Gerstley Punch Laguna borate borate solution Mulcoa 20 Illmenite rubber, chromate of iron oxide Black iron oxide granular red iron oxide yellow iron lithium carbonate magnesium carbonate manganese carbonate manganese dioxide Rutile silica Syenite Nickel Silver Soda Ash Sodium nitrate Spodumene Strontium Carbonate silicate powder tin oxide titanium dioxide Ultrox Vermiculite Volcanic Ash Whiting Wollastonite, Zircopax oxide yellow ocher zinc

probably want an oxide of a glaze will not stain. Rust is basically iron oxide red. The problem with red iron oxide is that it does not fire too well what you may want to mix some Gerstley borate (a glass above) to promote adherence. But if taken in excess will be brilliant. Not sure of how resistant it is to high heat, however, I could record black. If you really need black as black copper oxide, has a black graphite-like look. If using copper oxide and paint it black and take it immediately with a sponge oxide will remain in the pits and fissures giving the piece and antique look and emphasizing dimensionality three. manganese oxide can also be used for this is more brown than black. If in doubt you can always use acrylic washes after shooting paint over the desired color effect. Just do not use solid colors, then you could have used any material. Delgado lava continue to show that is made of clay.
