Coloring Agents
* Copper:
* Copper(I) oxide (Cu2O): Red
* Copper(II) oxide (CuO): Green to blue
* Copper carbonate: Greenish-blue
* Copper sulfate: Blue
* Iron:
* Iron(II) oxide (FeO): Green
* Iron(III) oxide (Fe2O3): Yellow to brown (rust)
* Iron(II) sulfate: Yellowish-green
* Cobalt:
* Cobalt(II) oxide (CoO): Blue
* Manganese:
* Manganese dioxide (MnO2): Violet
* Manganese sulfate: Pink
* Chromium:
* Chromium(III) oxide (Cr2O3): Green
* Nickel:
* Nickel(II) oxide (NiO): Yellow to green
* Tin:
* Tin(II) oxide (SnO): Yellow
* Tin(IV) oxide (SnO2): Opacifier
* Gold:
* Gold chloride: Ruby red (colloidal gold)
Other Factors Affecting Color:
* Oxidation state of the metal: The oxidation state of the metal ion greatly influences the color produced.
* Presence of other elements: The presence of other elements in the glass or enamel can alter the color produced by a given metal ion.
* Temperature: The temperature at which the glass or enamel is fired can also affect the final color.
Note:
* The colors produced by these salts can vary depending on the specific composition of the glass or enamel, as well as the firing process.
* It's important to use caution when handling these salts, as some can be toxic.
This is just a starting point. There are many other salts and oxides that can be used to color glass and enamels, and the specific colors produced can be quite complex.
