Pit Salt Glaze Testing

As part of my high school, I may have the opportunity to try salt glazing.Therefore, I have done some thinking about how to develop colors and efffects in salt glazes. So, anyone who is currently salt glazing , please give me some input on my ideas.

First, I thought of mixing lead oxide powder with the salt in my pit . Also possibly feeding a gas like mercury hydride into the pit, or covering the pots in mercury prior to firing. Also putting a wash of selenium and cadmium over the pot. Possibly by trying a chemical raku by taking out the red hotsalt glazed piece and dipping it in a solution of copper, sulfuric acid, and water.

Though these ideas are very hazardous in nature, they are only ideas and are out for comment only and not as ideas to try, therefore I take no responsobility for any injury or death as a result of someone actualy trying them. As this behavior poses severe health risks.
Thanks and Happy Glazing!
