Hey Dawn, welcome back. Do the things in the sagar work the same in pit fire and vs vsa???? Confused by the post here.
After the many pit firings we have done lately, the best colors come from salt, (rock salt), an sulfates and carbonates. Cobalt is heavy, should be used very carefully, and produces, of course, blue. We found it dangerous to the surfaces when used in combination with copper...creates a sort of raku glaze on the surface. Cow and horse dung, dried, produce great greens. Copper carb. will give you fantastic reds if you hit the right temp.....but be careful, too hot and it will melt on th surface producing a black and copper metal that will destroy nearly all surface while you try to get it off. Coffee is great especially when mixed with salt. Again, careful with the salt....too much and you will have crystals growing on your piece for years. salt soaked woods are great, burn with small wood, rather than logs, burn hot and fast. We have had the best results with this technique. Remember, every pit has different results...of the three pits we have fired in, all three have a consistant, individual personality. And, each firing is an individual....no easy predictable low/high fire rules apply, so go in with general expectations and you will always be pleased. Try lining the pit with bamboo leaves, or palms....creates great shadows in the cool spots. Fruit woods are best to get darker colors in the pit. River woods tend to give us lighter shades.
best of luck.......
