Dear All,

Just wanted to add a quick note that in reading a Robin Hopper book last night I found a sentence or two where he talked about using bone marrow on pots to be bisqued. It created a dark hue that seems to come through. Just wanted to add this for the person inquiring about organic materials used to create different textures or images on pots about to be bisqued. I haven't done this so have no idea of the outcome but did want to add this to the forum in case anyone was interested.

Nelly;
I am thinking that this bone marrow would really stink if you fired it on your work. When you mix up a glaze with bone ash, and you get it wet as you add water, it gives off a gas. If you try this people, use a vented kiln. Does Robin Hopper say anything about odors?

Dear TJR,

No Robin did not mention anything about smell. He did include a picture of how it was used. If you want I can provide you with the exact page number reference. It is in one of his books that I just purchased last Christmas. "Ceramic Spectrum" I think. He does provide an image that shows the hue created by the end of the beef bone. I had never heard of this before so it did become rather interesting for me. I will not be trying it myself but did think it was worthy of putting it up for others to know that this is one other "organic" substance they may want to try.

Nelly;
I know bone ash is calcium phosphate, and it stinks when it hits water. I think they have a synthetic version, but I'm still using the old stuff. I think I have a copy of Ceramic Spectrum somewhere, so will look it up.

Okay, if you want to use an organic substance to produce a dark hue use honey, do it after the bisque, and fire it at ^022.




Good luck!
