The electricity was cut off for the whole day because of some work on the lines. I spent the day not able to get stuck into the onyx. I found yesterday that it is not all that hard and I am able to work quite fast which is lovely. I am always impatient to uncover an idea once I have had it and the relative softness of the material helps in this. I polished a little piece today by hand and the colours begin to shine out. I shall have to be careful not to try to make the structure too fragile as i can tell that it does not have much integral strength. Tomorrow i will get going on it. i must check my mask as I could feel that I had inhaled some dust yesterday. Not good.
