Thank you, Ilia for your help. It was a great pleasure to speak again with you. I have not yet spoken to Ian, but hope to soon. It is a relief to speak with people struggling with the same technical issues, and solving the same problems. Presently, we have just the scratch coat in the dome, which looks good so far, and will be doing the rough coat (arriciato) in the coming weeks, as far as I know. It is difficult with hired plasterers, as they are very wary of fresco painting technique for plastering. They want to hose down every batch of mortar with huge amounts of water. You really have to keep an eye on things. I will keep you up to date with what happens, and post some pictures when we have some developments.

I am trying to send the "Mystery Green" to Mr. Kremer in Germany, who I heard will sometimes analyze colors.

Thanks again.
