I tried the contact email but never heard back. I hadn't done a lot more on fresco research because I had to prepare work for a show last weekend and knew that if I started thinking of fresco that would be the end of working towards the show. The show's over now and I'm ready to start. I'm still trying to track down the correct putty but found some that may be suitable. I'm assured it's very low in magnesium and that it will be suitable. I have spent the past few days downloading and reading everything on this site and have found a thousand answers and a million questions. I am so excited about starting. Guess it will be very different to watercolours and pastels though. When I start using the putty (which is in sealed bags) can I put what I haven't used into an airtight container and cover it with water? Could you tell me how to make fresco white? What would be a good colour selection to start with? Is it a good idea to make up colour tiles to begin with for reference? What are the special tools needed for applying the plaster? Why do you need to grind the pigments? I thought they would be fine enough to dissolve in the water. Sorry for all the very basic questions and the long message but enthusiasm has taken over common sense. It's very hard to get information in Australia. Bye for now and thanks again for the best site in existence.
