Katrina, This is a great outline! You and I are similar in that we have both started primarily with references and building on our information from there. I'm curious if you're going to go into any of the techniques that are currently being used for preventive conservation after the major restoration that took place in the last decade? I'm really interested to see the final product since I think you've chosen an incredibly interesting and controversial conservation piece. Eabrighi (talk) 20:23, 17 April 2016 (UTC)[reply]

Hi Katrina! What an intriguing case study to work on. I had no idea that so many restorators and conservators have worked on the Sistine Chapel, though I suppose it is not that surprising! It looks like you have a good start on your reference list. One thing that I would say is that it looks like most of your sources are news sources rather than scholarly sources. I would see if there are any scholarly case studies on these treatments to include in your reference list. I am really intrigued to find out more about the different types of restoration that have taken place on this work, and I really like that you have included a controversy page. With that many hands, it is bound that some of the restoration, especially the earlier restoration, may be doing more harm than good to the piece. It will be interesting to see how you go about describing the various treatments and materials and how they have changed and affected each other. Other than that I would recommend adding links to existing sites in Wikipedia, I know we are still early on in this and that may be in your radar. Very interesting! -Kendall — Preceding unsigned comment added by Ktrotter88 (talk • contribs) 22:18, 17 April 2016 (UTC)[reply]

Techniques and Materials Used - Magnesium???

It is impossible that Leonardo mixed "magnesium" into his primer, as metallic magnesium was first synthesized in the early 1800s - I checked the source Ross King (2012), but in the internet archive preview, I can not see the footnotes Ross King quoted. I believe it is a translation error: Instead of metallic magnesium, it should be magnesium carbonate (witch is simply dolomite or magnesia alba) or magnesium oxide, MgO, "burned magnesia"? Anyway, "magnesium" is definitely wrong.
