How to Make and Use Precipitated Calcium Carbonate Silver Polish
Source: This video was created by the Canadian Conservation Institute and is included in CCI Note 9/11 How to Make and Use a Precipitated Calcium Carbonate Silver Polish.
This video and the cited Note discuss how to prepare and use silver polish made with precipitated calcium carbonate. This polish is considered mild because it does not remove too much of the silver under the tarnish. Using this silver polish avoids using commercial polishes, which may contain unknown abrasives or additives that are harmful to the object.
