A better etching solution
posted March 5 2011 21:50.39 by Giorgos Lazaridis

I've heard about this etching chemical in the past, and i plan to test it one day. The problem is that it needs a preparation that is not as straight-forward as with ferric chloride. On the other side, it has many advantages, with most important the fact that this solution can be reused like a million times, unlike other chemicals that have limited lifespan - so we can label it as "green"! Read this post to find out how to make it, and if you do test it, send me the results.
