I read on Dick Sullivan's blog the other day about the use of Fumed Silica and gave it a try. I have posted a short essay on Facebook about this easy process.
I thought the results were worth sharing. I made the portfolio public so I think we can all see it even if we're not friended.
Feel free to comment.
Apologies to those who can't see the essay, here is a comparison of the difference.
