<div>Hi Fred,</div>
<div> </div>
<div>Excellent articles. I may actually give it a try. Definately not a way to save money though. Blanks seem to run about 70% of a good finished mirror so when you add all the materials and coatings - forget about the time and energy. Mirror making requires true dedication to the art of DO-It-Yourself.</div>

<div>As a long time Lapidary hobbiest I have several comments and questions. The only good way to store grits and polish, aside from being in seperate sealed rooms, is vertically - coursest on the bottom and polish on top. This minimizes possibility of contamination. Also, no fans in the room.</div>

<div>I am a little surprised at the preferance for Cerium Oxide as a polish. It is very aggressive and I reserve it for gems 8 or above hardness. Linde A would seem like a better choice at .3 micron size. Linde B might be a bit of overkill at .05 micron.</div>

<div>I never heard of Barnesite. Turns out it is a mineral associated with uranium ore and, as such, </div>
<div>is moderately radioactive - sort of like wearing 25 radium dial watches for twenty years.</div>
<div> </div>
<div>Any comment on the preformed blanks which seem to have become popular? </div>
<div> </div>
<div>Regards,</div>
