Re: [ATM] Grinding Ohara E6

Hi Dave,

>From all my reading up on E6 (I plan to start casting mirrors with shortly)
it is no different to working Pyrex or other borosilicate glass, i.e. it is
harder than plate glass and softer than fused silica.

Silicon Carbide for hogging, aluminium oxide for fine grinding and cerium
oxide or rouge to polish and figure.

Thomas.

Is there anything special about grinding E6?  Is it significantly different 
from working with Pyrex?
