diy grinding high quality telescope lens in slovenia

In the late 1970s I read that the optics maker Bernard Schmidt inventor of the Schmidt cameratelescope made a telescope lens using the glass from the bottom of a bottle when he was a boy Since I had plenty of grit and pitch leftover from making an 8 inch mirror I thought I would try my hand at making a lens in a such a way...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
