Grinding Wheel: Silicate-Bonded (Machinery's Handbook, 1924)

A wheel bonded with silicate of soda and baked at a much lower heat than a vitrified wheel; quick to make, can be very large (up to 60 in), and wears little while cutting cool. Source: Machinery's Handbook (1924), pp. 1101-1102. Unknown: proportions and temperatures. Picture: the handbook's text.
