ABSTRACT:
Apparatus for removing a fused silica glass object from a rotating pot has a gripping member which grips the upper rim of the fused silica glass object and a rotational synchronization member connected to the gripping member which is lowered vertically into frictional contact with the rotating pot. The rotation of the pot drives the rotation of the synchronization member which drives the rotation of the gripping member. The object can be withdrawn vertically from the pot without the angular velocities of the object and pot diverging.
