Through consta™ study of changing needs, Baker ha? developed the widely used platinumrhodium alloy and applied it to such items as the reinforced rim crucible (prevents trapping of foreign matter under rim) and many other pieces in general use. Baker manufactures all forms and sizes of platinum ware for chemical and physical purposes, either of pure platinum or platinum-rhodium alloy. Old dishes, crucibles and apparatus of any form can be re-shaped, re-made or exchanged for new ware.

Nixon, who is a pioneer in the field, will give a series of evening lectures, open to the public, at Redlands on February 7, 15, 22, and 25. He will also give informal lectures, and will review the progress of x-ray microscopy research, including techniques developed at Cambridge to extend the resolution of the microscope down to 1 micron.
