To confuse the issue, the term "component" is rarely encountered.
I have a somewhat related question. In the olden days there was a company named "Schott". They supplied a wide variety of glass, for lenses and, I think, for labware and glass tubing.
Now I notice that the glass top of the stove that came with this house says "Schott- Ceran".
Same company?
