Interpretation:
The reason should be explained that why the daguerreotype cases were not made from horn or horn powder.
Concept introduction:
The horn is a non uniform natural plastic material obtained from the livings. It had a wide application in Europe and England for the formation of daily use materials like spoons, lantern windows, combs, buttons and many decorative items. However, in recent days the manufacturing of horn products are least found.
This material is not the same as synthetic plastic but it is much relevant to the plastic as its importance and uses has raised the necessity of substitute plastic materials.
Daguerreotype is a type of photographic process used in years 1840-50. The surface of the daguerreotype cases are created mirror like and they are found to be fragile.
