Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“The specification states, that “ The manner of using the salts, or alcalies, obtained from the spent ley of soap makers, in the manufacture of window glass, and common glass hollow ware, as bottles, vials, &c. is to combine it with silex and caustic lime; when what is called flint glass is to be made, the oxides of lead, and (excepting alcalies,) the other materials usually employed in the manufacturing of that article, are to be added." The mode of procedure, generally, being the same as that heretofore practised. The quantities used must be determined by experience, or by testing, by proper reagents, the composition of the particular mass of salts, or alcalies about to be employed.”
