Irish Glass,. 47 



of Londonderry it is stated that in the above year Joseph Moore 

 converted the sugar establishment in Londonderry into a glass- 

 house, and with his son, carried on the manufacture on a small 

 scale until 1825, when it was abandoned, owing to the imposition 

 of a heavy duty on glass. Probably only black bottles were made 

 in Londonderry. In the Custom House books, Londonderry is 

 entered as exporting glass to America in 1790 and some subse- 

 quent years, but whether it was manufactured there then is 

 uncertain. 



IRISH GLASS IN GENERAL. 



An Act of Parliament of 1746 placed a duty of 9s. 4d. on every 

 hundredweight of materials for crown, plate, flint and all white 

 glass, and 2s. 4d. on each hundredweight of materials for bottle 

 and green glass, made in Great Britain. Section XIX. of the Act 

 reads : — " Whereas the importation of glass into Ireland from 

 foreign parts, and the exportation of glass from Ireland may be 

 of great prejudice to the manufacture of glass in Great Britain, it 

 is enacted that from May ist, 1746, no glass of any kind, except 

 glass of Great Britain, be imported into Ireland." Section XXI. : 

 — "After May ist, 1746, no glass of any kind is to be exported 

 from Ireland under a penalty of ten shillings for every pound so 

 exported." 



From this it will be seen that at this period there was little 

 incentive to make glass in Ireland, and consequently few glass- 

 houses existed. The restriction on the exportation of glass from 

 Ireland imposed by the Act of 1746 was removed in 1780, and 

 shortly after that new glass-houses were erected in Cork, Waterford, 

 Belfast, Dublin, and Newry. 



No duty was placed on Irish glass until 1797, when every 

 quart bottle became liable to a duty of one farthing, and other 

 sizes in proportion. Dealers in glass had also to take out a licence 

 of twenty shillings. In 181 1 flint glass made in Ireland and ex- 

 ported became liable to duty, and in 1825 the final blow came 

 when a duty of ;^i2 los od. was placed on every i,ooo lbs. of 

 metal made in Great Britain and Ireland.
