Sodium carbonate, also known as soda ash, is an effective industrial alkali. The manufacture of sodium carbonate from common salt was first developed in France in the 1790s and known as the Leblanc process. Muspratt was attracted towards manufacturing it, but could not raise the capital for the relatively expensive Leblanc plant and also considered that Dublin was not a suitable location for this. He perceived Merseyside as better because of the neighbouring coal fields, the proximity to the salt district of Cheshire, and the proximity to glassmaking industry. The glassmakers were the main prospective customer base for the sodium carbonate alkali.
