Watt attempted to commercialise his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775.

Technological advancements that were significant included;
• Development of microliths, that were very small stones which were mounted together on a shaft to form a serrated edge.
• Development of polished stones that was present in Mesolithic assemblages
The primary culture that was significant during the Mesolithic period was characterized by;
• Adaptation of hunter-gatherer lifestyle instead of group hunting.
• Development of sophisticated lithic tools and weapons which were typically smaller in size
• The use of pottery and textiles
• Use of simple ways to conduct burials
