indefinite article before uncountable nouns

Hi, I think it is a common knowledge that some uncountable nouns can be changed to countable nouns (are susceptable to such transformations) if they are made into types. Does that mean if we could place the phrase "a type" and "a sort" before such a noun, then we would have a correct transformation of that noun? Could we have placed the phrase "a type" and "a sort" instead of making them countable?
