Ludwig's WRAP-UP
In summary, the phrase "lump of" is a common and grammatically correct way to describe an irregularly shaped mass or quantity of something. As Ludwig AI states, its usage is widespread. While it is versatile, it's more appropriate for neutral or informal contexts like news and general writing, less so for formal or scientific discourse. When you need to specify a compact mass of substance, phrases like "mass of" or "piece of" may serve as viable alternatives depending on desired precision. Just ensure that you're applying it to physical nouns and are consistent with its slightly informal tone.
