Is handmade 25 weight paper thick enough for charcoal, watercolor, pastel, pencil, pen...etc art?

Where it might be fine for a charcoal drawing or sketch, pencil or pastel, it wont hold up under watercolor, it will swell up in the wet areas and when it dries, it will be catiwompas and you won't be able to press it flat.....Now, you might get away with using a paper of 65 lb Weight but not 25 lb.......By the way,....Poundages are calculated by stacks of paper of 500 count.....in other words, if that paper was stacked in a stack of 500 sheets, it would weigh in at 25 pounds so I think you might ought to check to see what the actual paper weighs in at cuz I'm betting it's heavier than 25 lb........Watercolor rag should always be at the very least 40 pound and hot pressed as opposed to cold pressed......cold pressed refers to a paper that has dried without the aid of heat.......hot press is usually a paper that is pressed by rolling it between hot rollers "per sheet" or is rolled on one roll or very long sheet.......that is then cut to size and put in stack and then banded together between plywood and left to cure.
