i am not sure where this sould go so please move it if it in the wrong place.
i was down at a large printing place to use their densitometerand the owner took me down to their old darkromm and asked if any of the left over materials had any value. i haven't takena inventory but wanted to ask if any of the folling item can be of any use to anyone here, kodak alum plates ton's of several dif sizes of them . i belive are printing plates, very thin photoplates ? could they be used for alt process, i read from time to time people use alum to print on? also many different types and colors of material kind like ruby lith. i got the impression that they just want to get rid of it all not just sell it . tho i do belive it has value as scrap metal.
what could this stuff be use for.
