The last photo, it seems that it has characteristics of ram's head, but not really defined, which makes you think of cac.
All in all I would say more cac than akro, but let's hear other opinions, also what size does it have?
Last photo- The third marble (from left) could be an MFC or cac slag, it would be advisable to know its dimensions
The sixth, also from the left, swirl Ravenswood for me, the rest akro slag
Ah, second from left I think it's swirl, not slag
Prego- Sì, le strisce tedesche trasparenti generalmente hanno una dimensione (ma ce ne sono comunque anche più piccole) intorno a 3/4 -19mm- un po' troppo per cac (although minimally there could be)
