I hope this is not going to be a big hoo haa - so my ink develop some musky smell and there seems to be slime. This is new to me because i've used fp for 20+ years and have inks I don't use kept in the drawer and they never develop slimes. I know what I am look at. The question is the slim caused by mold,bacterial or just that it is too concentrated. I have worked with surfactants and the slime really looks like it - just too concentrated. I thought of moldy inks as patches of slime rather than a more viscous liquid.
