Small 1/10" dia. wrinkles that I believe are caused by contaminate in the melt (or mould), I haven't found any particles but it apparently is a local freezing area. This is my suspected problem with eutectic alloys, not just Lino. They freeze in a very small temp band so there can be no 'migration' of air/junk.
