Pin Pricks And Bubbles

[swirlsrus]

What causes pin pricks? Are they a flaw?

Do bubbles increase or decrease the value of a marble? I also collect old bottles and bubbles are good

To much heat causes alot of the problems, bubbles inside are ok bubbles on the outside are considered "as mades" and depending on the specific buyer it will decrease the value if there is alot of pops, pinprick pops can be over looked but when they look like this they are oddities and its best to find a sling shot and have fun,, surface condition is what mib buyers look at to base their price range,,,bj

A "pin prick" is a chip.... just a nice word to describe a very tiny chip and not use the "C" word". A surfaced bubble - like a chip - decreases the marble's condition, and therefore value.

So how about roller marks, creases or foreign material in the matrix? I've got a couple Guineas and Slags that have foreign matter in the marble matrix, but it's small and some even under the surface. Beauty is, after all, in the eye of the beholder. If you were buying a mib with this condition, wouldn't you just consider it as adding character?

I wouldn't. I like mine smooth and shiny.

Almost all buyers will find cold rolls and imbedded debris as making the piece less desirable. Consequently it will negatively impact the value.
