Millifiori, murrine, cane mosaic glass; this example generally referred to as, murrine. Canes cut and remelted together, then formed into this vase/pot. Probably not available today. From the Venice area, maker Salviati. One can see other examples - http://www.fratellitoso.it/collection3.htm.
The blurring light effect is not from anything in Photoshop. It's an artifact of the manufacturing process, and the way the light hit the vase. The surface is smooth (and unglazed). But the effect is one of depth.
This had just been posted when someone suggested it seemed soft. So it was easy enough to sharpen one step further. Keep in mind, jpg reduction can soften images and the blurring you see is intentional. It's literally how the glass looks.
Each cane, which you see head-on here, would have been created with multiple passes through multiple dies - which seems a lot of work and why if these were made, today, they might not even be affordable as these were, then. So the red core is red glass through a round die. It cools and is incorporated into some white-toned glass, which is fed into a star die. That cools. And then the cane is melted into blue and put through a larger round die. Cooled, into white glass, slightly larger round die. Cooler, into clear glass, star die. Cooled, into white glass, slightly larger star die. And so on. That would be my guess as to how the red-dot-center patterns were made. Someone correct me if they think that's wrong. And you can see the obvious distortion created when remelting the canes side by side and as ultimately made into this vase.
As I said, I don't know that these are still manufactured, nor any of a host of types of Italian 'murano' glassware that was popular in the 19th century, much of it based on rediscovery of 15th century Italian technique, much of that inspired by Roman glasswork over a millenia before that.
