Glass Powder Very Fine 0-50 µ, 100g

Glass Powder, also called Silica Powder, can be used as a filler or insulator for wood pores in musical instruments before actual varnishing.

You can also get a good  putty for cracks and small fissures and you can mix it with paint, deft or hot glue. This filler has suffered from the faults found in other fillers that usually appear light or dark depending on the orientation of the light. The presence of the glass allows useres to have a very homogeneous refractive index which normally does not show up when viewed with different angles of light.
