Achieving a Matte Finish
This is part two of a
multi-part tip on achieving a matte finish. Click here to go
to part one.
Although simply sandblasting and then firing a piece can achieve
a matte finish, there are several ways to improve the quality of the
final finish. One of these involves the use of manual sanding
after sandblasting in order to smooth out uneven spots and achieve a
better final finish. Here are some tips on this approach:
1. Try using a 400 mesh diamond hand pad. It
shouldn't be necessary to start out with a lower mesh (coarser) pad.
2. If you don't have a diamond hand pad, you can also
use wet/dry silicon carbide sandpaper. A combination of 400
mesh paper, followed by 600 mesh paper will work well.
3. If you're using sandpaper, place a sponge between the
paper and your hand for improved comfort and the improve the
evenness of the final finish.
4. An alternative to hand sanding is to use a electric
sander or grinder.
