I was sold a blank as an s-glass but I believe it may be graphite . Every s-glass blank that I have stripped has been mostly white in color after the stripping . This blank I started to strip at the butt and it came out a dirty gray and when I put saliva on it it turned black . I have no idea what to think except that it may indeed be graphite . Opinions ? As always , TIA . Re: s-glass vs graphite

Carbon is charcoal grey. S-Glass is not. Sanding may reveal more - black residue is carbon. White residue is generally glass or kevlar.

Some S2 Glass Pre Peg can be purchased colored, I believe the cloth is dyed prior to the resins being added. If you "sand down" a blank like a Steffen Brothers brown colored or McFarland Black S2 Glass, it just dulls the color and will darken when wet. But many companies due use the off white colored S2 Glass and paint it.
You could still have a Carbon blank, the sanding residue will be similar like you rubbed your finger on a #2 Lead Pencil. Another thing, the fibers on a Carbon blank are much finer than Glass. Its also going to be a lot lighter by weight. Re: s-glass vs graphite

Thanks guys but I made a mistake when I posted this . It is not an s-glass like I thought , that's another blank I have waiting .
This is the way this blank is described ( Uni- direction fiber glass with carbon helix core ) and I believe the carbo helix core is why it is the color it is . Thanks again . Re: s-glass vs graphite

Sounds like one of the United Composites blank originally designed for the Aussie market. Sorry, only registered users may post in this forum.
