The bowl should have a thicker rim to it, that bowl wouldn't be able to resist heat. Also, the normals are rather iffy, you're getting some really hard edges there. Make the bowl thicker overall, bevel the top edge, and adjust your normals, then you'll be on your way. Also, if you aren't willing to accept constructive criticism, then A) you shouldn't bother posting your work and B) you're only hindering ability to become a more skilled artist.
If you still need a look at a barrel texture, heres one I did...only its made of wood...
In Maya 3D Viewport (ie. not rendered)
UV Map
The Wood texture I used as a base (of course, highly modified in photoshop...
Good luck, continue posting your work and open up to criticism, you'd be amazed the benefits you get from listening to others opinions and trying them out on your work.
