I am thinking about using sections of tile for a base for a mold.
Attributes that I would like, importance in descending order (most important first):
- Flat, like glass, with very little variation
- Smooth, like glass
- 12" x 12"
- Relatively inexpensive
- Relatively durable
It doesn't have to be tile, that's just where I was thinking of starting.
Anyone have ideas on what might "fit the bill"?
