Answer
Can Giallo Siena marble take a flamed finish?
Every finish, with an honest verdict
No. Flaming is a granite process: heat expands the surface crystals until they fracture. Giallo Siena marble does not take it, and a flamed Giallo Siena offered on the market is a different material wearing the name.
The figures
| Finish | Verdict | Source |
|---|---|---|
| Flamed | No — not a finish for this stone | Finish dictionary |
| Sandblasted | Ask — possible, depends on the piece | Finish dictionary |
| Honed | Yes — standard order | Finish dictionary |
Why this stone behaves this way
Flaming works by fracturing a crystalline interlock that a granite has and a marble does not. Giallo Siena marble is calcitic and its surface is cut, not fractured, so the process has nothing to work with.
What these figures are, and what they are not This is a statement about the lithotype, not about one supplier. Any supplier offering a flamed Giallo Siena is offering something other than Giallo Siena marble.
