Answer
How do I write a specification for Giallo Siena marble?
The material fact sheet
Name the stone, name the source of the figures you are relying on, state the thickness, the finish, the edge and the application — and then say what is not covered. A specification for Giallo Siena marble is only as good as the batch reference it carries.
The figures
| Element | What to write | Source |
|---|---|---|
| The stone | Giallo Siena marble, and the names it travels under | Trade name list |
| The figures | The source you are relying on, and the conflict if there is one | Published technical sheet |
| Thickness | Nominal, with the calibration allowance | Edge and finishing practice |
| Finish | The surface and the edge profile, with the verdict | Finish dictionary |
| The batch | The batch the pieces are taken from | Our own stock statement |
| What is not covered | Which figures are published and which are ours | Our own operating practice |
Why this stone behaves this way
A stone specification fails at the point where the supplier and the buyer were talking about different numbers. Naming the source of every figure removes that failure, and it is the same discipline that makes a claim on this site checkable.
What these figures are, and what they are not A specification that names no source for its figures cannot be checked by anyone, including the person who wrote it.
