MB Stone’s identification kit starts with a useful question: what is the stone?
MB Stone’s kit combines identification aids and written guidance developed with geologist Karin Kirk.

MB Stone Professional’s Stone ID Kit brings together identification aids, a flow chart and an instruction booklet. The company says it developed the kit with geologist Karin Kirk and uses it in educational settings, including its introductory restoration training.
That emphasis is useful for a shop because a trade name does not always answer every question about a material. Before choosing a treatment or attempting restoration, the person doing the work needs an appropriate basis for identifying the surface and understanding what further information is required.
Keep observations with the job
When a material question arises, preserve the supplier information, photographs and any documented observations in the job file. Distinguish a confirmed identification from a preliminary impression. If uncertainty remains, seek qualified assistance before selecting a process that could alter the surface.
The kit contains items requiring careful handling, including acid and blades. Its instructions and applicable safety information belong with the kit; this article is not a testing procedure.
For a fabrication or restoration business, the larger lesson is to make identification part of the workflow rather than an assumption. A structured reference tool can support training and better questions, while the decision about a particular stone should rest on appropriate evidence and expertise.
