Name the requested glue
State whether the inquiry concerns gelatin, hide glue or bone glue. Include the reference product you currently use if available, and explain which parts of that reference you want the supplier to compare.
Document the process requirements
Provide your own required test method and acceptance criteria. Ask for the proposed product's technical documents and the meaning of any grade designation before using that designation in a purchasing specification.
Review the supplied documents
Ask for handling, storage and packing information for the specific proposal. Give your reviewer the original document set and identify any points that need clarification before arranging a sample.
Clarify the glue description
If a quotation uses a grade code, ask for the test method and product description associated with that code. Give your technical reviewer the proposed documents together with your process requirements. Ask for clarification of any missing handling or storage information, and identify the exact glue proposal to which a sample or document belongs.
Distinguish the requested glue family in your enquiry, including whether your brief concerns industrial gelatin or bone glue. Ask the supplier to explain the proposed grade description and the test information accompanying it. Describe the intended evaluation method in your own purchasing brief, and request clarification wherever a grade label cannot be compared directly with your acceptance requirements.
