What you have to write down
Updated
Nothing here is prescribed by regulation, and all of it is what you would need if anybody ever asked.
Two record sets
Production records, one per batch, showing what was made and from what.
Test records, one per combination, showing the product was tested before it was sold.
The second is the one that matters most and the one least often kept, because a burn test feels like development rather than like evidence.
The pour log
Date and batch code. Wax product number and lot. Fragrance, supplier and lot, with the load as weighed. Dye and amount. Wick series, size and lot. Vessel supplier and part number.
Then the process figures: melt, addition and pour temperatures, and the cure start date.
Then units poured, units rejected, and where they went.
The batch code goes on the base of the candle, or the record cannot be connected to a product in somebody's hand.
The burn record
One per combination of the six variables, with the cycle-by-cycle observations and a verdict.
Dated, kept indefinitely, and cross-referenced from the pour log so a batch points at the test that approved it.
This is what you produce when a retailer, an insurer or a lawyer asks what you did to establish the candle was safe. There is no other answer.
The retrieval test
Hand yourself a candle with a code on the base. How long to produce the pour log, the lots of every material, the burn record for that combination, and the list of who received the batch?
Under an hour is a working system. Run it on a quiet afternoon rather than on the day it matters.
