BLEND-CB135 in an 88 mm tin, 40 hours
Ten sessions with a CD-10 wick at an 8 % load, the longest record on the site and the only one to use the dedicated soot and consumption procedure. It is the record that shows what a coconut-beeswax blend is actually for: an 8 % load that would weep out of a paraffin stays put.

A paraffin at 8 % would have shown an oil ring at the wall inside ten days. BLEND-CB135 showed none after the full record, which is the oil binding figure of 5.8 % doing its work: the coconut triglycerides hold what the beeswax esters would have pushed out.
The pool widened from 34 mm to 68 mm across the ten sessions and had still not reached the 88 mm wall at hour forty, which is why the record ran long. Soot at 4.8 is low for an 8 % load and the soot card collected only 3 mg over the final hour, against the 11 mg collected in the PARA-2281 record at a lower load.

Failure modes observed
| Trigger | Threshold | Known failure modes |
|---|---|---|
| BURN-SEP | hold temperature → above 75 C in the melter | Reheating the blend above 75 C between sessions scorches the coconut fraction and the burn smells of it. Reheat to 70 C at most. |
| BURN-SLUG | vessel size → tin over 90 mm | Above a 90 mm tin the pool stops reaching the wall and the outer 20 mm never melts. Use two smaller vessels rather than one large one. |
