Fusinite Simulator Landing
What is your sample, before the lab confirms it?
Type your feedstock and production temperature, add whatever analysis you already hold, and the Fusinite Simulator resolves the rest with our locked empirical rules. Every number comes back with its provenance attached — provided, exact, converted or modelled — and anything that cannot be honestly derived is left visibly unresolved rather than quietly invented.

Resolve a partly characterised sample
Analysis takes time and money. Most decisions are made before the certificate arrives — on a feedstock, a kiln temperature and a single carbon number. The Simulator turns that into a defensible working picture, and tells you plainly where the picture ends.
Provenance on every value
Provided, exact, converted or modelled — labelled per field, never averaged into one vague confidence score. A green check means provided, not verified correct. QC is a separate badge.
Your evidence always wins
Provided beats modelled, exact beats converted, and a calculated value never overwrites the measurement it came from. Your reported ratios are kept as evidence even when an exact route exists.
Report reading you approve
Upload what you have. We match values to our database and show each one with exactly where it came from. Nothing from a file enters a calculation until you confirm it.
Locked empirical rules
Rule 1 converts H/C and H/Corg. Rule 2 links measured mean Ro and direct ratios. Rule 3 runs the raw Ro>2 → Freact → Finert → Cinert exact chain.
Forbidden cascades blocked
A modelled ratio cannot be re-laundered into reflectance, inertinite or a fabricated carbon mass. Provenance cannot be washed clean through an algebraic identity.
A route to certainty
Where evidence is missing, the Simulator names the Fusinite Lab analysis that would convert a planning estimate into a measurement.
Four labels, no ambiguity
The Simulator is evidence-aware by design. It will estimate a missing field, but it never lets a planning estimate pass as a laboratory measurement.
Provided
Typed by you or approved from a report. Carries your own QC status and is never overwritten.
Exact
Calculated directly from compatible confirmed measurements. Inherits the QC and uncertainty of its inputs.
Converted
A validated Fusinite conversion, applied only where the field is genuinely missing.
Modelled
A 90% interval, model domain, model version, dependency trail and a qualitative confidence label.
From four inputs to a resolved sample
Register and type
A sample ID is issued, then you type feedstock, actual production temperature and one carbon anchor.
Upload and confirm
Optional reports are read and matched. You confirm each located value and its source.
Simulate and publish
The engine resolves what it can, labels every field, and hands the sample to Lens and Optimiser.
The estimate, with its limits attached
When nothing direct resolves the ratios and your actual production temperature sits between 500 and 850 °C, the approved fallback applies. H/Corg then follows through locked Rule 1.
Validated on 201 unique records across 21 projects under strict leave-one-project-out validation. Routing temperature through mean Ro was tested, did not improve project-balanced H/C prediction, and is prohibited.
Where the Simulator stops — deliberately
Never modelled from temperature alone: mean Ro, reflectance standard deviation, raw Ro>2 fraction, Freact, Finert and Cinert.
Never inferred at all: a carbon mass with no provided total C or Corg anchor. Without that anchor the run is blocked rather than guessed.
Yield is not produced here. It belongs to Fusinite Optimiser after handoff. Where reflectance or inertinite outputs are required, the Simulator points you to the relevant Fusinite Lab analysis.
