Identifikation af blyforbindelser og disses mørkning af hvide højlys på mestertegninger:: forekomst, produktion, handel, applikation og nedbrydning
Bibliographic record
Abstract
Misfarvning af blyhvide højlys på tegninger, fotografi og grafik er et almindeligt kendt fænomen i grafiske samlinger, når der er forurening i form af svovlbrinte til stede. Ændringen i det visuelle udtryk er til tider meget dramatisk, og værkernes kunstneriske værdi forringes derfor mærkbart. I flere tilfælde har man fx på Statens Museum for Kunst (SMK) valgt, at værkerne ikke længere er egnede til at udstille eller udlåne.<br/>SMK og Det Kgl. Bibliotek har i 2024 afsluttet et forskningsprojekt, der undersøger årsager til mørkning af højlys på kunstværker på papir. Projektet har kørt over de seneste 3 år, og har ført til en række spændende resultater. Det gør det nu muligt at give anbefalinger til, hvordan museer kan forsøge at sikre sig, at værker med blyhvidt undgår at blive misfarvede.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
