A comprehensive analytical study, which combined elemental and molecular analysis techniques, was performed to shed light on the chemical composition of these unique findings. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM EDX), inductively coupled-plasma mass spectrometry (ICP MS), flow injection analysis (FIA) with electrospray ionisation mass spectrometry (ESI MS), laser desorption ionisation mass spectrometry (LDI MS), and Raman spectroscopy were applied to reveal the elemental composition of the powders and identify the colouring agents in the pink and blue powders. The colouring agents in the pink powder were probably iron and the agent in the blue powder is Prussian blue. On top of that, it was also possible to determine the organic additives in these powders through pyrolysis gas chromatography with mass spectrometric detection (Py GC\/MS), atmospheric solids analysis probe ion mobility mass spectrometry (ASAP IM MS), and LDI MS. The organic constituents were identified as plant resin, beeswax, and fats. These results point to the preparation of faience\/pigment mixtures as oil paint.<\/jats:p>","DOI":"10.3390\/molecules27165205","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T20:58:08Z","timestamp":1660597088000},"page":"5205","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Secret Recipe Revealed: Chemical Evaluation of Raw Colouring Mixtures from Early 19th Century Moravia"],"prefix":"10.3390","volume":"27","author":[{"given":"Kl\u00e1ra","family":"Jago\u0161ov\u00e1","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Mon\u00edk","sequence":"additional","affiliation":[{"name":"Department of Geology, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1764-1173","authenticated-orcid":false,"given":"Jaroslav","family":"Kapusta","sequence":"additional","affiliation":[{"name":"Department of Geology, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Radka","family":"Pechancov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jana","family":"N\u00e1dvorn\u00edkov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pavel","family":"Fojt\u00edk","sequence":"additional","affiliation":[{"name":"Institute of Archaeological Heritage Brno, v.v.i.-workplace Prost\u011bjov, Tet\u00edn 8, 79601 Prost\u011bjov, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2533-5750","authenticated-orcid":false,"given":"Ond\u0159ej","family":"Kurka","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tereza","family":"Z\u00e1vodn\u00e1","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7070-6015","authenticated-orcid":false,"given":"Petr","family":"Bedn\u00e1\u0159","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8288-3999","authenticated-orcid":false,"given":"Luk\u00e1\u0161","family":"Richtera","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Mendel University in Brno, Zem\u011bd\u011blsk\u00e1 1, 61300 Brno, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3773-6439","authenticated-orcid":false,"given":"Luk\u00e1\u0161","family":"Ku\u010dera","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Science, Palack\u00fd University, 17. listopadu 12, 77900 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jas.2014.01.030","article-title":"Archaeometric characterization of 17th century tin-glazed Anabaptist (Hutterite) faience artefacts from North-East-Hungary","volume":"45","author":"Nagy","year":"2014","journal-title":"J.
