Primele sticl\u0103rii din Boemia au ap\u0103rut \u00een secolul al XIII-lea, \u00een p\u0103durile \u00eenc\u0103 virgine ale Mun\u0163ilor Metaliferi \u015fi din Lusace, \u00een masivul vestic al Gigan\u0163ilor \u015fi pe colinele de la Orlice. Sticl\u0103riile din p\u0103durile Boemiei devin importante \u00een secolul al XVII-lea, c\u00e2nd calitatea produselor a crescut considerabil prin aportul unor me\u015fteri veni\u0163i din Bavaria, Austria, Fran\u0163a \u015fi mai ales din Italia. Sticlarii din Boemia doreau s\u0103 imite sticla vene\u0163ian\u0103, dar topitura lor era prea dens\u0103 \u015fi avea un interval de plasticitate mai redus ca urmare a compozi\u0163iei solico\u2013potasice. \u00cen dorin\u0163a lor de ameliorare a calit\u0103\u0163ii sticlelor produse, sticlarii boemieni au descoperit, prin experiment\u0103ri numeroase, formula compozi\u0163iei silico\u2013potaso\u2013calcice, prin ad\u0103ugare de oxid de calciu. Prin aceast\u0103 re\u0163et\u0103 se ob\u0163inea cea mai dur\u0103 sticl\u0103 cunoscut\u0103 \u00een epoc\u0103, ceea ce permitea gravarea \u015fi t\u0103ierea ei \u00een profunzime, ca un cristal de roc\u0103. A fost un proces gradual, mutual \u015fi independent de perfec\u0163ionare a materialului. Cristalul de Boemia a devenit foarte c\u0103utat \u015fi a ini\u0163iat o adevarat\u0103 mod\u0103 \u00een toate centrele din Europa.
\nBautemps, pe care J. Barrelet \u00eel considera \u201eunul din cei mai remarcabili tehnicieni ai sticlei \u00een secolul al XIX-lea\u201d a transmis, intr-una din scrierile lui, compozi\u0163ia sticlei de Boemia, a\u015fa cum o aplicau sticlarii francezi care lucrau \u201e\u00e0 la fa\u00e7on de Boh\u00eame\u201d: nisip cuartos pisat \u015fi macinat \u2026 100 p\u0103r\u0163i, carbonat de potasiu \u2026 38 \u2013 42 p\u0103r\u0163i, var stins \u2026 18 p\u0103r\u0163i, nitrat de potasiu \u2026 1,25 p\u0103r\u0163i, arsenic \u2026 0,75 p\u0103r\u0163i.
\nDezvoltarea f\u0103r\u0103 precedent a sticl\u0103riei \u00een Boemia a fost posibil\u0103 datorit\u0103 capacit\u0103\u0163ii artistilor locali de a r\u0103spunde celor mai exigente cerin\u0163e \u00een leg\u0103tur\u0103 cu forma \u015fi decorul, subordon\u00e2nd propriile idei, inspira\u0163ia, creativitatea lor dorin\u0163elor clien\u0163ilor.
\nExperimentator de geniu, Friederich Egermann (1777 \u2013 1864) a \u00eembog\u0103\u0163it considerabil arta sticlei prin numeroase inven\u0163ii \u00een domeniul tehnologiilor \u015fi al tehnicilor de decorare. El a adaptat la sticl\u0103 arta pict\u0103rii cu email a por\u0163elanului, pe care o deprinsese la Meissen. I se datoreaz\u0103 introducerea pensulelor moi, din p\u0103r de cal, care au contribuit la ob\u0163inerea unor decoruri rafinate, \u201e\u00een stil Meissen\u201d. Printre inven\u0163iile lui Egermann se mai num\u0103r\u0103 glazura ro\u015fie, pentru care a acordat exlusivitate companiei \u201eVogelsang und M\u00fcler\u201d din Frankfurt pe Main, sticla lithyalin \u015fi hyalith (care imita malachitul, cornalina sau agatul), aplicarea unei pic\u0103turi de sticl\u0103 colorat\u0103 (\u00een general, galben\u0103) pe suprafa\u0163a unei piese incolore, lustruirea \u015fi gravarea ei \u015fi multe altele. Inven\u0163iile lui Egermann sunt folosite cu succes \u015fi ast\u0103zi. \u00cen 1842, lucrau \u00een atelierele sale 200 de sticlari, care decorau anual \u00eentre 136 \u015fi 170 de tone de sticl\u0103.
\nPiesa Egermann de\u0163inut\u0103 de Muzeul Na\u0163ional Pele\u015f, \u015fi anume \u201ecupa de logodn\u0103\u201d, are inscrip\u0163ie-dedica\u0163ie \u00een limba german\u0103, din cristal, pe

galben\u0103, care, dup\u0103 fuzionare cu sticla de baz\u0103 \u015fi lustruire, au fost gravate cu simboluri ale dragostei, p\u0103cii,
