Historie pou\u017e\u00edv\u00e1n\u00ed p\u00edskovce ze Szyd\u0142owce je kr\u00e1sn\u011b patrn\u00e1 nap\u0159\u00edklad v architektu\u0159e Var\u0161avy, kde z tohoto kamene bylo postaveno mnoho budov a v pov\u00e1le\u010dn\u00e9m obdob\u00ed jich bylo mnoho rekonstruov\u00e1no a zrenovov\u00e1no.<\/p>\n

Sou\u010d\u00e1st\u00ed zm\u00edn\u011bn\u00e9 historie je nap\u0159. tak\u00e9 lom Szyd\u0142\u00f3wek – Saspol, v n\u011bm\u017e byla t\u011b\u017eba zah\u00e1jena v roce 2016. K\u00e1men z tohoto lomu je typick\u00fdm prototypem szyd\u0142oweck\u00e9ho p\u00edskovce. V z\u00e1vislosti na hloubce t\u011b\u017eby lze z\u00edskat p\u00edskovec b\u00edl\u00e9 a b\u00e9\u017eov\u00e9 barvy. Ob\u011b maj\u00ed stejn\u00e9 fyzik\u00e1ln\u00ed a mechanick\u00e9 parametry. Vyzna\u010duj\u00ed se jemn\u00fdmi, \u010di dokonce velmi jemn\u00fdmi zrny s k\u0159emi\u010dit\u00fdm pojivem.<\/p>\n

Stoj\u00ed za zm\u00ednku, \u017ee je mo\u017en\u00e9 si k\u00e1men vybrat tak, aby byl 100% \u010dist\u011b b\u00edl\u00fd. Na druhou stranu je obt\u00ed\u017en\u00e9 vybrat dokonale b\u00e9\u017eov\u00fd materi\u00e1l – b\u00e9\u017eov\u00e1 barva je toti\u017e u szyd\u0142oweck\u00e9ho p\u00edskovce v z\u00e1sad\u011b sp\u00ed\u0161e p\u0159ibarven\u00edm.<\/p>\n

Ve velk\u00e9m objemu tak bude obt\u00ed\u017en\u00e9 doc\u00edlit jednolitosti b\u00e9\u017eov\u00e9 barvy.

P\u00edskovec Szyd\u0142owiec je vhodn\u00fd pro vn\u011bj\u0161\u00ed pou\u017eit\u00ed.

Impregnace nen\u00ed nezbytn\u00e1, ale doporu\u010duje se.

P\u00edskovec Szyd\u0142owiec m\u00e1 velmi dob\u0159e hod\u00ed k mechanick\u00e9mu opracov\u00e1n\u00ed. S ohledem na svou tvrdost je ov\u0161em pot\u0159eba k opracov\u00e1n\u00ed zvolit vhodn\u00e9 n\u00e1stroje. K \u0159ez\u00e1n\u00ed lze ur\u010dit\u011b pou\u017e\u00edt b\u011b\u017en\u00e9 n\u00e1stroje, av\u0161ak je pot\u0159eba po\u010d\u00edtat s jejich n\u00edzkou \u017eivotnost. P\u00edskovec Szyd\u0142owiec se vyzna\u010duje vysokou abrazivitou, tj. velk\u00fdm abrazivn\u00edm opot\u0159eben\u00edm n\u00e1stroj\u016f. D\u00edky tomu je nap\u0159. vhodn\u00fd k brou\u0161en\u00ed diamantov\u00fdch n\u00e1stroj\u016f.<\/p>\n

Szyd\u0142owieck\u00fd p\u00edskovec  se vyr\u00e1b\u00ed v r\u016fzn\u00fdch povrchov\u00fdch \u00faprav\u00e1ch. Standardn\u011b se dod\u00e1v\u00e1 s brou\u0161en\u00fdm, \u0161t\u011brkov\u00fdm, \u0161t\u00edpan\u00fdm a \u0161pi\u010dat\u00fdm povrchem.

Vzhledem ke sv\u00e9 struktu\u0159e se nedoporu\u010duje pro vodorovn\u00e9 obklady v interi\u00e9ru. Tam m\u016f\u017ee p\u016fsobit probl\u00e9my s udr\u017eov\u00e1n\u00edm \u010distoty a navzdory impregnaci povrchu neodol\u00e1 skvrn\u00e1m od v\u00edna nebo k\u00e1vy.<\/p>\n

Skv\u011ble naopak vypad\u00e1 na dekorativn\u00edch st\u011bn\u00e1ch – v le\u0161t\u011bn\u00e9 nebo \u0161t\u00edpan\u00e9 struktu\u0159e. Jednou z nejzaj\u00edmav\u011bj\u0161\u00edch realizac\u00ed je v\u00fdroba \u0161atn\u00ed sk\u0159\u00edn\u011b – v\u010detn\u011b \u010del – na zak\u00e1zku jednoho z architekt\u016f.<\/p>\n
