Lastury p\u0159\u00edbuzn\u00e9ho st\u0159edomo\u0159sk\u00e9ho druhu Spondylus gaederopus slou\u017eily v neolitick\u00e9 Evrop\u011b k v\u00fdrob\u011b \u0161perk\u016f a ozdob, se kter\u00fdmi se obchodovalo na velk\u00e9 vzd\u00e1lenosti.

P\u00e9\u010de a manipulace<\/h3>\n

P\u0159esto\u017ee je schr\u00e1nka siln\u00e1, ostny a okraje misek se mohou p\u0159i n\u00e1razu odlomit. Lasturu proto zvedejte ob\u011bma rukama za t\u011blo schr\u00e1nky, nikoli za v\u00fdb\u011b\u017eky, a um\u00edst\u011bte ji na pevn\u00e9, stabiln\u00ed m\u00edsto. Prach snadno odstran\u00edte m\u011bkk\u00fdm \u0161t\u011btcem nebo proudem vzduchu. Pokud pot\u0159ebujete lasturu um\u00fdt, pou\u017eijte jen vla\u017enou vodu bez \u010distic\u00edch prost\u0159edk\u016f a nechte ji voln\u011b oschnout. Nepou\u017e\u00edvejte b\u011blidla ani kyseliny, kter\u00e9 by naru\u0161ily povrch a mohly by po\u0161kodit i barevn\u00e9 j\u00e1dro na vrcholu. Tuto barevnou skvrnu chra\u0148te tak\u00e9 p\u0159ed dlouhodob\u00fdm p\u0159\u00edm\u00fdm sluncem, aby si udr\u017eela svou sytost.<\/p>\n
