Natural varnish may have protected 37,000-year-old Chauvet Cave art, UV scans show

قدرتی وارنش نے 37 ہزار سال پرانی شووے غار کی مصوری کو محفوظ رکھا ہوگا، یو وی اسکین سے انکشاف

प्राकृतिक वार्निश ने 37,000 साल पुरानी शोवेट गुफा की कला को सुरक्षित रखा होगा, यूवी स्कैन से खुलासा

Natural varnish may have protected 37,000-year-old Chauvet Cave art, UV scans show

Key points

اہم نکات

मुख्य बातें

  • Researchers using ultraviolet light scans have found that a thin natural layer of calcite may have acted as a varnish protecting the 37,000-year-old paintings in France's Chauvet Cave.
  • The team worked from about 2.5 metres away to avoid damaging the fragile site, and found the mineral coating glowing blue under UV light over parts of the artwork, including the famous Horses panel.
  • The findings, published in the journal ACS Omega, also suggest some drawings were made with heated charcoal, after orange glows were found near torch marks.
  • الٹرا وائلٹ روشنی کے اسکین استعمال کرنے والے محققین نے پایا ہے کہ کیلسائٹ کی ایک باریک قدرتی تہہ نے فرانس کی شووے غار میں 37 ہزار سال پرانی مصوری کو وارنش کی طرح محفوظ رکھا ہوگا۔ ٹیم نے نازک مقام کو نقصان سے بچانے کے لیے تقریباً ڈھائی میٹر دور سے کام کیا، اور مشہور ہارسز پینل سمیت مصوری کے کچھ حصوں پر معدنی تہہ کو یو وی روشنی میں نیلا چمکتا پایا۔ جریدے اے سی ایس اومیگا میں شائع شدہ نتائج سے یہ بھی پتہ چلتا ہے کہ کچھ تصویریں گرم چارکول سے بنائی گئی تھیں، کیونکہ مشعل کے نشانات کے قریب نارنجی چمک ملی۔
  • अल्ट्रावॉयलेट रोशनी के स्कैन का इस्तेमाल करने वाले शोधकर्ताओं ने पाया है कि कैल्साइट की एक पतली प्राकृतिक परत ने फ्रांस की शोवेट गुफा में 37,000 साल पुरानी पेंटिंग्स को वार्निश की तरह सुरक्षित रखा होगा। टीम ने नाज़ुक स्थल को नुकसान से बचाने के लिए लगभग ढाई मीटर दूर से काम किया, और मशहूर हॉर्सेज़ पैनल सहित कला के कुछ हिस्सों पर खनिज परत को यूवी रोशनी में नीला चमकता पाया। एसीएस ओमेगा जर्नल में प्रकाशित नतीजों से यह भी पता चलता है कि कुछ चित्र गर्म चारकोल से बनाए गए थे, क्योंकि मशाल के निशानों के पास नारंगी चमक मिली।
