Each paperweight contains two pennies, one minted before 1982 and one since.\u003c\/p\u003e\n\u003cp\u003eIn 1982, the US Treasury reduced the penny's copper content from 95% to 2.5% as a cost-saving measure. Modern pennies are primarily comprised of a zinc core with a thin copper coating. When exposed to the high temperatures of molten glass, the zinc melts, then boils, transforming into a galaxy of metal-plated bubbles. The older penny remains intact due to the higher melting point of copper. The Two Cent Paperweight is a manifestation of Michael's experiments at the intersection of science and aesthetics. \u003c\/p\u003e\n\u003cp\u003eThis faceted version allows for a play in the optics of glass which causes the internal elements to appear smaller and larger depending on your viewpoint.\u003c\/p\u003e","brand":"Michael Stern","offers":[{"title":"Default Title","offer_id":48952782618843,"sku":"A-TwoCent-Faceted","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0284\/5036\/files\/IMG_0185.jpg?v=1786829672","url":"https:\/\/store.urbanglass.org\/products\/two-cent-paperweight-with-a-facet","provider":"UrbanGlass","version":"1.0","type":"link"}
