Glassworkers would then purchase this solid glass, re-melt it, and craft it into vessels and other wares.<\/p>\n\n\n\n<p>Various types of glass were manufactured, but the most prized may have been Alexandrian glass, described by one ancient writer as &#8220;colourless or transparent, as closely as possible resembling rock crystal.&#8221; Glassmakers achieved this feat by oxidizing the sand&#8217;s iron from blue Fe2+ to pale Fe3+ by adding antimony oxide. The glass offered a blank slate for decoration and was sought after for serving vessels. The glass&#8217; name hints that it hailed from Egypt when it was a Roman province (the capital was Alexandria), but its precise origin has remained elusive to historians.<\/p>\n\n\n\n<p>[ <a href=\"https:\/\/www.realclearscience.com\/quick_and_clear_science\/2020\/07\/13\/where_did_romes_famous_alexandrian_glass_come_from.html\" target=\"_blank\" rel=\"noreferrer noopener\">click to continue reading at RCS<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from Real Clear Science Where Did Rome&#8217;s Famous &#8216;Alexandrian&#8217; Glass Come From By\u00a0Ross Pomeroy Two thousand years ago, the Roman Empire was cranking out glassware unsurpassed in intricacy, beauty, or design, with skill and efficiency that wouldn&#8217;t be topped until the advent of modern industry in the 18th century.\u00a0Large production operations scattered across the empire [&hellip;]<\/p>\n","protected":false},"author":26,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[3],"tags":[],"class_list":["post-10830","post","type-post","status-publish","format-standard","hentry","category-culture-art"],"_links":{"self":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts\/10830","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/users\/26"}],"replies":[{"embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/comments?post=10830"}],"version-history":[{"count":0,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts\/10830\/revisions"}],"wp:attachment":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/media?parent=10830"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/categories?post=10830"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/tags?post=10830"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
