2 I've created a new attribute - GTIN . All I want to do is import my barcodes into the GTIN field per SKU . sku,additional_attributes AM0005930-34,gtin=08033546253915 I've created the above .csv , but the import says all my rows are incorrect. Can I not import my barcodes this way? My attribute is a text field . Surely Magento 2 can support this? magento2 attributes import share | improve this question edited 26 mins ago Shoaib Munir 2,027 1 8 28 asked May 2 '18 at 11:03 ...

4 $begingroup$ We all know where iron comes from.... but as I am reading up on supernova's it got me wondering why there is as much iron as there is in the universe? Brown dwarf's do not deposit iron... White dwarf's do not deposit iron... Type I supernovas leave no remnant so I can see where there would be iron released. Type II leave either a neutron star or black hole. As I understand it, the iron ash core collapses and the shock wave blows the rest of the star apart. Therefore no iron is released. (I know some would be made in the explosion along with all of the elements up to uranium. But would that account for all of the iron in the universe?) Hypernova's will deposit iron... (but they seem to be really rare) Do Type I supernova happen so frequently that iron is this common? ...
