I was reading an interesting article.
https://techcrunch.com/2017/04/25/greg-mark-of-markforged-talks-about-putting-metal-into-the-microwave/?ncid=rss
He is using Cad to produce components by “sintering” using metallic power to fill a form or sculpt a piece then heating it up until the particle fuse together.
In it he describes how fine particles of metal absorbed microwaves instead of reflecting them and how once hot they could carry on absorbing microwaves until a higher temperature is reached.
Would that not be a fine way to handle platinum black if you combined that process with some insulation bricks in a vacuum furnace?
