(1) Why use gold? This would be a bit like
imitation MDF made out of burr walnut. |
|
| |
(2) Gold is soft - your diffraction grating won't
survive handling. |
|
| |
(3) The entire situation in Syria. |
|
| |
(5) Diffraction gratings as decoration are WKTE. |
|
| |
about (2) this differs from a surface diffraction gating, it is a bunch of layers, so polishing, sort of like silver polishing could leave it diffraction grating colored |
|

(1) I was looking for a discount mithril substitute! One of the benefits of a microstructured material could be overlapping # layers, sort of like a composite, creating adjustable, heightened strength, so it mithril-like outperforms other metals. |
|
| |
(5) are heaps of layers of polishable metal WKTE? um, perhaps otherwise. |
|
| |
(4) actually I am urging everyone to rummage through previous unpublished ideas, this is an old unpublished idea. I think more people putting things, even their old unpublished ideas on the .5b will be beneficial! |

Gold is a bad starting point. Gold is soft, ductile, and very dense. |
|
| |
"It could be beaten like copper, and polished like glass; and the Dwarves could make of it a metal, light and yet harder than tempered steel." |

Some Aluminium alloys come close to this specification; Titanium isn't easy to work, and oxidises rapidly, but surface treatments like anodization can help. But so far your puny Earth science hasn't developed anything like a proper mithril substitute. |

OK, maybe I don't get this. Are you talking about: |
|
| |
(a) Gratings (ie, regularly spaced ridges) on a gold
surface or |
|
| |
(b) Semi-transparent coatings of defined thickness,
deposited on the gold (like the coatings on modern
lenses that make them appear coloured when
viewed at an angle) |
|
| |
//Earth science hasn't developed anything like a
proper mithril substitute// Pah! Many small items
are sold in blister-packs made from a transparent
substance which is light, flexible and impenetrable
by all known implements. |

Next up, MaxCo Armoured Defence & Picture Framing Corp. present their new lightweight combat vehicle, which discards conventional plating and reactive armour in favour of a double layer of those damned plastic blister packs that inkjet cartridges come in ... |

The prototype has been ready for evaluation since
last July. Unfortunately, none of us can figure out
how to get into the bloody thing. |

Yes, or then again they might not. |
