Very nice indeed. I am not that much into art, but I can see how this would have a lot of appeal from an artistic perspective.

Nice golden hue should have, brass plate.
Nice colors should have with heat treated steel sheet.
Interesting would be, copy of images generated with 3D printer and print in sheet metal as detonography.

Small goods.
Annealed copper 0.55 mm, distance 50 mm, 12 g NM gelatin, water udder. This set goes to a mechanical press. An attempt was made because: It is
necessary to determine the possibilities detonography. The greatest effect is natural leaves, corn and the like.

Ahh...exquicite work!! I take a deep bow to your choice of test object. I have always been facinated by ferns. Primordial entities, primitive, yet so
perfect and compelling in their form. There is a legend in my country about the mysterious and elusive fern blossom...a rare occasion of wonder that
is believed to accompany the brief passing of midsummers nights when Dusk and Dawn meet to embrace each other for a brief moment to express their
undying and everlasting love for each other and then venture apart again for another year to be separated by the dark void of night. It is said that
the one who finds the fern blossom in this magical moment may make any wish and it will be granted. And so young people, who still belive in wonders,
venture into the forest to look for this elusive cause at every midsummer celebration. I do not know of any who have found the elusive wishgranting
blossom, but I do know of many who have found strenght in the idea to make their dreams and wishes come true. I hope that people always keep looking
for the wonders around them....for once you close your eyes to the magic, it is forever lost and so with it all the dreams that could lay ahead.
Exact science is a figment of imagination.......

Detonography
Markx: Fern is fascinating, has a very fine structure.
For SK: That's a very interesting idea. Non-Newtonian Fluid / Cornstarch and water. When used as a dense mass of dough. Gips and water work.
Cornstarch Watergel (non explosive of course) will be better. Very good idea. Or any other kind of dough. Maybe dough of wheat flour. (Girlfriend will
kill me)
Markx: You would have to try out the dough ...![:D](./images/smilies/biggrin.gif)

Very nice.
Can you explain how your NM gelatin is made?
I have NM and I'd like to have something to cast in shape that's not so liquid.

This?

Nitroglycerin with at least 15% nitromethane, the NM de-sensitizes the NG and lowers freezing temperature- Then gel with nitrocellulose and use to
make various dynamites as usual, of course accounting for reduction in Oxygen.

nitromethane gelatin
Nitromethane gelatin: NM 81% + NC2 15% (cont.12,4%N) + 3% Al (use silver flakes for color, no dark german, no spheric) + 1% microballoons. It is
better to use not NC2, but gunpowder containing nitroglycerin. In this case gelatin is extremely dense, like jelly. All components, their
representation can vary widely. For example, Aluminium 3-20%, NC 6-18, microballons 0,5- 3%. Initiation No.8-10. Attention, gelatin is rapidly losing
nitromethane content. Within a few hours. The charge must be gas tight. Hermetically sealed... ...LL

Try this article. the composition described within is probably just what you are looking for. i have tested it myself and found it to be quite
satisfactory, especially with added metals both aluminium powder and titanium powder which produced a rather thermobaric like effect.

PLX variant made with 5% ethylenediamine sensitizer and 5% a cab-o-sil type thickener?
The PDF refers to the thickener as "Code #1". And mentions several other products as code #2, code #3...
I've access to several types of fumed silica, used for thickening resin, as a bulking and anti caking agent in powders, etc. Manufacturers categorizes
them by several characteristics-
Any clue what type/manufacturer's designation the mysterious "code #1" might be?

How is sensitivity at temperatures down to -30C? Does this detonate when frozen, -29.2 is NM's freeze point.
Which type of microballoons- Plastic? Glass?

Sensitivity at -30˚C? No tested. Tested only -5 C, full det. Laboratory of Liptakov not above the Arctic Circle. Fortunately. Glass microballoons,

not too sure what code 1 may be. It could be any number of things. It would have to be something cheap since they wanted to blanket mine feilds with
the stuff. I tested it using nitrocellulose as the gelling agent and it suspended the metal powders nicely which was all i aimed to do in that
instance. Although fumed silica would probably work well i did not want to add inert ingredients other than the aluminium/titanium powders for that
particular test

The description of use looks like hydrophilic fumed silica, 5% is a typical ratio for gelling liquids.
The chemical analysis looks... Like diatomaceous earth? The variability of composition (and low price, if they were going to blanket whole fields with
it) makes me think it's a natural product.
Beyond that, there's probably other candidates I have not thought of.

14. All the materials used in the preparation of the newly developed gel are readily available on commercial scale. Code No.1, the only new
ingredients introduced in this report, is commercially available at moderate cost. Chemically, it consist of 93-96% colloidal SiO2, + 2,5-3,5 Na2SO4,
+ 1,0% Al2O3/Fe2O3 + 0,5 to 1,5% volatiles at 800C (300?) (for 1/2 hour). No evidence of nitromethane decomposition due to the presence of Code No.1
has been observed while in storage at ambient temperature for three months or more.
This means that the composition prevents Code 1 (strongly limits) evaporation of nitromethane? I do not believe too. We can only try... ...LL

No!
It means that the colloidal SiO2+... (kind of silica-gel) loses 0.5 to 1.5% of its weight upon heating at 300 (or 800) °C...thus this fraction is
called volatiles and is more than certainly composed of water; silica-gel being used as dehydratant in food industry packages (tiny pockets with "do
not eat" written on it), in electronic devices packaging and in some organic lab dessicator beads (that can be reused/recycled by oven
heating...hydratation level is indicated by cobalt salts passing from yellow-pink when dry to blue when hydrated) ... a few years ago it has also
found use as luxe kitten-bac filling (cat litter).

I have some experience with various silicas as they are of great importance as catalyst support. Colloidal silica generally refers to solutions of
fumed silica which is kept from clustering and clumping out usually by making the solution mildly alkaline (pH~9 if I remember correctly). Fumed
silica is itself commercially available, but the stuff is HORRIBLE to work with because of it's ridiculously low apparent density. It's a bit like
goose feathers, just much smaller and you need bags full to prepare a solution... that's why people prefer to work with the colloidal solution
versions. A popular brand of colloidal silicas is the LUDOX range made by Grace Industries (brochure attached). Another maker, off the top of my head
is Evonik (formerly Degussa).
The silica gel we commonly encounter in drying sachets, kitty litter and the like is quite a different thing morphologically speaking and doesn't have
the same rheological properties as fumed silicas. The former is prepared by acidification of sodium silicate followed by ageing regimes.

Fumed silica is also commercially available in a more expensive hydrophobic form. In this type, the surface has been 'silanated' (treated with a
mixture of methylchlorosilanes AFAIK) so that the naturally hydrophilic hydroxyl surface groups are replaced by methoxy groups.
***
PS. The picture on the front page of the brochure I attached is irrefutable proof that chemtrails are made by spraying SiCl4 into the turbine exhaust
from airplane engines, i.e. making fumed silica and HCl ![:D](./images/smilies/biggrin.gif)

We used the hydrophobic variety of fumed silica for an anti cake agent in pyro. I recall Cabot making product used in fireworks flash powders. Have to
dig for references- There are a lot of different grades by surface area and surface treatments.
Yes, the stuff is a pain to handle or mix with liquids, not so bad for solids. We just shoveled it in for last 20 minutes when milling the
Oxidizer/catalyst ingredients of a flash mixture. Ball min would then be full to the top, but the cab didn't keep the charge from rolling properly. 20
minutes later, there was a lot of decrease to the apparent bulk of the charge, and the mixture poured almost like water.
I note that code #2 and code #3 call for parafin oil as a mixing aid into nitromethane. That sounds like a treated product?
