The witness plates nicely complement my sand crushing test result, which indicated that the mix has roughly 88% higher brisance compared to pure double salt. As can be seen 0,5g DS left almost identical damage compared to 0,25g mix. Though it is not correct to compare sand crushing results to witness plates, the underlaying patterns do match quite well.

ETN is much less sensitive on friction than SADS. Therefore is my idea, create mix, with maximum content ETN, which is still possible reliable detonated in solid cavity. I recommend ratio for example 1:1 and try it. Mixing both under acetone and after from this create some grain on sieve 1 x 1 mm. For filling cavity. Output segment can be from 0,25 pure ETN. DDT segment from 0,15 ETN + 0,15 SADS. Advantage is, that at filling cavity we not use pure and sensitive as classic primary, but less sensitive mix. Dr.

Silver acetylide has quite high sensitivity to static electricity, perhaps this might help address this?
Quote:

This invention relates to a process for reducing the sensitivity of primary explosives to initiation by electrostatic discharges, and to a primary explosive composition having a reduced sensitivity to initiation by electrostatic discharges by virtue of the combination therewith of a polyol polynitrate of low sensitivity, such as trimethylolethane trinitrate, in a small amount.

Boom.
The explosion removed the windows, the door and most of the chimney.
It was the sort of thing you expected in the Street of alchemists. The neighbors preferred explosions, which were at least identifiable and soon over. They were better than the smells, which crept up on you.
-Terry Pratchett, "Moving Pictures"

It is essential that persons having explosive 
substances under their charge should never 
lose sight of the conviction that, preventive 
measures should always be prescribed 
on the hypothesis of an explosion.

From what I can tell by handling it, the SADS:ETN (80:20) is indeed somewhat less sensitive to static electricity than pure SADS. I'm not sure how to quantify it though.

Bonus tip: I realized that I could add some methanol or isopropanol to the water in the calcium carbide acetylene generator, in order to help control the foaming.

hmm

What LoL is proposing should certainly work, but the issue is if this goes of the primary is now 4-8 times more powerful resulting in some bad damage.

It is interesting, but LoL, CHP works fine.

75mg of SADS fails to kick off PETN sometimes... so this could be a real help to that.

Of course, that CHP is during manipulation almost "indestructible" against SADS. But it is another thread. I also recommend CHP, than trouble with sensitivity SADS....:-)

Nice idea to use alcohols as a foam killer...suds depressant.

A layer of organic oïl on top (0,5-1cm) or of benzine/ether/petroleum ether will do aswel ;)

CHP seems like nonsense since the starting perchlorate is quite sensitive primary and you won't (likely) be making small mg size batches like with SA.DS plus the amount of handling during CHP synthesis is quite large. That's similair to the situation with NHN, where some hail it as a work of god, yet they fail to remind that NHN is among the most static sensitive primaries or that un-dextrinated lead azide is more sensitive to friction than HMTD and faar faar more sensitive to friction than TATP/DADP. It's like dangerous boasting about ones ability to get the right chemicals (being a grown up with tons of NaN3 in the chems room). In the end of the day you still need remote handling, large pieces of paper with small amounts of said primary, blast mitigation devices, cotton wrapped sticks and many layers of body protection.

Would it be possible to use another acid instead of HNO3 to create the needed acidic conditions? I mean, would a few drops of sulphuric acid be enough? It (the sulphate) should be possible to wash it from the filter.

First part...
What starting perchlorate into CuHexP (Copper hexamine perchlorate) is a primary? NH4ClO4 or Cu(ClO4)2?
==> Not into this world sorry

Second part...
Your question is unclear what are you refering to? SADS, CHP, CTAP, HMTD, else?

I was talking about Dr. Liptakov synthesis on Vimeo, where he uses 10 g of TACP to synthetise CHP - I was pointing out that this TACP is quite sensitive and handling 10 g of it is simly too big of a risk (even though you might handle it in its not completely dry state). The fact that CHP is quite unsensitive should not lure anybody to directly handle/store 10 g of TACP. It requires somewhat more of a work than making SA.DS or lead azide, so a person is tempted to go into the gram scale, rather than to quickly make 400 mg of SA.DS or LA for use in blasting caps. If you use another route, without the TCAP step and in small quantitiy, than yes .. it is indeed a workable solution.

SA.DS - I understand that the nitric acid should be ideal due to the common ion effect, making the precipitation of SA.DS easier, but would it be possible to avoid the use of HNO3 and use something else instead .. like a few drops of sulphuric acid, has this been tried out?

I have handled much much more than 10Grams of TACP at a time, but have not stored it of course. The point it, it is not a primary explosive, it can be treated like PETN. Look, CHP is the best around, unless you can come up with another DDT system. Of course, there are main charges that are safe and can DDT from just a blackpowder cap... but those are kind of a secret of mine, but now you know, they are out there! Also, there are several AN mixtures that 2grams of flash (even confined in plastic) will bring to full orde Report back to us, but trust me, you don't even need a primary :). I can say this because I have invented a complete binary system... including the det

Has it been confirmed? I mean, is this true for the average crystal modifications? I was under the impression that TACP is about average primary (from impact test on youtube) and that CHP is at the level of ETN/PETN ..and..with very low friction sensitivity. If so, than I stand corrected. We're little bit OT.

Primary substance is too broad a concept. They should be divided into at least 3 degrees. Depending on the hazard for general (laboratory) handling. Example: 3 = FHg..... 2 = Lead Azide, (next?)...... 1 = TACP, CHP, NHN (next?)...... 0 = TACN. (ETN? MHN?) ETN is between primary - secondary edge? If someon said, that This is primary, Is it as say = she is the Witch! You all are an Witches!

The problem is that there is no real correlation between friction, impact and static sensitivity. NHN is quite friction/impact insensitive, but it's static sensitive (I think). Undextrinated lead azide, esp. the beta modification is very sensitive to friction...from the prof. tested ones.. only DDNP seems to be good in all 3.. IIRC.... ETN is 5× less friction sensitive than MF.. that's slightly into the secondary cat, no real static problems
