Ubehage Posted October 25, 2014 Share Posted October 25, 2014 I found a page on this site, with a lot of recipes for pyro-stuff.In the part where the Veline-compositions are described, it says "Do not tamper the composition!"So, what is tampering? And can the Veline-comps be pressed? Link to comment Share on other sites More sharing options...
MrB Posted October 25, 2014 Share Posted October 25, 2014 "Tampering" = Improvising changes. Meaning, stick to the numbers.B! 1 Link to comment Share on other sites More sharing options...

enanthate Posted October 25, 2014 Share Posted October 25, 2014 Maybe it's a safetything.Honestly i adjusted one of the colors to improve it, and there was room for improvement. Link to comment Share on other sites More sharing options...
MrB Posted October 25, 2014 Share Posted October 25, 2014 Room for improvement? Yes, if getting brighter stars, or "stronger" colors is what is sought after. But the Veline system isn't about making the "best" green, or what ever. It's about providing a color system where the different stars go well with one and other, so you ca mix and match without worrying that one will over power the other. And of course being chemicly compatible you don't need to worry about putting one near another, and expecting weird reactions. If you want the best red/green/purple/blue and so on... They are elsewhere to be found.Veline is just easy to use, reliable results, and not THAT expensive... To bad perch is getting extinct in Europe. Thats going to change the pricing.B!

AzoMittle Posted October 25, 2014 Share Posted October 25, 2014 Do not tamper the composition could also be translated into dont hit it with a mallet.Its always safer to press star comps that contain metals. What do you mean by this? Is it specific to certain oxidizers or something? I have been whacking away at wetted nitrate/metal compositions in a brass rammer with a mallet for the past year and haven't had any incidents. Which isn't to say it isn't dangerous, just that I havent' had any. Is this something I should stop doing? 1 Link to comment Share on other sites More sharing options...
Col Posted October 25, 2014 Share Posted October 25, 2014 (edited) Star comps with a high percentage of metals creates more opportunity for friction between the metal particles. A brass rammer wont make much of a difference safety wise if the star comp is semi crunchy with MgAl Given the option. it`s always safer to press any comp that contains metal. An accident only needs to happen once. Edited October 25, 2014 by Col Link to comment Share on other sites More sharing options...

An accident only needs to happen once. Let me try to understand exactly what you say - comps with MgAl is generally safer to ram than any metal-comp without MgAl?

Milyan720 Posted October 26, 2014 Share Posted October 26, 2014 (edited) Anything with chlorate in it is sensitiveEven though I purposely tried to set off a small amount of h3 in a mortar and pestle and with a hammer, nothing happenedI'm not saying it isn't sensitive though Edited October 26, 2014 by Milyan720 1 Link to comment Share on other sites More sharing options...
