Bigfatorange Posted October 7, 2020 Posted October 7, 2020 Hi I need to know if this is nitrocellulose lacquerhttps://www.rockler....322-01-1000.jpg If this if will it work well for bismuth trioxide crackling micro stars?
BetICouldMake1 Posted October 7, 2020 Posted October 7, 2020 I can't open the link but I'm guessing it's woodworking lacquer. If so, then it probably isn't good for our purposes. Typically NC made for crackle uses double based smokeless powder dissolved in acetone. The thinking seems to be that the nitroglycerin in double based powders contributes to the power of the crackle.
Bigfatorange Posted October 7, 2020 Author Posted October 7, 2020 Oh ok where can I get good NC for crackle
MikeL Posted October 7, 2020 Posted October 7, 2020 The link isn't complete. The middle part is missing. I haven't tried it yet but I picked up this at Stewmac - https://www.stewmac.com/luthier-tools-and-supplies/supplies/finishing-supplies/finishes-and-solvents/colortone-spraying-lacquer/colortone-nitrocellulose-guitar-lacquer.html
BetICouldMake1 Posted October 7, 2020 Posted October 7, 2020 Double based smokeless powder dissolved in acetone...
Bigfatorange Posted October 8, 2020 Author Posted October 8, 2020 I cant buy smokeless but is there some NC that is ready and that works well for crackles
Pyrophury Posted October 8, 2020 Posted October 8, 2020 I cant buy smokeless but is there some NC that is ready and that works well for crackles Smokeless powder is not necessary for making crackling stars, NC lacquer with high solids (20%) will make excellent crackle. Here's an example of some I made with just such lacquer: 1
Bigfatorange Posted October 8, 2020 Author Posted October 8, 2020 Can you please show me what lacquer you used?
Pyrophury Posted October 8, 2020 Posted October 8, 2020 It was just a 250ml can of generic unbranded clear gloss guitar lacquer.
Bigfatorange Posted October 8, 2020 Author Posted October 8, 2020 It was just a 250ml can of generic unbranded clear gloss guitar lacquer.Ok would you be able to give me a link because I cant seem to find it online
Pyrophury Posted October 8, 2020 Posted October 8, 2020 Ok would you be able to give me a link because I cant seem to find it online I got it off ebay a long time ago, it's no longer listed. I doubt there's that much difference between most NC lacquers, they're all probably around 20% solids.
Bigfatorange Posted October 8, 2020 Author Posted October 8, 2020 Oh ok would this work because Im not sure because it have some additional additives https://www.woodworkingshop.com/product/m6101406/?inMed=GSTORE&dfw_tracker=18711-M6101406&gclid=Cj0KCQjw8fr7BRDSARIsAK0Qqr5EopNDSiUrfiErm_xWcWiqNZItCJQ9y9bgAtmkuYPkQIJxqaZ7daUaAijHEALw_wcBSDS sheethttps://www.klingsporwoodworking.com/pdfs/M6101406.pdf
SharkWhisperer Posted October 8, 2020 Posted October 8, 2020 (edited) It will work. Expensive for what you get. And you'll be limited to lighting individual crackle pieces with a torch or tossing them in the campfire if you don't have ingredients for a prime--they are very difficult to ignite, usually require troubleshooting beyond your experience, and will definitely blow blind in fountains and mines and shells/stars if they are not thickly primed. Do you have components and knowledge to do this yet? Safely? What are you going to put crackle stars in? Most fountains are BP based. Many stars are BP based. Lift for mines is BP. You won't even have a way to realistically test them in motion without BP for lift/burst/prime/matrix. So instead of getting way ahead of yourself, at decent expense, perhaps learn how to safely make BP first? Many if not most pyro project doors are slammed shut in your face without having this basic skill. And you're 15 years-old, which means you cannot buy commercial BP (will your Mom buy it for you? Doubt it). You've double-posted on this topic and even started another with ping-pong ball NC. That says you have not searched the forum and read all of the threads that already address almost every NC issue possibly imaginable in great detail. And No-NC crackle. You are completely new to pyro and appear to be getting ahead of yourself with sensitive crackle mixes instead of learning the foundations first. It will definitely prove to be a moderately expensive first failure for you, and possibly a dangerous one. Edited October 8, 2020 by SharkWhisperer
rogeryermaw Posted October 8, 2020 Posted October 8, 2020 a can of this and some acetone will get you where you wanna go.
