Nitrotitanite Posted December 26, 2018 Share Posted December 26, 2018 For many it will seem a stupid question, I have to make blue and purple stars and for the first time I'm using potassium perchlorate and I was wondering if it was possible to grind it in a blender?Surely I would not do it with the chlorate I read that it can explode alone but the perchlorate is not correct or is it better to avoid?Are there any other precautions always remaining only with perchlorate such as measuring spoons for measuring plastic, steel etc ...?thank you Link to comment Share on other sites More sharing options...
Col Posted December 26, 2018 Share Posted December 26, 2018 Generally perc only needs to be passed through a screen. I mill my perc for some applications (not stars) using a dedicated mill jar with ceramic media and always on its own. Link to comment Share on other sites More sharing options...
Nitrotitanite Posted December 26, 2018 Author Share Posted December 26, 2018 the problem is that I can not find small enough screens even looking online here in europe, so the only alternative and the blender. If you use the perchlorate mill I should not have problems at least in theory:) Link to comment Share on other sites More sharing options...
Arthur Posted December 26, 2018 Share Posted December 26, 2018 Stainless screens and screen mesh is sold by Inoxia Ltd https://www.inoxia.co.uk/products/mesh/sheets?role=menuitem&tabindex=-1 He's in the UK but ships inert items with no problem.

OldMarine Posted December 26, 2018 Share Posted December 26, 2018 You can grind perchlorate but just be sure to clean the blender well before and after grinding. I did a bunch of it before I got a decent ball mill. Link to comment Share on other sites More sharing options...
Nitrotitanite Posted December 27, 2018 Author Share Posted December 27, 2018 Thanks now I feel more secure, my care will be to clean all the tools well to avoid any contamination.In the future I will have to equip the ball mill. Link to comment Share on other sites More sharing options...
evabrown Posted December 28, 2018 Share Posted December 28, 2018 Though I haven't enough idea about it, I want to say for grinding purpose don't use any Stainless steel cookware. Link to comment Share on other sites More sharing options...

dlking59 Posted December 29, 2018 Share Posted December 29, 2018 Though I haven't enough idea about it, I want to say for grinding purpose don't use any Stainless steel cookware. My 2 coffee grinders are Kitchen Aid with stainless cups. One for oxiders and one for fuel. I haven't used them yet. Are you saying I shouldn't use them and to get something else. I'm a little worried now. I do have one that is some type of acrylic or hard plastic bowl. Link to comment Share on other sites More sharing options...

While I am no expert, it is my understanding that individual chemical grinding should be fine, and be sure to wash between different chems, or better yet, get extra grinding bits for each chem. Never use such a grinder on mixed chems. Link to comment Share on other sites More sharing options...
dagabu Posted December 29, 2018 Share Posted December 29, 2018 The question you want to ask yourself is, do you want to have an oxidizer confined and heated up in your hand? What items make flash? Is there a fuel in that power trian? PTFE? Link to comment Share on other sites More sharing options...
