ChloRure Posted October 22, 2012 Posted October 22, 2012 Hello! I want to do some dragon eggs soon, so I ordered some lead trioxide (bismuth was not available)... and now I am a little confused with the nc lacquer parts. I ordered 250ml nc lacquer from a pyro supplier (a little syrop mostly clear) and it doesnt say anything about % on the bottle. On the formula I was looking they ask for 10% NC. Do I just mix the CuO, Lead, Mgal and then add 10 grams of my lacquer to the mix (if doing 100g batch) ?? Do you have to add acetone to it ? I mean just wet the comp with the nc and cut them ? Thanks * Oh and this question is the same for all formulas that requires NC I suppose.
pdfbq Posted October 22, 2012 Posted October 22, 2012 I do not find it easy to make dragon eggs. I got the best result with home made 10% nc lacquer. So 10 gram of NC with 100 gram of acetone. I think you add as much NC laquer untill you get a nice putty like substance. Then try to make your stars as hard as possible.
burningRNX Posted October 22, 2012 Posted October 22, 2012 (edited) Evaporate 10 grams of the solution and measure the weight of the leftover NC, then you know the concentration. Edited October 22, 2012 by burningRNX

Algenco Posted October 23, 2012 Posted October 23, 2012 most likely it's 10%, any higher and it would be stiff
pyrodundee Posted October 23, 2012 Posted October 23, 2012 about to have a go myself at making some dragoneggs - if the concentration of NC isn't right, can the eggs be reworked with more NC lacquer after being dried ?? - figured the extra acetone would just evaporate off leaving an increased conc of NC?
ChloRure Posted October 23, 2012 Author Posted October 23, 2012 I think they will take longer to "pop" if you use too much NC. So for dragon eggs, just mix the dry chemicals toguether then add 10% of my NC laquer and with glove I try to incorporate the solution then make a paste and cut them right? No need for acetone in that ?
rveline Posted November 17, 2012 Posted November 17, 2012 My experience has been that the higher the nc content, th less loud the crackle, so more acetone and less nc laquer should give better results. You should be able to re-dampen the leftover crumbs with acetone or even finished stars, and remake.
