hi there, my name is Paul and have kept myself quite for about 6 months since there so much information on here its taken this long to get all the basics together, with the help here iv built my own star roller which i love rolling stars (so quick and fun), made fast bp, iv made and tested about 25 2" - 3" shells with different colour stars. but most importantly how you enjoy a dangerous hobby in a safe manner. so thank you so far

Anyway I'm trying to make Nitrocellulose Lacquer via ping pong balls and acetone, question i have is, Im mixing the two together and left overnight and nothing lol :blink:

. i know the acetone is 100% fine as iv tried for 2 diffent sources and was wondering if its posible the ping pong balls could be made from something diffent than normal.

anyone else had this problem

many thanks

Hi PyroPDC...

Glad to hear you are doing so well!

I suspect you are right. I think a lot of ping-pong balls are not made of NC these days. If they were, they would soften and collapse in the acetone within a few minutes.

I have a tin of genuine NC lacquer which I purchased a few years ago (used for restoring old guitars and motor bike petrol tanks I believe!) but not sure if you can still get this with the reduction in the use of solvents in paints. I think you can still get NC 'dope' from some model shops which is used for painting on the wings of model planes, and some people use this.

Glad it worked out for you...

Crackling microstars are a great effect. Just that some Chinese products over do it!

I often add a few to the end of a fountain so you get an interesting change of effect part-way though the performance.

Is it possible to use the commercial nc-lacquers ("Zapon lacquer", used for "glazing" wood etc.) as is in terms of their NC-content? Most formulas call for 10% NC-lacquer in acetone, so do you have to thin it out?

And if so, what do you use to thin it out? I saw some products which could be thinned out with alcohol, but this would not dissolve parlon to bind stars. Other brands call for a special thinner. I though acetone is the standard...

Acetone is standard yes and should certainly mix with whatever solvent may have been used if not already acetone.

I´m still unsure. Every NC-lacquer I find calls for cellulose thinner, which is hydrocarbon or ester-based. Acetone is a ketone.

Furthermore none of the lacquers seems to be acetone based, some are alcohol based, others based on hydrocarbons or esters... not sure if that matters but the pyro formulas seem to call for NC in acetone or amyl acetate.

Need help!
