Using acetone to make cut veline stars

[insutama]

Would i be able to cut one of the veline coloured stars by using acetone seeing how there is parlon in the formula ?

If so about how much acetone should i use i was thinking start at 20%.

I was gonna use the baggie method to wet my composition and roll it to size.

any suggestions ?

Ad acetone to where it starts to behave like playdo. If your not done whit it just keep on pouring to that point you are satisfy.

I like parlon stars, and have found that different compositions take different proportions of acetone to bind properly. For example, stars that develop color from carbonates rather than nitrates use less acetone to bind. A 500g batch of stars will take from 100-250ml of acetone to bind, depending on composition.

 

The gap between "not quite enough" acetone and "whoops, too much" is pretty thin. I use double-gloved hands to work the acetone into the comp in small amounts - I start with an ounce or two at a time for large batches, and end up adding a few drops at a time to achieve the proper consistency. It should hold together without significant breaks around the edges, but should not be shiny, or extrude liquid when at rest. If you get it too wet, wait a bit and keep working it - acetone evaporates quickly.

 

Keep the rolled-out comp covered until you're ready to cut it. If it gets too dry it tends to crumble rather than cut.

awsome thanks guys

how about prime whats a good prime to use when making cut coloured rubber stars

[Arthur]

Depending on any incompatibilities -which you have to know! dust the rolling board with prime and roll out the moist patty then cut the stars and sprinkle prime straight onto the still tacky composition. Sometimes a fine BP works, sometimes a BP with added silicon is hotter and more successful, Just occasionally you have to step prime with a hot prime on the star and then a BP prime over the hot prime. Sometimes a rough star surface is enough, stars with a rough prime layer take fire well.

okay great thanks ill try my pinball prime see how that works

Like rolling pastry, cover the board and the top of the patty with prime, enough should stick as the patty passes through wet to tacky to firm and to dry.
