woodsac Posted November 25, 2004 Report Share Posted November 25, 2004 What are you stirring the plastic with? Try using something metal to stir with. Wood releases moisture into the plastic and causes bubbles. Quote Link to comment Share on other sites More sharing options...

woodsac Posted November 25, 2004 Report Share Posted November 25, 2004 Hmmmm... What are your molds made out of? Some of the guys have had problems with plaster and air bubbles. I think it has something to do with not coating the mold? I don't use plaster, so hopefully one of them will chime in. Quote Link to comment Share on other sites More sharing options...
alsworms Posted November 25, 2004 Report Share Posted November 25, 2004 Jake hit the nail on the head, but if your stirring tool isn't doing it, then I'd say you probably have some moisture in your plastic. Are you pouring out of a cup? Is it just the first few baits that have bubbles? If so, you need to cook it a little more to let the bubbles dissolve before pouring. Bubbles rise to the top, so your first few baits will have bubbles if you don't cook enough when pouring from cups or pyrex. Also make sure your plastic is well-sealed. Screw the lids on super tight and don't let the plastic take in air any more than necessary. Don't cook the plastic too fast. Extreme heat will make the plastic bubble and it will not gel properly. Somewhere between medium and high heat is perfect. Some scents will make the plastic bubble too. For some reason, I have a problem with Lure Craft's garlic doing that. Same thing goes for some of Pro Cure's bait sauces. If I'm off on any of these, let us know. There are a ton of guys here who can help.

njbass Posted November 25, 2004 Author Report Share Posted November 25, 2004 I am using a stove and a pouring pan. I keep the flame at low. I am using plaster molds, and i used modge podge to seal it.almost all of them have air bubbles. Thanks jake Quote Link to comment Share on other sites More sharing options...
alsworms Posted November 25, 2004 Report Share Posted November 25, 2004 I'm not familiar with modge podge. I'm sure some of the other members can help with that. I coat plaster molds with polyurethane spray. If all your baits have bubbles, then it's back to the molds. My best guess is the bubbles in your plaster (air pockets) are causing the baits to bubble. If you make your own plaster molds, pour the water in first, then add your plaster accordingly. I haven't made plaster molds in a long time, but that always seemed to solve the bubbling problem for me. Also......after you pour your plaster, lay the pan on a flat surface and tap it repeatedly to force all the bubbles to the top. They should dissolve within a few seconds from there. Don't coat your plaster molds with anything until it's completely dry. Let us know if we're getting close. Chris Quote Link to comment Share on other sites More sharing options...
BassnG3 Posted November 25, 2004 Report Share Posted November 25, 2004 Chris what brand of spray do you use?? Scott Quote Link to comment Share on other sites More sharing options...
Senkosam Posted November 25, 2004 Report Share Posted November 25, 2004 Chris had the best answer. Wood will force bubbles out of it, but moisture is th biggest culprit. Once the hot plastic settles and the surface plastic is poured off, few bubbles will be in the rest. Sam Quote Link to comment Share on other sites More sharing options...
