danehc Posted April 19, 2012 Report Share Posted April 19, 2012 I made my own masters from clay (baked in the oven) and the molds were made off of that master out of oomoo. I pour my plastics with no color added, only glitters, but my clear always comes out frosted. I sanded the master smooth with a very fine sandpaper, but i have not sealed it with anything. Is it my oomoo mold or the clay master? Thanks, I wish i found this site sooner! 2 Quote Link to comment Share on other sites More sharing options...
Travis Posted April 19, 2012 Report Share Posted April 19, 2012 It isn't the RTV silicone and if the clay should have cleared up after a few pours as the plastic picked up any fines left from the sanding of the master. What glitters are you using? Not all glitters are equal some of the craft stores will partially to completely melt and leave clear plastic with a frosted or hazy look to it.

carolinamike Posted April 19, 2012 Report Share Posted April 19, 2012 (edited) A lot of folks coat their mold with half water half elmer's glue. If you have a good and shiny cavity if it's still frosty looking then I would start leaning towards a plastic problem.

djs Posted April 20, 2012 Report Share Posted April 20, 2012 (edited) I would flame the bait with a propane tourch. This will bring back the shine/clear you are looking for if there is no problem with the plastic. There is many well known swimbait makers that use silicone to make the molds they use and they flame the baits to get the shine back.

wchilton Posted April 20, 2012 Report Share Posted April 20, 2012 If your master wasn't shiny, the silicone mold won't be shiny. I usually coat masters for my silicone molds with clear floor wax (several coats). Best finish for me is accomplished by dipping, draining off excess, and then can dry with a hair drier to speed things up. Be careful if your master is pourous (wood) as a hot hair drier will make the floor wax bubble and you have to start over. Has worked really well for me on baked clay.
