Pop Posted July 10, 2005 Report Share Posted July 10, 2005 Before I do something stupid, I figure it is better to consult with everyone. I bought a plastic measuring cup that has a beautiful pouring spout that I figure will do a great job pouring into small areas. I checked with three authorities (women) if this cup can be used in a microwave and got a posetive answer from all three. However they know nothing about plastisol. Will the plastisol effect the plastic cup? Should I not use the plastic measuring cup? Where did I purchase this cup you ask, Walmart ofcourse. Thanks, Pop Quote Link to comment Share on other sites More sharing options...
nova Posted July 11, 2005 Report Share Posted July 11, 2005 Plastisol will "eat" styrene. You should play safe and buy different sizes of pyrex cups. You can get them in 1 cup; 2 cup; and 4 cup sizes. Quote Link to comment Share on other sites More sharing options...
redg8r Posted July 11, 2005 Report Share Posted July 11, 2005 other than chemical compatibility, a bigger worry should be HEAT. remember you'll be adding plastisol to that cup at the same temperature as grease in a deep fryer (@350) I dont know too many plastics that wont melt under that temp. Polyester, nylon & teflon are the only ones I know. regardless, spring for the borosilicate (pyrex is a brand name) glass. i know its a shame you wont be able to use the nifty spout, but it might save you some serious burns.

nova Posted July 11, 2005 Report Share Posted July 11, 2005 Jerry there is a new plastic out that you actally bake with in your oven.I don't know the name of it though. Quote Link to comment Share on other sites More sharing options...
Pop Posted July 11, 2005 Author Report Share Posted July 11, 2005 I already use the pyrex cups. Just really liked the nifty spout. You are probably right though. Oh well, I had hoped. Pop Quote Link to comment Share on other sites More sharing options...
dvowell Posted July 11, 2005 Report Share Posted July 11, 2005 When I first started pouring, I bought the pyrex...but found cups exactly like you are describing. I decided to do a little test and put some old plastic in the cup and added a dash of new...and started micro'ing it. It looked like things were going to be o.k., but I put on a heat resistant glove (the type welder's use) just to be safe and started pouring. The spout was great...but the bottom of the cup fell out spewing hot plastic out the bottom. Just like I expected. In short: Don't do it. Your skin will thank you. -Danny Quote Link to comment Share on other sites More sharing options...

I think your thinking of silicone baking pans. the ones you can roll or fold up for storage? Quote Link to comment Share on other sites More sharing options...
nova Posted July 12, 2005 Report Share Posted July 12, 2005 Possible. I just remember seeing something on the tube about it. Quote Link to comment Share on other sites More sharing options...
saint308 Posted July 12, 2005 Report Share Posted July 12, 2005 Everyone talks about Pyrex, I use two currently. However, I asked my wife to go buy me a small cup from Wally world; and she bought an anchor brand cup. Will this work the same as pyrex? I read about it somewhere on here a long time ago, but don't remeber and can't find it. Please help before I scorch myself. Thanks as always. Saint.

WVaGitzit Posted July 12, 2005 Report Share Posted July 12, 2005 I am a more of a chemist than I am a lure maker but I can tell you that the anchor glass will work. What makes Pyrex the best for this type application is that it will not crack from temperature changes. Most glass including the anchor will break if the temperature changes too rapidly. It is most likely to happen if you cool it down too quickly. The pyrex glass can be 350 degrees and put in cold water and won't break which is why is works so well for this you don't have to worry about it. I hope this answers your question.

nova Posted July 12, 2005 Report Share Posted July 12, 2005 I have one pyrex and two anchor cups. I did have one anchor explode on me a while ago and I figured it was from rapid change. So' I now use old Lurecraft molds as a pad to set the cup on when it comes out of the micro. Works great. :idea: Quote Link to comment Share on other sites More sharing options...
