bass4cache Posted January 10, 2005 Report Share Posted January 10, 2005 So Im wondering if anyone else has sparks in the Microwave every once in a while? I havent figure out whats doing it. At first I thought it might be the glitter? But that doesnt seem to be the location of the arc. Doesnt arc in my old nuker, but only in my new one. What could it be????

woodsac Posted January 10, 2005 Report Share Posted January 10, 2005 The only time I've ever heard of this, it's caused by the metal flake found at craft stores. Are you remelting old plastics? Did you buy your flake from somewhere other than a supplier of flake for plastic baits? Quote Link to comment Share on other sites More sharing options...
Delw Posted January 10, 2005 Report Share Posted January 10, 2005 I am not saying your doing this so dont take it wrong, but you dont have the metal spoon or knife still in there do you? I had one guy that had the same problem and it turned out he left the spoon in there. A few other things to check make sure that the container you are heating up in has no metalic paint or linings Delw Quote Link to comment Share on other sites More sharing options...
woodsac Posted January 10, 2005 Report Share Posted January 10, 2005 Good point! I've seen generic type pyrex cups that have a thin metal band around the top of the glass, just below the pour spout. Quote Link to comment Share on other sites More sharing options...
Delw Posted January 10, 2005 Report Share Posted January 10, 2005 You know I just thought of another thing , That I should have remembered. A long time ago there was a post either here or on taklemaking(when it ws running) that a guy had a problem with silver glitter in his microwave. others did not. then a few other guys posted about seeing this at one time or another as well. Glitter is bright and shiny and it will refleck light or microwaves at some point, so if your using alot of glitter that might be something to look into. something to think about. If its arcing in one microwave use the other. Since melting plastics in a microwave is relitvely new, ther are some problems that some people are having this could be one of them. Another one is a microwave will trap moisture and cause your plastic to bubble in some real rare cases (usually when there is high humidity). what happens is that a mcrowave cooks so fast it traps moisture.

bass4cache Posted January 10, 2005 Author Report Share Posted January 10, 2005 Nope nothing but the Pyrex in the Micro. It must be the silver cuz now that I think about I think it is when Ive used silver flake. All of my flake if from Senkosam or Lurecrap. Ive also wondered about conaminents from other sources. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
GB GONE Posted January 10, 2005 Report Share Posted January 10, 2005 My small (0.008) Lurecraft silver causes my micro to arc!!! It was like pouring rocks in the lake anyways...real heavy!!! The small (0.008) red from LC bleeds like a stuck pig also.... lucky I got both of those for free, otherwise I might be talking bad about LC !!

Senkosam Posted January 11, 2005 Report Share Posted January 11, 2005 I had the same problem with some hologram glitter I ordered from one distributor. If the flakes where sitting on top of the plastic as it was melting, they would spark and flame. I sent back 10 lbs. and chewed him out since I specifically said, "for microwave use", before I ordered it. He swore it was supposed to be all poly with a thin metallic coating but I'm sure it was aluminum based.( I only order .008 abd.015 flakes from him because of colors I can't get anywhere else. (lt. blue, lt copper, lime, rem. steel)) If you immerse and stir in the flakes in completely, once the plastic is melted, there should be no arching. Flakes exposed near the rim of the container may arc just like aluminum that's too close to the wall. Flakes that are immersed aren't affected. ( You can use aluminum in a microwave to retard the cooking of one end of a piece of meat that's very thick, as long as it's well of bottom and away from the edges.)

earthworm77 Posted January 20, 2005 Report Share Posted January 20, 2005 I avoid this by melting the plastic first then mixing in the flake when it is ready to pour. This prevents arcing and discoloring if the flake happens to melt of give off pigment when heated to super high temps. I'm usually melting a pint at a time.

bass4cache Posted January 20, 2005 Author Report Share Posted January 20, 2005 It seems to be the silver. That stuff will start on fire if you dont mix it in. Ive added later in the heating process and its just fine. Just dont leave it sittin on the top not mixed in. Thanks for all the help Quote Link to comment Share on other sites More sharing options...
dtrs5kprs Posted January 23, 2005 Report Share Posted January 23, 2005 The large blue and green from LC will also go poof if you are not careful. Quote Link to comment Share on other sites More sharing options...
