Tm Customs Posted June 24, 2004 Report Share Posted June 24, 2004 Most of the time I melt it in the microwave then keep it warm on a burner, but Chris tells me that he's had them explode. Personally I have not had any problems yet but try this at your own risk. Tm Quote Link to comment Share on other sites More sharing options...
Senkosam Posted June 24, 2004 Report Share Posted June 24, 2004 Most Pyrex instructions caution against using any glass over direct heat. Explosions can occur! Metal measuring cups are your best option for burners, but care must be taken not to sear or overheat. Heat stabilizer is almost a must.

alsworms Posted June 24, 2004 Report Share Posted June 24, 2004 If there is any moisture at all in the plastic, it can be very dangerous. Some of you guys who live in high humidity areas should never try it. I shattered a pyrex cup and I live in a very dry part of CA. Moisture was the cause, not high heat. Most plastisols will have at least some moisture in them, even with proper sealants. Typically, there's no way to avoid that as moisture will seep in during the transfer process. It's really a question of......why risk it when a microwave is safe and will cook your plastic much faster? Plus they are really cheap now. I saw one at Walmart for 28 bucks the other day. You can't get a pair of burners for that. Quote Link to comment Share on other sites More sharing options...
vishezfish Posted June 24, 2004 Author Report Share Posted June 24, 2004 I been using the microwave but I got a 2 burner set as a gift and thought about trying it!! U guys are wizards, I read all the posts and I am amazed at all the info and cool lures you all make! Soon, after I get better I will post some pics of my stuff and see what you guys think!! I was going to buy the calhoun plastic from delw, but man the mailing price was crazy!! So I went with Zeiners, just to see how it works, I'd like to get calhoun, but the mailing priced was almost as much as the plastic... holy^&&*!!!

WallsOut Posted June 25, 2004 Report Share Posted June 25, 2004 Talk to April at Del's and ask her about getting it shipped Fedex. It's only $15.24 to ship 5 gallons. I know with the regular shipping it isn't that much more to get MF plastic since they only charge 10 to ship 5 gallons. Eric Quote Link to comment Share on other sites More sharing options...
nova Posted June 25, 2004 Report Share Posted June 25, 2004 I had a pyrex explode on the burner. What a mess; not to mention it darn stopped my heart. It really gets your attention. Don't put it on the burner. Quote Link to comment Share on other sites More sharing options...
WallsOut Posted June 25, 2004 Report Share Posted June 25, 2004 What about putting it on a hot plate like the kinds that keep coffee hot. Aren't the coffe pots made of glass? Anybody tried this? Eric Quote Link to comment Share on other sites More sharing options...
DeVeryTY Posted July 1, 2004 Report Share Posted July 1, 2004 :!: As an art glass maker i'd advise against using a flame on a Pyrex (Borosilicate) glass container. Glass expands and conducts heat at different rates, meaning the glass is hotter at where the flame is touching than at where it's not. It can and does shatter, "explode" with some violence when heated unevenly. There are Pyrex COOKING containers on the market which may be able to used in the way you want to, you'd be advised to read the instructions very carefully before doing so though.
