[QUOTE="capickettcdt, post: 30503, member: 3074"] NO... You (Rob) use a slightly different set than we have been using here and they are working...I wouldn't change a thing. I've had folks with longer press times have reaction layers that were unacceptable so we ratcheted back and got good results. We have been suggesting that the users use all of the Ivoclar numbers for both the 100 and the 200 gram rings and then use press times based on the weight of the wax pattern and sprue (just like the old empress days prior to EP5&6). That means that your press time could be anywhere from 2 minutes to 5 minutes. We haven't published anything really....because that buys into the IVOCLAR idea that the furnace controlls the glass...this is not true. The glass and the manufacturer of the glass determine how it will be fired (ask any manufacturer except Ivoclar) not the furnace. It heats up at a specific rate...holds vac...and presses or releases. Glass manufacturer...tell me what you need for your glass and I'll program the furnace to do it....unless you want to leave out an important piece and try to turn the industry on its ear so you can sell furnaces. (I've spent too much of my day answering Ivoclar "won't tell me" or "they just want to sell me a furnace" comments and questions. I always thought that the money was in the TP not the TP holder!! Well enough said. There are folks who are very successful with our furnace (present company included) and very successful with the EP's. The dialing in is always a good idea. [/QUOTE]
