Ok so I have been up and running in my shop for 3 months now. I had to admit that the spectrum nuggets are working out just fine. They are stiffer than SP, but much less stiff than c4. If SP was a 10 on the workability scale and Bottle glass was a 1.
Sp -10 - Longest working time, softer the longest. Everyone knows how to do this.
FHC- 8.5 - Softer than spectrum, Quick transition from stiff enough to work to locked up. Bubble fine out at 1950 no need to squeeze over a 24 hour period.
Spectrum - 8 - Not as soft as FHC, but a longer working zone. Load it at 2150, cook overnight at 2150, ramp down to 2100 can blow. Fines will be gone in my wire melter. Never got them to fine out over night any other way.
C4 - 5 - Stiffer than everything above, locks up pretty quick. 2125, cook over night, still had fines but they where so small it did not matter. Where gone the next day.
Bottle Glass - 1 - Well you know.
Just my personal observations above take with a grain of salt I am still pretty new to this.
Now onto the Glory hole question.
I would like to build a small glory for just paperweights, goblets, small pumpkins, shells, etc..etc.. All small stuff. I don't need the 16 glory for most of the stuff I do at the home shop and with the price of gas I was looking to shave some of that outgoing money down.
I was thinking about just making it square, with 1 inch fiber, and 1 inch board on the outside. IFB cut in 1/2 on the inside. Hold it in with what amounts to thick chicken wire and coat it with heat resistant paint. Build a retension ring out of IFB and leave it open...no doors.
5 inch oriface, 7 inch inside, propane fired with forced air.
#1. Does this sound like a good plan.
#2. What type of burner should I use for this.
#3. Any other advice very welcome.
