Hello, I did a full fuse with 2 layers Spectrum glass. After that full fuse I did a tack fuse with 2 layers on the first glass. Temp. 750 degrees Celsius. But the 2 layers had spread out, it look like a full fuse. Do you have to use a lower temp. by 4 layers ? Jan de Jong

No, posting here is fine.

How long did you hold at 750?

Are you sure your thermocouple is reading correctly?
Whatever the case, maybe hit your target temp for only 5 minutes?
