Torch Differences.
Watch these to help you if you don't have the butane torch.
The new Argentium .940 seems to like the lower heat and less oxygen of the single canister torch (no oxygen), resulting in a smoother fused surface. This does not apply to this highly textured surface but may with other projects.
I highly recommend practicing fusing on smaller scrap pieces like these. The new Argentium .940 looks a little different at fusing temps than the .935 that these recordings were made with. The difference is the .940 doesn't get as "wet" looking before fusing. The "fusing" window is a bit shorter. (Happens quicker). There is no substitution for practice.
