"Heat cave" is a great term. I like it better than "oven". And, yes, a "heat cave" makes all the difference when soldering a large piece of standard Sterling. Argentium Sterling (AS) is a bit more forgiving on large or long pieces, so I've been using that alloy for those pieces.
Am trying to compare AS with Continuum and Sterlium so far as ease of soldering large pieces. Any input from others who use these alloys??
