When my good friend told me that he wanted a rough gold bar with his young daughters name in it to hang on a chain for his wife, I have to admit I didn't know what to make of it. I'm a little more accustom to making much more polished and finished pieces. Luckily, I'm in the business of making sure my clients get what they want. He had all the gold, we just put a blow torch on it and poured a small ingot. Then a few passes through the rolling mill to flatten it out. Solder on some jump rings to hang it on a chain. Rough engraving (what he wanted) is quick and easy too. I'm rather pleased with the results, and there wasn't hours of sanding and polishing either.
