I bought a bar of bronze recently. I don‘t want to cut it as that would would waste bronze and be some what time-consuming. can I fuller it?
If you are really careful that you don't melt it instead it could work. The problem could be that bronze melts at a much lower temperature (about 1700-1800F) than steel (about $2400). So if you don't keep an careful eye on it, it might melt and you'd end up with a puddle instead, but in principle it should work. I think before they came up with iron people did use blacksmithing techniques on bronze and copper. But if your bar is thick it might be too hard to get the temperature even enough over the whole bar, so that the inside is hot enough without the outside melting. Bronze won't give you the warning of sparking before it melts and it melts while it looks red, so less variation of color to tell you where it is at. Depending on what saw you have, sawing is easier than drawing it out. Depends also how thick your bar is.
Bronze can be remelted (the scrap) and that will probably be less time consuming than hammering. Bronze is also less ductile than brass (both depending on the percent copper and the other elements) and may be brittle and break when you hammer, like cast iron. Steel has a very large working range and I think you will find bronze very short.
