4metals said:Another thing you should be careful of is the actual size of the bar which has cooled in the crucible. If it is a bilge crucible, forget it, it isn't coming out, but it will not be easy removing any melt cooled in a crucible from the crucible without crucible damage.
But after you have the bar. I hesitate to call it a bar, the blob is better, the next step in your processing will involve it being cast into anodes or other shapes useful to further process.
If you have issues with pouring into a mold, why not pour shot? Shot can be remelted into bars, processed in acid, processed in silver cells, or sold as is. This thread may give you some suggestions.

Shot's sell if people trust their refiner. Many refiners worldwide bottle up shot of gold and silver in one kilogram bottles to sell. They particularly sell to jewelers and manufacturers who create their own alloy.
