According to BDOCodex, Rosar mainhand weaponry should return the following items when processed using Heating:
5-5x Melted Iron Shard
1-1x Trace of Memory
1-1x Pure Titanium Crystal
However, this is incorrect.
After Heating a couple hundred of them, this is what the average results window looks like:


The results should therefore be changed into:
1-4x Trace of Memory
0-1x Pure Titanium Crystal
The Melted Iron Shard seems to be exclusively from Offhands, and it's not a guaranteed five from what I've seen.
Thank you for your time!
