I will try to answer what I can for you.... first off, I use a votive/pillar blend, and have not used straight parafin, BUT, it stands to reason that you should be able to use it, with some additives. I am sure others will pitch in and tell you for sure. Generally, votives will completely burn down, and its best to put them in a tight fitting container to burn them. It will also depend on what type and size of wick you use, as to how fast it will burn..... just wanted to my 2 cents worth in..... HTH
