I'm looking for a way to make paraffin wax have a higher melting temperature than it does, but without effecting how it drips. (this is for an artwork, so if it does then it spoils the look) Also without effecting the opacity too much. The melting temperature range I'm looking for is 100-110C. Are there any chemicals I can mix into liquid paraffin to achieve these properties? Ideally what I'm looking for would be chemicals that don't cost very much and won't make the wax toxic, or have such a low toxicity that it doesn't really matter if I happen to breath some of it when I'm making it.
