Melting sulfur in mineral oil
Just as the title says can you use a high temperatire solvent to melt sulfur and have it crystalize

As long as it doesn't dissolve or react with the solvent I don't see why not. Another route is to dissolve it in hot toluene and grow crystals by slow
cooling of the liquid.

Sulfur reacts with mineral oil at high temperatures to generate alkenes and hydrogen sulfide. Stick with toluene or xylene for recrystallisation

What's considered a high temperature, though? Sulfur melts at only 115 C.

I have achieved this in rape seed oil when experimenting with sulphurised oils for lubrication. At lower temperatures (probably right around the
melting point) sulfur simply dissolved, precipitating out again upon cooling with little discoloration of the oil. At slightly increased time and
temperatures it reacts to form a dark oil from no precipitation occurs. There could be an upper limit to how much sulfur that can react, but I never
went past 10%.
We're not banging rocks together here. We know how to put a man back together.

I did this a while back, didn't seem to generate any H2S for some reason. A tiny percent of the sulfur dissolved though and formed some nice crystals.

Here's a crystallization from Xylenes.
I will never tire of watching these form.
