What kind of alcohol, and where do I get it. For a bunson burner, it says "denatured alcohol". Is that isopropyl, ethyl or other?

Denatured alcohol is also reffered to as "Wood Alcohol".

Typically when one talks about "bunsen burners" they are burners that run on gas like propane or butane, and not alcohol. At least I never heard of that.
I have a small alcohol burner lamp (not gas) where, I use denatured ethanol for my burner and it works fine. At least in sweden "denatured" means it has additions so you can drink it, or easily distill it to get something drinkable. I by ethanol cheap for my burner, but it is "denatured" and if you try to drink it you'll have it come back up. Denatured ethanol in sweden is a means from allowing sales of cheap ethanol (ie. alcohol tax doesn' apply). If it wasn't denatured potheads would buy it for drinking instead of for their burners.
I use my burner mostly for glasswork, melting glass pipes etc. It works pretty well.
Methanol would work fine too, but it's more toxic to ingest, but also in Sweden more expensive and hard to get.
Using isopropyl alcohol in a burner would probably be quite dangerous as it's too volatile.

in the US, "denatured" means the alcohol has stuff added to it so it's NOT drinkable.
"Denatured Alcohol is ethyl alcohol, or ethanol, containing traces of benzene. While ethenol, in it's natural form, is a source of combustible fuel, it contains trace amounts of water making it less efficient for burning than in it's denatured form. Introducing Benzene during the distillation process drives out the water contained in ethanol creating a very pure and potent fuel source - denatured alcohol.
NOTE: Ethanol is the alcohol consumed in alcoholic beverages. However, once denatured, ethanol becomes toxic and can cause blindness or death if consumed."
Other sources say that denatured alcohol is ethyl alcohol with a small precentage of wood alcohol added.
Not matter how it's denatured, you don't want to ingest it!!!
as PaulK says, wood alcohol or denatured ethyl alcohol is available any any decent hardware store
