Is it possible to have a liquid plasma? Plasmas are generally thought of an ionized gases, which are conductive and can respond to electric and magnetic fields. However, I was just wondering if it is possible (in theory or in practice) to have a 'liquid' plasma? Presumably, it should be possible to ionize a liquid?
If not, then why is this not possible?
Edit:
One of the comments suggests that the interior of the sun may be a possible candidate, due to the high density. However, I am wondering, on a more basic level, could I take some sort of liquid at room temperature and ionize it in a lab until it started to behave like a plasma? Is it possible to 'bulk ionize' a liquid to that extent?
 A: It is not possible to bulk ionize some liquid substance to produce a plasma at ambient pressure. The temperatures required to produce the plasma are greater than the vaporization temperatures of anything we have on hand- so, the stuff vaporizes before it ionizes. 
At the center of the sun, the density of the plasma is of order ~150 grams/cc which is 150 x the density of water, but since there is nothing you could possibly make a pipe or bucket out of that could withstand the temperature there, the "liquidness" of that substance can only be inferred by studying the transmission of pressure waves around the insides of the sun. This is called helioseismology and the results from that field indicate that the sun's core behaves like an ideal gas under tremendous pressure. 
A: Depends on what you mean by 'liquid'
Liquids, by definition are a different state of matter than plasmas.
If you mean a high density plasma, I see no reason why a plasma can't have a density on the order of 1 g/cc.
If you mean a high conductivity liquid, yes, these exists.
There are also ionic liquids which are another name for molten salts.
A: If you strip electrons from a liquid and then mix them with the cations they will recombine but it is possible to prevent it by heating it to high temperatures, enough to convert the liquid into a gas.
Ionic liquids are similar to plasmas because they are composed by cations but they do not have electrons, they have anions. 
every ionic compound like the NaCl will become a a ionic liquid when melted, ionic liquids conduct elecricity and have electric field screening like plasmas
