What's a good way to decide if I have an Oil in Water or a Water in Oil emulsion? My emulsion looks like a uniform opaque liquid so it is hard to decide visibly.

 

Most emulsion breaking books seem to rely on this characteristic.  The emulsion has an oil phase, water and about 3% of suspended solids. My goal is to find a way to break it chemically. All the coagulants / flocculants / demulsifiers I've tried so far don't seem to work. They've been mostly polyacrylamides and polyDADMAC  etc.  high MW synthetic compounds at ppm levels.
