how to make an emulsion

think emulsions (mixture of 2 immiscible liquids) are hard to make? well think again!! haha

1) measure out the ingredients for primary emulsion, i.e. oil:water:gum in the ratio 4:2:1 if it is fixed oil, or otherwise

2) measure out other ingredients such as nice flavoured peppermint water, strawberry water, avocardo water, etc, syrup; pour nicely in cool and stylish glass measuring cylinders.

3) take a porcelain mortar and pestle (must be the big big porcelain type!!) kiss it gently.

4) wash the porcelain mortar and pestle througholy and wipe it dry, as if you were selling it as a brand new one.

5) you can put the gum (powdered acacia) inside the mortar. gently pound it with the pestle to remove lumps, like a sledgehammer. make sure everything is ground to dust (literally)

6) say your prayers, oh my god i hope this works.

7) cross yourself

8) crack your knuckles

9) inhale, exhale

10) with bated breath, seize the container which contains the oil

11) and pour it into the mortar

12) and at a speed of about 4-5 rps (revolutions per seconds around the mortar), with the pestle, triturate (grind and mix) the contents like, someone owned you money. continue for about 5 seconds.

13) hesitate, then grab the container which contains the water phase

14) and pour it over the mortar and pestle such that the water nourishes the contents

15) and MIX!!!!!!!!!!!!!!!!!!!!!! speed: 4-5 rps.

if you mix hard and fast enough you will see the oil (golden yellow) + gum (light brown) + water (colourless) turn into a white milky viscous substance that resembles something like milk/yogurt. it is very sticky and makes a "pip-piak" sound. haha....

lol after last week's and this week's prac, we have all become masters of the emulsion... my suppositories still suck though haha
