1) Line up the materials you are going to use from left to right - to the right side of the mixing pot. (or vice versa if you are left handed).
2) Keep the materials you are not using immediately, well away from the mixing area so that no cross contamination is likely to be caused.
3) Keep the formula so that you can read it clearly and have a pencil handy to make notes.
4) Select the first material and move it closer to the mixing pot.
5) Verify the name, unscrew the cap and smell the contents. Are they correct?
6) Lift the tube clear of the liquid, squeeze the rubber bulb to eject air from the tube.Dip the tube back into the liquid and release the bulb gently allowing the material to be sucked up.
7) Holding the cap and rubber bulb move the end of the tube over the mixing pot. Keep the tube upright as the drop sizes will be smaller and more consistent in size. Try not to drop the material in the centre of the mixing pot to reduce splashing. Allowing the drop to run onto a cocktail stickand drop of the end will give smaller drops.
8) MAKE SURE THAT THE END OF THE GLASS TUBE NEVER COMES INTO CONTACT WITH THE POT AND THAT SPLASHES DO NOT CONTAMINATE IT.
9) Gently squeezing the rubber bulb allow the first drop to form and wait for it to fall into the pot - first drop. Maintaining gentle pressure on the bulb allow the second , third drops, etc. to fall until the required number have been added. To add very small proportions you can upscale ie. making 1000 drops instead of 100. Alternatively use solutions by mixing 1 drop + 9 or even 99 of Zolvent before using).
10) Maintaining or slightly releasing pressure without allowing more drops to fall move the tube back to the bottle. Smell the bottle again and verify the name to make sure you have the right bottle.
11) If the bottle neck or cap thread is wet, wipe it clean with a new piece of tissue paper.
NEVER USE THE SAME PIECE OF TISSUE FOR MORE THAN ONE MATERIAL -THINK HARD BEFORE USING IT TWICE.
12) Screw the cap back in place so that it is airtight without overtightening.
13) Move the used bottle away from the mixing area to the back of the materials not yet used.
14) Place a tick against the quantity you have added - If you have added too much or adjusted the amount - write it NOW on the formula - so you can reproduce the same smell later.
15) Try to place the used bottles in order of use so that if you ever forget where you have got to then you can retrace your steps easily.
16) When all the materials have been added then then using a toothpick stir them until your are sure they are thoroughly mixed. Then stir for another 30 seconds to be sure for safety.
17) Ideally a sample you have made should be kept overnight before smelling. (I bet you don't though!) If you decide to keep this sample pour into a bottle and screw the lid on airtight and write a label.
18) On the label include: Name of the perfume/base. Code Number you have given it. (when you have made 100's how are you going to find just one sample named "Rose"?).
Who made it or batch/sample number if you really want to be professional Quantity made. The date.
