Firstly, seeing Cyclo's post gave me a bit more confidence to post about my own wax making adventures I recently started on and second this thread is in no way meant to steal your thunder Cyclo...just thought I'd share my experiences as well
I too found lots of useful information both in Ben's Rubbish Boys thread over on DW as well as from Dom himself. I only cooked up my 1st batch last night after trying to find many of the ingredients...some of them are hard to come by in small quantities over here (> 25kg) and some of them are still on their way. Regardless of some of the missing ingredients, I really wanted to get started so I began with the recipies I had ingredients for.
First up some equipment I procured from the local supermarket. Didn't want to have issues with the wife if I happened to destroy her cookware and kitchen utensils
Trays for the samples
And some measuring cups
Other equipment used not shown is a kitchen scale, some glasses, pots and an electric frying pan.
Next up the ingredients, in no particular order
Bees wax
Montan wax
Candelilla wax
The infamous carnauba wax
And finally Coconut Oil and Paraffin
Ingredients I am still waiting for include some other bees wax, orange oil or limonene I think it is also known as.
With the ingredients out of the way my next mission was trying to find out how best to cook this stuff. Thankfully I had Dom and a few other guys share some tips and safety precautions with me so as to not burn down the house in the process.
From what I have found there is literally so many aspects involved in order to control the final outcome of the finished product. Cooking times, cooling times, ingredients and ratios, quality of the ingredients, order of ingredients, etc, it is no wonder most of this stuff is made in a lab and whilst not strictly high tech it is no wonder there is only so far a person can go at home over the stove. That being said however I don't mean to take anything away from the guys who have successfully made homebrewed waxes, with enough time, patience and determination anything is indeed possible.
Right, on to the actual cooking bit...From my initial research it seemed that the way to cook this was in a glass jar in a pot of boiling water on the stove so thats where I started. Whilst this method worked it was taking forever, I think I may have used to small a glass (a larger glass would have maximized the surface area lower down closer to the heat and possibly sped things up) or too small a pot of water.
Before getting on to how I made the other 2 of the 3 initial samples I want to share one other aspect that tickled my curiosity. From reading various bits and pieces all over the general concensus was to let the finished mixture cool on it own. Ben's original thread on DW pointed out that sometimes the waxes were crystally (don't think thats a word but anyways) so I wondered if cooling them gradually as opposed to tossing them out into cold pans might make a small difference.
With that in mind while I was preparing the first one on the stove I put the tray into the electric frying pan with some water to get that up to temperature for pouring the waxes into once melted on the stove. Needless to say I think the heat of the steel tray in the boiling water was ideal and after pouring the 1st finished wax into the tray we decided to make all of the others directly in the tray as opposed to in the pot on the stove. This seemed to work alot better and also avoided the transfer process which I was concerned about (hot wax and soft skin don't mix

)
So onto the actual samples that were made. 3 Mixes were made varying only 1 ingredient at a time to see what effect they had on the finished product.
Mix 4 was as follows :
30g Carnauba wax
10g Bees wax
30g Coconut oil
30ml paraffin
Mix 2 was as follows :
30g Carnauba wax
10g Candellila wax
30g Coconut oil
30ml paraffin
And the final mix
30g Carnauba wax
10g Montan wax
30g Coconut oil
30ml paraffin
The really interesting part after all of this is how carnauba percentages are calculated in the real world. If we took the % carnauba by volume of the actual waxes in the product then these were all 75% carnauba by volume. If we took the % of volume excluding the solvent carrier it would be 43% carnauba by volume and finally if we took the % of total volume then they are roughly 30% carnauba by volume. Now I am no scientist but these 3 samples are all pretty hard which leads me to believe I either need to add more of the carrier oils/solvents or less carnuaba to make them softer. I think this possibly highlights and sheds light on Dom's initial claims in the Rubbish Boy thread that carnauba percentages are misleading, confusing and maybe all together bogus. Now I am not saying it can't be done, rather that in future I will not look at carnauba percentages in the same way. With that out of the way on to the actual samples again.
All of the above mixes seem slightly too hard although they do melt quite nicely (except for the montan mix) when rubbed between your fingers, spread quite easily and go a long way and also buff off nicely. Interestingly as well they don't seem to be so crystally as I imagined, maybe a result of the gradual cooling process or maybe simply the way it is. As a result of the paraffin none of them smell too fantastic but that will hopefully change when some of the other ingredients arrive. As far as testing goes I stole a page out of Ben from Rubbish Boys book so to speak and used cd's. The initial testing on the cd's didn't really prove very much, all 3 seemed very similar in apperance to a control cd with no wax as well as one coated with a layer of CG's XXX paste wax. Water beading and sheeting seemed fairly consistent between all 5 as well so I don't think this is the best method of testing the products at the moment.
Thats basically it for the moment, I will post some more pics and experiences later when I have recieved the other ingredients and made another batch. Overall this has been a really fun experiment and I have a new found respect for the guys and gals cooking these waxes up in a lab someplace
Big thanks to Ben for his thread on DW and Dom in particular for sharing some of his knowledge on the subject with me
