brush soap

I make brush soap it's not smelly or hard to do, if you use a hand blender.

First if your worried read the info at this site http://hometown.aol.com/oelaineo/blender.html, gives a complete description of this method worth a read.

And for those who want to use different ingredients visit this site for lye calculator ,http://www.the-sage.com/services/calculator.html, these sites give excellent information on soap making.

Linseed oil brush soap.
250 ml linseed oil ,ordinary decorators not artist quality.
94 ml water
32 grams Sodium Hydroxide,Red Devil (drain cleaner, be very careful with this)
extra oil veg/olive or liquid parafin 25 ml

Handblender, plastic bucket, container for soap/soap mould. Very important wear eye protection at all stages.

Put water into bucket and add sodium hydroxide slowly, this will heat up (heat of formation) which is an important factor, stir the solution with a wooden spoon until crystals have dissolved and solution is clear.

Add linseed oil to bucket, stir slightly with wooden spoon, with the hand blender stir until a trace is shown, 15 min appox. Trace stage looks like a thick custard.

After traceing add the extra oil which will act as an emollient, this is what is left on the bristles after washing, which helps keep brushes in good condition. Pour soap into a container, empty butter tubs will do, let the soap
cure for 3-4 weeks (this is when the ph drops to around 8 )before use, it gets better with age.

Sodium hydroxide is the most dangerous ingredient, but as it is used as drain cleaner responsible care taken will prevent injury. Many people recommend letting the sodium hydroxide solution cool before adding oil and cooking the mixture, as stated the heat of formation will provide all the heat required to cook the soap.

This is the method I use and take no responsibility for any injuries or damage.
