Thanks Paul

No, most molds are built for oils used only. I build all my TOG Molds that way. My TOG Mini 1 Pound Test Mold http://www.etsy.com/view_listing.php?li ... d=11100771 uses 1 pound of oils, but the log will produce 5, one inch bars that will weigh a full 4 ounces each after cure, or 20 ounces. The lye, liquids, fragrance or essential oils all add extra weight, but most of the water will eventually evaporate.

Here is an example.

My mold volume is 0.09m x 0.06m x .5m = 0.0027m3

If you equate this to water weight, it would mean 2.7kg or 2700g

So does this mean that I need a total of 2700g of oil for my recipe? or does the 2700g include the water(200g) + Lye (100g) so the total oils are 2400g.

Hope this makes sense and I apologise for it being in metric.

You forgot to multiply by .4 The correct amount of oils only to be used is .00108m3 or 1.08 kg or 1080g of oils for your mold. For us US folks, the final number would be 38.16 ounces. :wink:

Paul :wink:

If you have a base recipe that you use consistantly, you could tweek the formula for your own use by melting your weighed oils and recording their volume in fluid ounces. Mix your lye solution and record its volume in fluid oz as well. Add together for total volume in fluid ounces, then multiply by .554 to get volume in cubic inches. Then take the original weight in oz. of your oils and divide them by the volume in cubic inches. Use the resulting fraction instead of 0.4 in the mold formula.

Heh! 8)

if you are going to base your calculation on water volume/weight and you have a simple mould size, there is no need to fill it. Just use the calculation like I did above this was based on water which has an SG of 1.

Soapmaker man,

I was always under the assumption that the 0.4 should only be used if you are calculating in INCHES. Can you clarify please?
