I tried ice-cube moulds, I tried silicon baking moulds, I had a wooden mould made by a carpenter, then I struck gold at IKEA one day with my Molger Moulds. As I found them in the bathroom section, they are probably meant for organization and storage in the bathroom but they are AWESOME soap moulds and very economical. The three moulds together in this picture cost between 7 and 8€ total.
The smallest of the moulds, an excellent experimental batch mould, makes three soaps 81mm across, between 50mm and 60mm height (depending how you want them) and the soaps in this picture are about 26mm thick, but you could make thinner or thicker soaps. None of mine are the same as I hand cut them. The soap you see in this picture is a variation of my beer, egg & honey shampoo bar. This one has goat milk, egg & honey and something weird happened in the middle, darker and speckled, as you can see in the photo. If you have any ideas on how to correct that, suggestions welcome!
The middle mould makes about 6 (and a small slice) soaps but again, it all depends on how thick you want them.
The longest mould makes between 9 and 11 soaps.
My only issue... I do love these moulds but here I go “tweaking” as my blog buddy at http://thesoapsister.blogspot.com/ calls it. In trying out other soaps, I realize I prefer smaller width soap. I am not sure I like mine 81mm across. They may just seem a bit unmanageable in the hand at first. If you look at the photo below, mine is the last one in the row.
I think my favourite width so far is the soap I got in a Soap Swap from http://cocobongsoaps.blogspot.com/ , which is 75mm across (Second one from the frount in the photo above). If mine were that width, I could cut them thicker as well, which I like. I love the look of the size of the soaps at Beguile Soaps http://beguilesoaps.blogspot.com/ and Platypus Dreams http://soapobsession.blogspot.com/. So I will most likely try to modify my Molger moulds somehow. I have been thinking of cutting a magazine down to the mould size and sticking it along the side, or I may get a carpenter to make me wooden inserts which I could just slide into any of them.
Happy soaping!!
