Hi, I would like to share my homemade acrylic log soap molds :D :p Acrylic molds are best for those who skip gel phase :)

You did a great job! I took a class many years ago to learn how to work with plastics and I don't think I could make them that nice!

Have you used them many times? I know poly carbonates will hold up to lye for a while but have they done well long term?

Thanks! I actually use Poly(methyl methacrylate) (PMMA) also known as acrylic which is cheaper and easier to cut than polycarbonates.

I searched Google and found the following information:

Acrylic can hold lye (Sodium Hydroxide 60%) for 30 days of constant exposure with no damage. Plastic may even tolerate lye for years, conditions (122 deg F) at 50 deg C according to this website:

also try to search google for "acrylic chemical resistance" for more info.

With personal experience with a few months of using it (gel or not to gel), I didn't have problems with the acrylic, it is pretty much stable. :)

Wow! I like them!... Is it easy to release the soap?

Thanks! yup, they are easy to release! All I do is put the mold upside down so that the excess oil would move throughout the soap. After 5 or so minutes I push it from top to bottom. I believe this technique would work for ALL type of log molds.

By "excess oil" do you mean what you might smear inside the mold to help the soap to release? And, where would be a source for purchasing the acrylic?
 
Thank you guys for all the compliments!

How hard are they to make?

Working with acrylic 1/8 inch thick is easy with a plastic cutter. Any thicker is really hard to cut.

They look great. I love the one with the cutting guide.
What do you mean by allowing the excess oil to move through the soap?

It probably depends on the recipe. It is not something I smear on the mold. The "excess oil" comes from the soap itself. It is the oily substance that coats your soap when you release it from your mold, usually sets at the bottom.

I live in the Philippines :p

c0ntrite, how do you glue your pieces together?

those are the neatest, most ingenious molds!!

What sort of glue do you use to hold it all together?

I use a solution specifically made for acrylics. Watch the video below from tapplastics.
