Love Your Suds small batch, artisan, handmade soaps Blog Vancouver BC Canada
There's beauty to be found in imperfections. I have always liked the idea of embracing things that are perceived as being imperfect and transforming them into design elements. This concept is perfectly captured by the Japanese philosophy of wabi-sabi, which encourages us to see the beauty in the flawed or imperfect. I also find that when I give myself permission to make mistakes I become more relaxed and often find greater enjoyment in the creative process. Any unplanned deviations along the way can then become opportunities to discover new and exciting techniques. This is one of the things I find most rewarding about soap making; the sense of being on a journey and making new discoveries.
For the month of February 2019, Soap Challenge Club members were encouraged to explore glycerine rivers as a design element in their soap making. Glycerine rivers is the collective name given to the crackled, marbled or mottled effect that sometimes shows up in cold process soap making. The effect is more likely to occur when higher temperatures are reached during the saponification process. Once the rivers have formed they are more translucent and often darker than the rest of the soap that surrounds them. They are purely cosmetic and have no adverse affects on the soap itself. Almost all soap makers aim to avoid them though as they can end up distorting carefully planned designs and swirls.
Our guest teacher this month was Clara Lindberg of Auntie Clara’s Handcrafted Cosmetics – a pioneer in the soap making community and an artist to whom I have looked up to since before I began making soap. She is innovative, thoughtful and technical in her creative process, and incredibly giving of her findings which she shares through her blog posts. She is also not one to shy away from glycerine rivers and has explored them as a design element in her creations.
This was not my first time embracing rivers either. Here’s a capture of Marble Rose artisan soap, an otherwise vegan soap that I made late last year to which I added SPORT COLLAGEN – an addition to my wellness regiment under the supervision of my naturopath, Dr Aubrey Shannon. I have been using it for a few months now and my nails have never been better. My hair and skin have improved too. With this in mind I figured it might work well as an ingredient in my soap making. Testing is still underway and I am hearing great things so far from family and friends. I am enjoying it too, particularly because it is scented with rose absolute.
Having explored the marble-look already in my soap making I wanted to try something new for the challenge. I also wanted to push myself further to see if I could capture rivers in well defined sections of my soap design. It got me thinking about anything in nature that might lend itself to a crackled, marbled texture. An iceberg seemed like a great subject to explore.
For the first batch I used a vegan recipe packed with shea, cocoa and mango butters, which was scented with a blend of eucalyptus, peppermint and rosemary essential oils from Hughes & Company. The water content was increased by 30% in the sections where I wanted the rivers to appear. Glycerine was added to these sections too. Some soap makers believe that adding glycerine may increase the chances of glycerine rivers appearing. You must be mindful of how much glycerine you add though as it can prevent the soap from hardening when used in higher quantities. For colourants I went with indigo, activated charcoal, caribbean blue mica from Bramble Berry, titanium dioxide and a dusting of silver mica along the water line to give it some shimmer.
Once the final layer of soap was poured it was into the oven for 30 minutes on the lowest setting (70 deg celsius / 158 degrees Fahrenheit). The oven was then switched off and the soap left in the oven undisturbed until the following morning. I used a my silicone lined 2.5 pound tall skinny premium soap mold from Nurture Soap. A towel was also placed over the acrylic lid for some added insulation. The next morning I removed the soap mold from the oven and left it on the kitchen counter while I went to work for the day. Unmolding and slicing happened later that evening – approximately 22 hours after the soap went in the oven. Although I was happy with the design, only a few very faint lines or wobbles were apparent on very close inspection. I wanted the glycernine rivers to really stand out though, so I decided to try again.
For the second batch I simply increased the water by 30% and did not add any glycerine. Everything else remained exactly the same except that I added a touch more indigo to the swirls within the submerged part of the iceberg. This time the rivers were clear and well defined, as were the halos which I really like too. They add some extra definition the “rivered” parts of the soap – the top and submerged sections of the iceberg.
Although more testing is required to drawn any definitive conclusions, the results lend themselves to suggest that adding glycerine may in fact discourage the formation of glycerine rivers rather than encourage them. This is something I am curious to understand further as I learn more about the science of soap making. I will be sure to provide updates.
I really enjoyed this challenge. Thanks to Amy for hosting and guiding us through the process. Many thanks to Clara as well for sharing her tips and techniques, and for inspiring us to see the beauty in glycerine rivers. Best of luck to the club members who participated too. I am looking forward to seeing your creations and hearing about your experiences.
