Several weeks ago, I got ten pieces silicone mold for chocolates. At first, I couldn’t believed how cheap they were. The same amount could only buy three pieces polycarbonates.
These set has different shape from before. Each mold consist of 15 round tablet like cavities. I have been using them to make local unflavored chocolate called “tablea”.
What could I say about silicone molds? Keep reading!
More efficient cooling. Its make is relatively thinner than of polycarbonate. Cold air penetrates faster from the underneath.
Easy demolding. Silicone is soft and smooth. Hardened chocolate separates easily from surface. Even if it stuck through unwanted phenomenon (seizing). Back of individual cavity can be pushed with ease to expel the chocolate out. Polycarbonate never offer this feature. Your head will surely ache when batches gone out of control. Taking them out is very difficult. Bars will break and leave undesirable marks. Molds should be re-clean thoroughly before proceeding. Plus the bad looking batches that should be remelted and re-tempered.
Hard to handle. I can hold the poly with one hand. I can hold the silicone with one hand too but the freshly poured chocolate will drip off. It is a mess. Using two hands never did the trick. The center is sagging down allowing some liquid to fall. Pulling both ends straighten if up but causes the cavities to deform.
I provided a sturdy wire mesh to solve this handling problem.
Another problem attributed to its soft nature. When pouring chocolate to molds, wiping off excess should be done carefully to prevent denting and spillage. Maybe it is not a problem for hobby purposes but surely is for businessman. It kinda slow down the process. This also makes it unfit for semi-automated production line.
Post production clean-up. With polycarbonate, debris could be wiped easily with soft cloth, quick dip in a warm soapy water and final rinsing. Silicone got a low grade in first cleaning step. I have to scrub each mold with bare hands while simultaneously dipping it in warm soapy water.
