The T divider for the TS silicone mold allows you to use your TS silicone mold to make several smaller batches at the same time. It can be used to make 2 six bar loaves or 3 one pound/four bar loaves at the same time. It is also helpful if you soap with full water and experience bowing in the center. The TS divider will hold your mold in place and eliminate bowing. The kit comes with two T dividers. The T divider is made in the USA specifically for the Original TS silicone mold.
