Filling the Molds
 
Consult the table below to find the fill weight for the mold cavity you wish to fill. Measure out half the fill weight of medium Clear glass and evenly distribute it in the bottom of the cavity. Repeat this until all the cavities contain a layer of frit. Using a small spoon, evenly distribute half a gram of fine Clear over the Medium Clear frit in the cavity. This creates level working surface on which to place the murine.
 
Place the murrini on top of the frit layer in a pleasing pattern. We like using small tweezers. Finally, "stabilize" the murrini by evenly distributing another half gram of fine Clear frit in each cavity. The murrini should not be covered, but sticking up out of the frit. Carefully move the mold to your kiln. Fire according to the Firing Schedule below.
