If you have ever wanted a special shape that you just do not seem to be able to find on the Mold Slumping sites, create your own out of MM6. (yes you can create out of clay too, but I like to use MM6. These molds, if handled carefully will last for a very long time , and do not shrink or thermal shock (BUT while creating them , you have to take pre-cautions so the large flat areas do not curl.) (Hence creating more problems for you. ) When Mold Mix 6 dries it wants to curl up at the large flat edges. I try to weigh it down on the outer edges while it dries. I use a hairdryer in between painted on layers of the mold material. This will help when finished the painting process to weigh down outer edge to stop curling . BUT a better way is to make a side on the original shape design you carved out of clay or which ever you chose to use as the original design. This helps MM6 to NOT curl on you. (like in Picture number PHP9JPiHVAM. )I usually will carve my shape out of clay, make a #1 pottery Plaster mold over the clay giving me the negative mold, then paint on Wax onto the #1 Pottery Plaster Mold. I can make as many waxs as necessary for slumping molds .
When painting the MM6 onto this wax, make sure to go thin and brush on very evenly . Dry the first layer with a cold fan, then apply another layer when it feels tacky or not cold to the touch. Dry this so that it is NOT cold to the touch as well, and build up layers until 1/8th to 1/4 thick. Weigh down at final stage when done building up layers. These molds should last for a very long time if taken care of. This technique makes EXCELLENT Drop Molds tooo!

Because the mold mix 6 does not shrink, this is necessary and also gives a nice soft curve while the glass drops down.
