ROOM SCHEDULE (70-74° F) (43%)15-1/2 minutes Total Time
Start 15:30
1. (mixing) Start at lowest speed to mix ingredients, slowly (over the course of 1 minute) increase to speed 12
AT 14:30
2. (whipping) FROTH at speed 12 for 5 minutes
At 9:30
3.(medium refine) speed 4 for 4 minutes
At 5:30
4.(ultra-refining) speed 2 for 4 minutes adding 2 grams ammonia
At 1:30
5. Add GELLING AGENT, 15sec. then color 15sec
At 1:00
6. Turn bowl backwards by hand to mix gel for 30 sec , then
Let mixer run until 15-1/2 minutes have elapsed. OFF
Quick ,I poured into the mold , Put the die mold in place .
Foam gelled in 20 sec.
Cooked 11 hours at 125 deg.
2in.around the edge of the mask Did not cure.Because that is the closest to the walls of the oven.
Some bubbles,I think because it started to gel some as it pour into mold.

It came great, It was short in 1 place near the top right vent ,This spot would be cover with hair anyway. 4or 5 little bubbles ,But no away like the 1st one.The whole thing cure ,11hours and the 10th turn on the heat up to 140 ,So 10 hours at 126 to 129.
I think I will keep the batch size and make sure I scrape the bowl clean,Or injected it.
The oven worked Great. Oven cost $150.00 to make.
So, Now what ,I will get all of the mechs done and set eyes place.The eyes are in place but not just right. A couple mm forward or back.And then measure lip springs.
So ,Getting the whole skull thing working and talking ,ears casted too. And run another skin.
I love MonsterMakers Foam.
