first time casting- I am casting in a pyramid mold, about 3" high and 3" wide at base. Using system 96. Will use bits and pieces of glass. They do not have a schedule for a deep mold. I assume I will get lots of bubbles, and run the risk of breakage if it is not annealed properly.

Have anyone cast in this type of mold with 96, and can offer a schedule?
Thanks!

I'm curious too, I unpacked my Slympys Pyramid mold last night and gave it a spray of MR-97. It's a lot bigger than I thought it would be.

I used primo primer on mine. did I need to use boron?

(FYI- I have a smaller pyramid as well, brand new , if you want to buy it.)

any schedules out there?

I've cast several... the size and number of your bubbles will change with the size of glass chunks you use... bigger chunks less bubbles.
Standard kilnwash coating works fine.

Don, do you have a schedule? Do you use 90 or 96?
thanks

Here is the bullseye schedule. I found this by googling "pyramid mold firing schedule"
