DON'T hack into your master silicon guy!!!!

1. Silicon is really hard to work, being essentially rubbery glass.

2. Any cuts you make will be nearly imposible to smoothe out.

3. It's really pretty and would be a shame to hack into.

Having said that, I've never tried to work silicon. Just never occured to me as a good idea. I'd try sanding and working the conical mold you made first just to see how the stuff responds to tools.

I'd make another stone mold instead. See if you can't re-route your part line to accomodate the lips, it might just be possible, plus it's nice to have practice.

Cheekytiki is right about the bottom bit. All of our mugs save primo have a bottom portion on the mold. It's really easy, just do your clay-up with the mug touching the bottom of the box. Proceed as normal, then turn the thing upside down, build walls for the bottom piece and pour away. Of course putting keys wherever necessary.

Hope it's all working out. Best of luck.
