Solly Cholly .... that is the recommended procedure direct from Corning for
filling in large cavities. I was on a project in Austin once where the glass
company hung a 3' high x 12' long, 1" thick piece of plate glass over the
entry to the ballroom prefunction area (after I'd etched on it). The glass
was first positioned top-edge-down into a steel beam with steel plates
attached 6" tall .... the 1/2" wide cavity left betweem the front and rear
surfaces of the glass was filled, 1/2" at a time per instructions, with
silicone...and this, according to Corning, would support the entire weight
of the glass!!!!! The glass company decided to put 2 small steel supports
under the very ends ofg the glass "in case"...I agreed! The entire piece was
then flipped over and hung by the steel beam between the floor to ceiling
etched panels on either end. Technically amazing...I did my part, they did
theirs.....

fresh silicone generally won't stick to cured silicone. nothing usually
sticks to it, for that matter.

Now that they've had their fun with you, I'd say to check out Latex Mold
making material.... or such. I've made molds with it and it may be the
consistency you're looking for. Or try good old silicone in a tube, eh?
Squirt that stuff into your mold and give it a week or so to cure... or
simply build it up in 1/4" thick layers which will cure overnight, than
add
another layer. It does come in black for that traditional all stopped up
look. I only "ask outside the box" when my thinker stops thinking
outside
same. See what else YOU can come up with and let US know....;-) I'm
sure
curious... and remember, the perfect wheel ain't been invented yet!

Greetings all,

I would like to make my own rubber stoppers I have created a mold using
plaster of paris,
I have tried epoxy and fiberglass resin but these end up being to hard
does anyone know
what I can use to make softer rubber stoppers.

TIA SAL
