What filler do I add to simulate the density of wood?

Our Ure-Fil 5 is a popular choice for this.

I want to make trumpet mouth pieces that are softer than the actual brass ones. Will this work for my intention? Will this include all that I need?

You could make a mouth piece with it, but whether the chemicals are safe for humans is a different story. The people at Smooth-on are available everyday to give information on the safety and life of their products. Go to the web site and give them a call. There is much to be learned, and they have the place to do it.

i wouldn't eat it....or anything out of it....

i want to make glow in the dark jewellery with glow worm powder. i want solid form not the rubber type. so which is best for me smooth cast 325 or 300

both products cure into solid form. 300 cures white, 325 cures clear. keep in mind that glow worm powder makes both cloudy. and if you use pigment, 300 is more pastel.
