Weight vs Volume Measurements in resin/silicone castings?
What is the go-to weight "measurement" in the industry when making SFX type items? For example, if I'm going to send instructions to someone to build a widget that needs a resin mold and then silicone casting, what is the preferred measurement to use? While I'm a believer there are no stupid questions,, I feel kind of silly asking this. But you don't know what you don't know right?

i prefer to use the Volume as measurement.
Its easier to use volume because it includes the size of the surface and the hight/ strenght of the items wich will be builted.
Depending on which material is used and which density it has, the weight can spread a lot while the volume will always be the same on the same project.
I hope it helps.

In my experience, it's mostly ounces or grams if it's a really small volume and accuracy is required.
In some cases, the volume is good as you may have a mold with a known interior size but you may use different materials to cast into it, and for each material, you'll have to calculate different A/B mix ratios, and some materials may expand.
