opal sticking to kilnwash - can I use plaster/silica plate?

Hi
Have to make lots (and I really mean lots) of little opal balled up bits. The kiln wash sticks to them. Have successfully cleaned them up in my rotary tumbler. No media, just all the bits, water just to cover, couple tablespoons of #80 silicon carbide, about 4 hours.
It works, but cleaning up afterwards is a nightmare. The wet silicon carbide sticks to everything, is too expensive to throw away...though very tempting . It is winter, cold and windy. Have to do all the washing on the veranda, while I mutter Tom Jones song "Baby its cold outside" through clenched teeth.
So thought to pour plaster/silica mix on a few plastic plates, this will give me a flat surface that I don't need to kilnwash.
My question is: will the opal bits not stick to the plaster/silica? I have only used simple open faced molds with gaffer glass, have no experience at all with the BE opals.
Hoping someone will tell me it works well, no sticking. Then I can make lots of flat surfaces and have the mess (mixing the plaster/silica and all the cleaning up afterwards) only once .
Many thanks as always, seachange
