We enjoy our glass toys, and the Mrs. enjoys hers warmed - not "hot" but warm, for sure.

We started with just hot water in the sink, and we've moved to a tiny slow-cooker/crock-pot, but cheap pots only have 1-2 temperature settings and "ON" is too hot in the one we have - which means we have to wait patiently for them to cool a touch.

Has anyone used anything similar for heating their toys? We're considering, perhaps, bottle warmers (cheap, plentiful, can grab one at any T* or W* store), adjustable electric blankets (more than HI-MED-LOW), adjustable pet blankets...heck, maybe even a small tub of my own with a fishtank heater or a new sous vide machine just for perfect temperature control glass toys.
