I have a new MR glass :
sorry you can't see the bubbles.
I was In the Hunt for a new pan, ended up w a Demeyere saucier on sale
and then
http://www.zwillingonline.com/zwilling-sorrento-double-wall-glassware.html
they had a sale on all these vacuum glasses. there are many sizes. this is 10 oz
about the right size for an initial MR.
it a fine glass and does not need a coaster or the rubber-band cloth system Id been useing
it large at the hand hold level , so might not work for a smaller hand
very light and when soapy very slippery .
keeps the MR at just the right temp until the next refill.
