Is it possible to boil a yeast starter on an electric range, I know gas is better but I can't do anything about it

Just be sure to heat the water before adding the extract.

I boil my starters in an erlenmeyer on my glasstop. If using coil-type elements, you might want to use a wire spacer if using high heat.

The glass top acts as a hotplate if you have a ceramic glass stove. Otherwise you really should have a wire spacer even for a tempered glass. I may be an inexperienced home brewer, but I've worked with enough lab glassware to comment on this one...

My big question is how you cool the wort in the flask. You certainly can't go from boiling to cold water bath or CRACK!

Provided borosilicate glass is not subjected to rapid change in temperature, creating undue thermal shock, it can be operated safely at temperatures up to 450F (232C). The normal limiting factor is actually the gasket material. The degree of thermal shock (usually defined as sudden chilling) which it can withstand depends on many factors, for example: stresses due to operating conditions; stresses imposed in supporting the equipment; the wall thickness of the glass, etc. It is therefore undesirable to give an overall figure but, as a general guide, sudden temperature changes of up to about 216F (120C) can be accommodated

I am leaning more towards a pot at this point as this is my first starter and I would like to avoid broken/scarred glass.

My plan was to use a coil element stove and dunk the flask in a sink full of ice

olllllo you seem to know about this stuff, do you use a similar method/equipment?

Borosilicate will handle quite a change. In the lab, I go from boiling to very cold water and never lost one vessel yet. But I'm a little more cautious with the 5l erlenmeyer I paid for

I use my 1L Bomex borosilicate flask on my electric (coil element) stove all the time. Just make sure to put a spacer in there. I picked up a 2-pack of wire trivets/heat spreaders/whatever for $2, meant for coffee pots, at a local place. Previously, I thought I'd be smart and make my own out of some heavy-gauge bare copper wire, but that was a huge mess - it oxidized and got coated in this black ash that flakes off all over the place and makes a nice mess.

Cooling it is not that hard, I generally take it off the burner and let it sit on the stovetop for a few minutes, and then dunk it in some hot tap water for a minute or so, and then put it in cold water and start adding ice as needed. I wouldn't dunk it straight into ice water from the burner.
