Dry Heat Sterilisation

[Heavy Iron]

Is there any reason this couldn't get the job done?

It reaches 450°F. It's basically a counter top oven. But I wouldn't ever cook anything in it.

That might work
and so will a conventional oven

just make sure you wrap the items in several layers of Aluminum foil
otherwise they'll become unsterile again right when you pull them out of the oven.
Hot-dry sterilization. Metal instruments, glassware, aluminum foil, etc., can be
sterilized by exposure to hot dry air (130°-170°C) for 2-4 hr in a hot-air oven. All
items should be sealed before sterilization but not in paper, as it decomposes at
170°C.

And my favorite:
dipping in alcohol and flaming it
Flame sterilization. Instruments can be dipped in ethyl alcohol and flamed to burn off all bacteria and fungi. Safety is a major concern when using ethyl alcohol. Alcohol is flammable and if spilled near a flame will cause an instant flash fire. This problem is compounded in laminar flow hoods due to the strong air currents blown towards the worker. Fires commonly start when a flamed instrument is thrown back into the alcohol beaker. In case of fire do not panic. Limiting the supply of oxygen can easily put out fires.

Yeah I just don't want to put my glass where I put food too. Lol.

A mini oven dedicated to glassware seems ideal. And they are pretty cheap.

It's your call, but they work the same.

To prevent contamination you need to wrap glassware in Aluminum foil, no matter if food or dedicated oven
for extra safety/cleanliness:
after baking them you can clean the Aluminum foil wiping it with some alcohol and allow it to dry before unwrapping the foil open
(allow it to cool off before wiping it with alcohol).
