Any ideas on how to joinn two pieces of insuating glass @ an outside 90 degree corner, in a minimalist fasion? The installation will be in exterior walls in a moderately cold climate. If the installation were on the interior or it was a situation where condensation was not an issue, sthe solution would be to use clear silicone sealant and non insulating glass. With insulationg glass I’m concerned about the appearance of the edge seals and that the edge seals might be mor prone to failure.

You might consider using Lexel. The tube claims it's tougher than silicone and 19 times clearer than silicone. It's made by a company called Sashco. I've used it and really like it.
Thanks for responding. I will investigate the suggested sealant. Thanks again
We've used a square aluminum tube the same size as the glass thickness (3/4 x 3/4 for 3/4" glass, for example). You place the tube in the corner and butt the glass to it. It's no more view obstructing than the edge of the insulated glass, and if gives you a way to cover the exposed edges. It gets set in place with Dow structural silicone sealant.
