I have to attach this threshold on top of some porcelain tile (edge of shower) and have it at a slight angle to shed water.
What's the correct way to attach this to the tile? Should I use mortar and lay it in like a piece of tile ? Or just throw a bunch of silicone caulk down and press it into that?

You are going to need to scour the exiting tile at worst, remove them first at best. There are roll on products that you can buy to coat the tile and the back of the jam/threshold to promote a bond, then use multipurpose cement to install it. If there is considerable overhang into the shower, consider cutting a drip edge onto the bottom of the threshold inside the shower.
Polyurethane will give best results, if the tile is in decent shape I'd leave it and just clean the hell out of it.
The trick is that you want to bed the part in enough sealant that it squeezes out of both the front and back and sides edges leaving no bubbles or gaps for water to be trapped anywhere.
For the slope I would cut a strip of material that won't rot like plastic to act as a shim along the high side but back from the edge, stick it down first so it can't move (after triple checking dry fit of all parts), apply the sealant/glue to the cobtact areas and bed it in.
Then I'd put some weight on top like gallon jugs of water or bricks or something to keep it flat until it cures.
When you dry fit it's a good idea to tape off the surrounding areas to make cleaning off the squeeze-out easier and cleaner. If you need to tool the seams with a finger wear, nitrile gloves and wet the finger with mineral spirits.
The tile is brand new , the shower pan is below grade(like step down/into), and they just tiled up to the edge. The glass guy said he won't install glass without a threshold because it would splash into the room and I couldn't have a rug with out it hitting the door.
I guess the polyurethane is for the adhesive part , and then I just have to put regular white silicone around the edges ?
I find it hard to understand your issue
Don't the tiles go past where the glass will be ?
Why does he need a porcelain threshold to mount the glass on
The glass needs to be above the ground, there is no shower curb as the pan is below grade, so he said I need to install a threshold there.
But the step and everything has to be sloped and water proofed right?
From a purely technical standpoint he's full of shit, shower enclosures and other glazing sit directly on tile and other hard flooring all the time.
I mean, there may be some kind of setting channel or clips and a gasket or other manufactured seal involved, but curbless *and* frameless shower enclosures are a thing that any competent installer should be aware of.
Do a search for curbless shower enclosures, there's dozens of examples.
Its also weird that if he's insisting on some threshold as part of his installation, he's expecting someone else to install it.
He says that he has had too many complaints from people that there is water splashed on the floor and they can't use rugs outside the door, because it would push them away. And he is the only person that installs shower glass in my shit down.
shit town, sorry I am still drunk
>I guess the polyurethane is for the adhesive part , and then I just have to put regular white silicone around the edges ?
if you do it right theres no need for silicone or other sealant, but if you wanted to add it you could.
That's the point of bedding parts and fixtures in, they sit in/on a solid "bed" of sealant with no gaps to worry about.
IOW the gluing it down part *is* the caulking part.
