How do you embed a stone in boro?!

This can only be done with a stone that has the same COE as boro.

Or one can push a hole or dent in the glass and then epoxy the stone in the glass.

 

Why is soft glass unrepairable ?

Soft glass can not be cooled and reheated like borosilicate glass.   Therefore, if it is reheated it can crack or explode.  This is based on the COE of the glass and it expands way more than boro

Why should people “invest” in heady glass? What are the benefits compared to non heady glass?

People invest in heady glass we find because they love and appreciate the art of glass.  Glass is one of the toughest art mediums and can take decades to get good.  Heady glass is made by highly skilled artists and are rarely ever replicated again.

If you find a blower you like, do research, like any investment you could lose.  The artists have to be good, if not great, or at least up and coming.  Will they inspire?  Will they find their own path?  If yes, they could be an artist to invest in.

When you invest in a piece of glass it is more for the function.  Then when you invest in heady, it is more for the art.

What is the most unhealthy way to smoke flower by combusting? Pipes, Joints, etc?

We would think any way you smoke is much more unhealthy than vaping the flower.  But if you must consume we would think blunts are the worst with all the wrapper and additives.  Then we think the joints are next worse as there you have the paper, but less than blunts.  Then a pipe, then a water pipe.

 

As we are not doctors we do not know, this is just an observation based on reality.
