Lin's Ceramics- yellow clay kettle & burner

[stephanieayres]

Hi all,
I'm new here, but was wondering if anyone has one of Lin's Yellow clay kettles and unadjustable alcohol burners for sale.

Can anyone also tell me the benefits of an adjustable vs a non adjustable stove when you are just learning to boil water properly?

Any help appreciated!

All the best,
Stephanie
