Heat your pan over medium heat, then add the bacon. Cook the bacon until it is crispy. Remove the bacon with a slotted spoon into a bowl and set aside.
Add your onion, celery, and oil or butter. Continue to cook over medium heat for about 3-5 minutes.
Sprinkle the flour on top and continue to cook, stirring consistently, for about 3 minutes.
Next add in your stock, clam juice, bay leaves, thyme, black pepper, vulcan's salt, 1 teaspoon kosher salt, and potatoes.
Cook over medium heat, stirring occasionally to make sure it isn't sticking to the bottom.
Once the potatoes are tender, add in the clams and half and half. Check for salt, add more as needed.
That is it! Serve with your favorite roll, bread, or cracker. Or, if you prefer, serve it just like it is!
