Ceramics/Pottery also covers bricks (really only shoddy and average), which is the closest thing I could find. Maybe half the cost of Pottery for Stone? That would place fancy marble at 350 pounds per ton.

Oops, wrong thread for that.
That is a nice collection of items for a covenant on an island.
Growing trees in a day and then cutting them down is a fantastic idea - I must remember that one...
In our covenant we had a device to make parchment from goat skin - it was far more efficient than making it by hand. Not just because of the time but also because there is a lot of wastage when making parchment the normal way.
We also had a magus who wanted to use some perdo/rego terram magic to make a river easier to transport goods.
One of our magi is a goldsmith, he made a simple invested device that could shape gold into a ring. Size, shape and decoration all determined by finesse. These rings were then sold through the goldsmith shop. The locals thought that there were several journeymen churning them out, but really the magus spent a few hours each month to make a batch of rings.
Yea, being stuck on a very big island (some 2200 acres) in the Med means we have plenty of space but have to take a ship (or a portal, much later in the campaign) to somewhere to get things we didn't have.
Since for the longest time all of our ships were small (the Shipyard is a little over 50 years old, but the game has been going on for 101 years) and we didn't have portals until about 30 years ago so we imported skilled people when we could and made a whole ton of lesser enchanted items.
Our magus perform 1 season a year in support of the covenant. While that could be anything from representing us at Tribunal, writing books for our library, using magic to build things, or securing a new Vis source, the most common choice has been to enchant magical items.
When you have 8 players (though one is primarily the SG), you end up with a lot of Magus. We started with 9 (two were elders who founded our Covenant, controlled by the guy who was the primary SG), but have lost the two elders (one to Twilight, one to dead by horrid aging roll). We are currently at 8 since the Mercere Magus who is part of the group keeping an eye on us is the primary SGs current character.
Long way of saying we have over 400 enchanted items that belong to the Covenant, out of some 850 seasons of service. (math was high)
... You must have had some very fine Vis sources!
We started with an average of 32 (19+1D3+2D10) a year, with most 'discovered' (paid for with BP) during the first year. Covenant gets 1/3 (covers AotH, enchantments & rituals for Covenant), 2/3 split by the Magi.
Developed it up to... beep I'm not writing all that out in detail this early... we added nine random sources though adventures/industry and built them up. Six 1D3 (half 2 pawns per) sources, a fish pool current holding 27 pawns that increases by a variable based on how many it holds (currently 1D6+2), 1D3 @ regio level truffles (1 must be sacrificed every year to maintain), and a small possibility of Vis for books (we tend to trade to expand library).
The starting amount felt fine (even high) at the beginning when we were scratching to build and survive, but then we hit a point where we got Vis hungry and spent a lot of game time/adventure/service seasons looking for and cultivating new sources.
Also most of the enchanted items are 2 or 3 pawns of Vis per.
Lots of them are duplicates, there are only 86 different Covenant enchanted item types. Things like the "... of Viscid Clay" tools, "Unseen Porter" carry handles, and Eternal Lanterns are all very cheap to make. Copies of just those three account for over a quarter of our items.
The lanterns for example are CrIg base 3 (bright as a torch), Sun duration (+2M), 2/day and Environmental Trigger so a combined 9. 1 pawn of Vis each and so easy to make that an apprentice might be able to knock out two in a season with a lab text, since they get a +7 form bonus. We use a shuttered lantern to build them, so you can effectively turn them off. We have 81 of them, scattered all over the Covenant, with a few for travel and trading co.
EDIT: Fixed the Vis cost, I for some reason stuck the number from using Ritual Magic there.
Just want to be sure I understand, why would a Lesser Enchantment that is under a 10 in level cost 2 vis? In the description of Lesser Enchantment on p96 of the Core book it says that investing an item cost 1 vis per 10 levels or fraction thereof. That said, if there is a Lab Text already created, can someone with a Creo Ignem Lab Total of 27 make 3 in a single season?
My bad on the Vis cost, I for some reason stuck the ritual cost in when I typed up the post.
As for creating multiple copies of an enchanted item in a single season, see AM5 page 102 "Multiple Laboratory Activities". As long as all the actions are the same type of activity and require the same Arts, you can do up to as many as your lab total allows. So yes if you had a lab total of 27 with a lab text, you could create 3 in a single season.
Note that you still require a high enough Magic Theory to spend the total Vis used, since that is the total you can use in a single season. For three of these, it would only require a MT of 2.
My Magus created 10 of them in a single season the last time he did this is play and the number would be even higher now (12 I believe, though I would have to check the total).
