Mushroom ketchup is a style of ketchup (also spelled "catsup") that is prepared with mushrooms as its primary ingredient.

Callaloo (sometimes calaloo or kallaloo) is a popular Caribbean dish originating in West Africa served in different variants across the Caribbean.
 The main ingredient is a leaf vegetable, traditionally either amaranth (known by many local names, including "callaloo" or "bhaaji"), taro or "xanthosoma".
 Both are known by many names, including "callaloo, coco, tannia, bhaaji", or "dasheen" bush.
 Because the leaf vegetable used in some regions may be locally called "callaloo" or "callaloo bush", some confusion can arise among the vegetables and with the dish itself.
 Outside of the Caribbean, water spinach is occasionally used.
 Trinidadians, Grenadians and Dominicans primarily use taro/dasheen bush for callaloo, although Dominicans also use water spinach.
 Jamaicans, Belizeans and Guyanese on the other hand use the name callaloo to refer to amaranth, and use it in a plethora of dishes and also a drink ('callaloo juice').
 The 'callaloo' made in Jamaica is different from the 'callaloo' made in Trinidad and Tobago and Grenada in terms of main ingredient (the leaf used) and other ingredients included (for example, Jamaicans tend to use only callaloo leaf, salt, onions, and scallions, and simply steam the vegetable, while Trinidadians use okra and coconut milk to make a different dish with a different taste and consistency).

Ngapi (Burmese: ငပိ or ငါးပိ ] , literally "pressed fish"), formerly also spelled ngapee, nga-pee, and gnapee, is a generic term for pungent pastes made of either fish or shrimp in Burmese cuisine.

The Unit Deployment Program (UDP) is a system for assigning deployments of the United States Marine Corps.
 To reduce the number of unaccompanied tours and improve unit continuity, the Commandant of the Marine Corps, (CMC) established it to provide for the deployment of units to the Western Pacific (WESTPAC) for periods of approximately six months.
 The initial program was a six-phased evolution that sequenced infantry battalions and aircraft squadrons/detachments into WESTPAC deployments, thus eliminating the 12-month permanent change of station assignments for personnel assigned to these units.
 The program commenced in October 1977 and has proceeded through the six phases.
 In August 1985, tank companies began phasing into the program but following Southwest Asia, were discontinued.
 In Fiscal Year 1987 (FY87) and FY88, Amphibious Assault Vehicle (AAV) companies and direct support artillery batteries were phased in and later, Light Armored Reconnaissance (LAR) companies were also included in the program.
 The Marine Corps’ objective is to adhere as closely as possible to a six-month period of deployment away from a unit’s Continental United States (CONUS) home base.
 In the case of Hawaii-based infantry battalions, which employ a three-battalion rotation base, a seven-month period of deployment is executed to support the Unit Cohesion Program and efficient staffing of first term Marines.
 It must be understood, however, that shipping or airlift schedule variations, and exercise or contingency operations will occasionally necessitate longer or shorter deployments for participating units.
 It is imperative that all personnel involved in these deployments be kept fully informed of planned deployment duration and subsequent deployment schedule changes.
Drywall (also known as plasterboard, wallboard, gypsum panel, sheet rock, or gypsum board) is a panel made of calcium sulfate dihydrate (gypsum) with or without additives and normally pressed between a facer and a backer (typically thick sheets of paper).
 It is used to make interior walls and ceilings.
 The plaster is mixed with fiber (typically paper and/or fibreglass), plasticizer, foaming agent, and various additives that can decrease mildew, increase fire resistance, and lower water absorption.
A Dymaxion deployment unit (DDU) is a structure designed in 1940 by Buckminster Fuller consisting of a 20-foot circular hut constructed of corrugated steel looking much like a yurt or the top of a metal silo.

 The dome-like ceiling has a hole in the top and a cap for ventilation.

Question: What is the main ingredient of the finishing material inside the Dymaxion deployment units?
Answer: calcium sulfate dihydrate
