Aerosil R 202 Hydrophobic Silica - Fumed silica is an ideal filler and bulking agent when used with casting resins. The casting resins are used to restore, strengthen, and replicate archaeological artifacts.

Structural Channel Steel -  This steel channel will form the lifting hardback under the fragile wooden keel and will stay with the Belle for the rest of her days while on public display in the museum.

Quick-Setting Epoxy - The five-minute epoxy donated by Devcon Plexus is an extremely versatile glue that is used in a multitude of ways in the lab. The epoxy has a very good bonding strength, and sets up rapidly. It is used mostly to glue the broken pieces of a cast replica of an artifact back together after casting so that the viewer has a better idea of the original shape and size of the artifact. The epoxy is used to glue the various pieces of a natural concretion mold together so that a replica of the original artifact can be cast in the mold.

Hysol Epoxy - Hysol Epoxy donated by Dexter Corporation is used in the casting replication of metal artifacts which have completely deteriorated. Epoxy is poured into natural molds left in encrustations. Once the epoxy sets, it is removed using from its surrounding concretion pneumatic chisels to reveal an epoxy cast exactly replicating the original object prior to its decomposition.

Control Panel Lights - These lights are used on the winch control panel to inform the operator of the status of the winch system - auto/manual mode, up/down, standby, etc.

2000-Gallon Water Tank - The 2000-gallon water tank donated by Diamond Fiberglass Fabricators is used to collect rain water. Objects undergoing the rinse process to remove soluble salts are taken through a series of rinse stages. In the first stage, the objects are rinsed with tap water. In the second stage, rain water is used to rinse objects; deionized water is used in a third stage to complete the sequence. This process brings objects through rinses with progressively less soluble salts until they have been completely removed from the artifact.

Vellum & Tracing Film - All conservation laboratories need a good supply of this material to accurately record the artifacts, before, during, and after the conservation process.

Electronic Dynamometer - The 5000-lb. capacity electronic dynamometer (scale) donated by Dillon will enable the lab to accurately weigh heavy artifacts, such as the two cast bronze 4-pound cannon from the Belle and the eight cast-iron cannon from the Fort Saint Louis site.

Timers - The two darkroom timers donated by Dimco-Gray are indispensable in the photographic development processes used in the lab. Accurate timing is a necessity when developing black-and-white film and X rays, both of which are integral to the conservator's work of recording artifacts.

Bulk Chemicals - The conservation of both ferrous and non-ferrous artifacts requires vast quantities of chemicals during the electrolytic reduction and cleaning processes. Sodium hydroxide and sodium carbonate are two of the bulk chemicals donated by Dow Chemical Corporation.

Solvents- These are necessary in many aspects of conservation, from the incremental stages of dehydration of organic materials to producing solutions for the consolidation of artifacts.

Chemicals - Dow Corning has been a long-time contributor and supporter of CRL, with on-going patent and applications research with Texas A&M University and the donation of silicone oils, polymers, lab materials, and technical expertise in research designs. Joint research between TAMU and Dow Corning has significantly contributed to our research, developing new technologies for archaeological conservation and industrial applications for organic preservation.  The silicone molding compound is used to make mother molds when composite artifacts have to be replicated.

Fresh-Water Tanks - These two tanks are used to collect and store rain water. The rain water is used in one of the stages of rinses undergone by artifacts to flush out soluble salts prior to conservation.

Engineering Design and Fabrication - Dynacon donated the design and fabrication of the steel platform and winching system that is used to raise and lower the Belle in the new concrete conservation tank. The platform has the capacity to lift 30 tons with minimal deflection so as not to stress the wooden hull of the ship.  This equipment has been installed in the new ship conservation tank, where the Belle is currently being reconstructed.
