Both the Light switch and Door knob were used in Box Cottage during the late 19thC and early 20thC by the Box and Rietman families. William and Elizabeth Box purchased the two ten acre Lots of land with the Cottage in 1868 where they raised their family of 12 children and developed a flower garden producing seedlings. August and Frieda Rietman rented the Cottage 1917 with 1 acre of land and purchased it in 1935 where they raised 2 children while August established Rietman's Landscaping Pty Ltd making pressed concrete garden furniture. Porcelain is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C The toughness, strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. Porcelain and other ceramic materials have many applications in engineering, especially ceramic engineering. Porcelain is an excellent insulator for use at high voltage, especially in outdoor applications, see Insulator (electricity)#Material. Examples include: terminals for high voltage cables, bushings of power transformers, insulation of high frequency antennas and many other components.

This insulator disk for the high voltage carrying electrical cables was manufactured in 1964 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to connect high voltage cables to their "towers" going from various Hydro Generators to and from power "stations". During this time period, high quality "cable" insulators were manufactured in Japan. In an earlier time they would have been sourced from Europe or England. After the 1950's the sourcing of electrical hardware was being influenced by the lower costs obtainable from Japan. Later on other Asian sources also became available.The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to distribute the electricity produced in the Victorian Alps to the major users required power transmission lines to "carry" high above the sometimes inaccessible land mass electricity generated at the power stations to the various sub stations along the valleys and ranges to flatter populated regions. The significance of this insulation "high voltage" disk to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. These power lines are a stark visual "show" of the impact that the "Scheme" has on the mostly rural landscape of the Kiewa Valley and what a boost of "modern" equipment into the area has taken place. The "Hydro Scheme" had facilitated the transition of a semi rural area to an advanced rural region within a shorter time frame, than would have taken under "normal" evolutionary time. The speed of information of all "new technology" had a relatively slow assimilation rate before the SEC Kiewa Hydro Scheme came to those living in the then quieter rural communities. This high voltage (330 KV) insulation disk is made from non conductive porcelain stoneware. It is highly polished brown in colour and has a clip fastening for the high voltage cable to be attached to. This disk was hit by lightning and the burn marks are quite noticeable. The top metal connector has a "mushroom" extension jutting below the semi cone like insulation disk. Also four circular ridges or grooves (old 78 rpm disc recording style).Cable bell on top of insulation disk "4K " next to it the international symbol for electricity (triangle containing one horizontal line under one V line and one vertical flame like line.)

This insulator was used on phone wires. Insulators were originally designed to keep the wires linking telegraphs and telephones insulated from the wooden poles that held them aloft. Prior to 1925, Australia relied solely on insulators imported from other countries. Glass insulators were first manufactured in Australia in c. 1926 by Australian Glass Manufacturers. Their factory was, and still is, located on South Dowling Road in Sydney. Australian Glass Manufacturers (A.G.M.) had developed a toughened type of glass very similar to Pyrex glass. Since the Pyrex name could not be used due to trademark infringements, they called their glass AGEE for Australian Glass. Many fruit jars, insulators, pie dishes and other glass items were manufactured with this AGEE trademark during the 1926 to 1940 period.Glass insulators are rapidly becoming a thing of the past in Australia with open-wire communication lines rarely existing near metropolitan areas. The remaining open wire lines are being abandoned and dismantled everywhere with very few insulators being saved as interest in them in Australia is quite limited.

Modern communications technology arrived on Gabo Island with the construction of the telegraph line from Eden to Gabo Island in 1870. This type of insulator was usually used with radio antennae wires, telegraph and radio antennae equipment. The items of telegraphic equipment comprise a number of ceramic and glass insulators of varying age and type. Five, knuckle-shaped white glazed ceramic examples are associated with radio antennae wires. In addition to insulators, there is a telephone insulator bracket made of metal with wooden pins. It was once attached to the top of a steel pole and some of these remain in situ along the former telegraph line. Telegraphic communication commenced at the Gabo Lightstation in 1870, just eight years after the lightstation opened. The line from Sydney reached Eden, NSW by 1868 and was then extended to Gabo with the costs shared equally by NSW and Victoria. It was initially carried on posts across the sea to the island but was changed to a line along the seabed after the posts were washed away. The first telegraph office was a timber building on east side of the assistants’ quarters. In 1887 a new concrete telegraph office was built which included quarters for the operator, with Victoria and NSW sharing the construction costs. The 1992 CMP identified remnants of the line from its various phases of operation, and these can still be seen in 2016. Other ceramic insulators in the collection are associated with lines supported on utility poles for the transmission of high voltage electricity. .The various insulators have second level significance for their historic value and provenanceFive white glazed ceramic insulators.
