Study unique artistic lopburi province for design brass tea set of bantahkrayang community

The objectives of this study were as follows: 1) to study the production process of handcrafted Brass Tea Set; and 2) to design and develop the handcrafted of Brass Tea Set. The process of design was started by mutual analytical processes and conceptual framework for product design, Quality Function Deployment, Theory of Inventive Problem Solving, Principles of Craft Design, and Principle of Reverse Engineering. The experts in field of both Industrial Product Design and Brass Handicraft Product, have evaluated the Brass Tea Set design and created prototype of Brass tea set by the sample of consumers who have ever bought the Brass Tea Set of Bantahkrayang Community on this research. The statistics methods used were percentage, mean ( X ¯ = ) and standard deviation (S.D.) 3. To assess consumer satisfaction toward of handcrafted Brass tea set was at the high level.


Introduction
Bantahkrayang Community, Tahlaechupsorn District, Lopburi Province, one of villages inherits the intellect of creating the local handcraft. Brass is a metal handcraft and always a popular local handcraft of Bantahkrayang community that is inheritance from the past. The manufacture of Brass is evolved from skills of what the body of knowledge is collected via inheritance, improvement and development. Then it transforms into the Brass at present.

Moreover, it cast into the artistic and animal shapes [1].
The Occupational Group of Brass Caster, Bantahkrayang is facing with the issue of product shape that the design development isn't various, the number of consumers are decreased, the purchases order of exportation are also decreased due to inbound competitors who manufacture the Brass instead. Moreover, the national competition of producing the Brass is increased for provinces at present. The cost of Brass and fuel oil is more expensive [2].
The Brass Tea Set is one of a popular product among the consumers who love making of tea. The shape of Brass Tea Set of Bantahkrayang Community can buy anywhere and it's not unique.

It's to add the value of product and the distribution channel. It's also the everlasting conservation of Brass casting which is the intellectual of Thai people.

Objective
 To study on identity and the production process of handcrafted Brass Tea Set  To design the handcrafted Brass Tea Set  To assess consumer satisfaction toward of handcrafted Brass tea set

Research methods
The methodologies of this study were as follows.

Study the production process and the style of Handcrafted Brass Tea Set
The researcher studied the production methods of handcrafted Brass Tea Set by document, book, interview and the related study. Then all the data were analyzed and approached to the development of Handcrafted Brass Tea Set.

Design the Handcrafted Brass Tea Set
Design the Handcrafted Brass Tea Set that based on a theory of Wiroon Tungcharoen [3]. This theory was applied to the design relating to the quality of product, and it is a conceptual product development, The instruments used were primary data collection, interviews and questionnaires. the designing process then started by using collected data, through analytical processes with conceptual framework for product design; The Quality Fucnction Deployment, the theory of inventive Problem Solving, Principles of Craft Design, and the Resverse Engineering Principle. The experts from both the fields of Industrial Product Design and Brass handicraft product, whom concern Brass Tea Set format, were included to evaluate the design and creats prototype of brass tea set, the researcher have drafted 30 models of sketch Design and by using "Reverse engineering" to analyze, the best 3 forms were selected and assessed by experts and creats prototype of Brass Tea Set.  . Shows drafted 30 models of sketch Design and by using "Reverse engineering" to analyze, the best 3 forms (Fig.27 Fig.13 Fig.10) were selected and assessed by experts and creats prototype of Brass Tea Set. Researchers have drafted 30 models of sketch Design and by using "Reverse engineering" to analyze, the best 3 forms were selected and assessed by experts. the handcrafted expert gave an opinion to the design of Brass Tea Set as follows; Design 1 was the most favorable of 3 designs by means (x 0, S D 0 hen each aspect was considered, it found that Total mean of esthetic x 33, S D 0 3 Total mean of the matching with usability x , S D 0 3 Total mean of the optimum of production material x 3 , S D 0 and Total mean of the matching with production x 00, S D 0 3

The result from the study of the identity and process of brass tea set
The result from the study of the identity and process of brass tea set craft is found that, the identity of Lop Buri province is its ancient land since prehistoric period, which has many archaeological evidences, such as ancient community, ancient remains, antiques, and the Lop Buri's animal which is monkey living with the resident for a long time. Nowadays, brass tea set has varied process, which are 1. Forging shape forming, 2. Turning shape forming. These processes are complex and need manufacturing only the community cannot produce by itself Thus this research is applied "Lost ax" to produce Brass Tea Set so that the community is supported to produce Brass Tea Set by itself

The design and development of handicraft products, brass tea sets
The design and development of handicraft products, brass tea sets Ban Tha Kra Yang community, Lop Buri Province, found that the identity of Lopburi province was related to the Slogan of the province. It was inspired to design pattern include monkey, wang Narai, phra prang sam yod and pikul flower of Lop Buri Province, By analysis the handcrafted expert gave an opinion to the design of Brass Tea Set as follows; Design 2 was the most favorable of 3 designs by means (x = 4.61, S.D.=0.42). When each aspect was considered, it found that (1) Total mean of Aesthetic, Results the design study Brass tea set of Bantahkrayang it was inspired by shape relating to Historical remains of Lopburi Province, and designed in the framework of the core of the industrial design Udomsak Saributr [4] consider all 4 sides Aesthetic, Function, Manufacturing, The matching with production Researchers have drafted 30 models of sketch Design and Analytical principles "Product Design Theory" To select the appropriate model of the product.

Consumer satisfaction assessment results for Brass Tea Set Handicraft
Consumer Satisfaction Assessment Results for Brass Tea Set Handicraft The results of the study on identity and production process, as well as the design and development of brass tea set in Bantahkrayang Community to consumer satisfaction was to assess consumer satisfaction toward Brass tea set, Total mean of esthetic x 33, S D 0 3

Discuss and summarize
According to the study on Handcrafted Brass Tea Set of Bantahkrayang Community divided into 3 parts.
The study of Handcrafted Brass Tea Set production process and design, it was found that the casting of wax models could be applied with other metal casting, for example, silver, copper and accessory molding work, which is in accordance with the research from Phensri Tongnoppakhun for developing the process of molding in accessory industry, which is careful process in order to reduce the damages and mistakes of works to the least [5].
To design the handcrafted of Brass Tea Set. The instruments used were primary data collection, interviews and questionnaires. The designing process then started by using collected data, through analytical processes with conceptual framework for product design; The Quality Function Deployment, the theory of inventive Problem Solving, Principles of Craft Design, and the Reverse Engineering Principle. The experts from both the fields of Industrial Product Design and Brass handicraft product, whom concern Brass Tea Set format, were included to evaluate the design and creats prototype of brass tea set.
To assess consumer satisfaction toward of handcrafted Brass tea set was at the high level.

Consumer satisfaction assessment results for Brass Tea Set. Consumer Satisfaction Assessment
Results for Brass Tea Set Handicraft was shown that there were 2 consumer groups, one have bought to use daily and another have bought for home decoration. Thus, the product design should be varied for usability so that the consumer groups can be more varied and increasingly. These suggestions could be applied to improve the data on the design of Brass home decoration product development.
