The primary purpose is to inspect products and make timely corrections when issues are discovered. ## 1. How to Create Technical Drawings When you receive a teapot, first remove the lid. Use calipers to accurately measure: (1) outer belly diameter, (2) mouth diameter, (3) base diameter, and (4) height excluding the lid. Record these measurements carefully. If replication is needed, increase dimensions by 10%, then proceed to draw the diagram. First sketch the body outline, then draw the lid. According to requirements, mark cross-sectional views on half of the front elevation. This constitutes a complete technical drawing. ## 2. Calculating Dimensions With the technical drawing complete, you can now calculate dimensions. The body mold cross-section is called the front elevation. The inner belly diameter forms the circular edge—this dimension is the circumference. The rim—this is the large opening dimension. The base—slightly smaller than the false bottom. ### Calculating Clay Strip Dimensions We employ a traditional method: at the widest point of the outer belly diameter, connect two points with a straight line, using the center point as the compass foot. Take a relatively soft wire and measure along the outer contour line (excluding the large opening area) to determine the outer contour's length. However, this length is not the height of the clay strip. If you use this height to form the body, it will be too tall. There is a fundamental principle here: the outer contour line length must be shortened. The larger the belly diameter and the smaller the base rim, the more the length should be reduced. Following this logic, first form one body to observe the shape effect, then make corrections accordingly. ## Full Handmade Teapot Formation Process This particular teapot is made from pink clay, so pink clay strips must be used. First, beat the clay strips to prepare the red clay, then beat the base rim to prepare the base piece. Both the prepared clay strips and pieces need to be evenly smoothed with a paddle. Immediately after, soak the spout clay, then...
