Question 1

What is लाल देवदारु काष्ठ (Redwood Timber)?

Accepted Answer

काष्ठ - Kāshtha (Redwood Timber), specifically शोणकाष्ठ (Śoṇakāṣṭha) or रक्तकाष्ठ (Raktakāṣṭha) referring to its reddish hue, possesses a density of 350-450 kg/m³ and a modulus of elasticity between 10-13 GPa. Its thermal conductivity is approximately 0.14 W/mK. While not traditionally sourced from the Indian subcontinent, hypothetical applications in Indic heritage architecture would necessitate careful consideration of its properties.

Assuming availability, Kāshtha could be utilized for structural beams (धरन – Dharana), exterior cladding, and decorative trim, mirroring uses in its native California. Durability, though inherent, would require enhancement via traditional oil-based preservatives (तैल रक्षक – Taila Rakshaka) to combat moisture and decay, crucial in varied Indian climates. Conservation efforts for hypothetical heritage structures would involve assessing existing damage, employing compatible repair materials, and implementing preventative measures against biological degradation. The Getty AAT lists "wooden collars" [1], a potential structural element where Kāshtha could theoretically be applied.
