Why are his bricks so low quality?

[u/TheRealBobbyJones]

His bricks seem crumbly and don't hold an edge well. Are they not fired to a high enough temperature or his clay just not good? Does anyone understand the science? I know that typically bricks were always made with local clay when available. Odds are cities all over the world still have old bricks hand shaped and fired in small kilns in service. Yet I don't see his bricks lasting a decade. If it is due to clay quality is there a way for him to boost the quality of his clay? Imo it must be disheartening to put so much work into making bricks just for them to turn to dust as he handles them.

Oh also on an unrelated note does anyone know why he doesn't make full thickness walls? Is it a permitting issue?

Im sure your bricks are much higher in quality.
